■ Paper- Patients with idiopathic carpal tunnel syndrome (CTS) exhibit impaired mitochondrial function in the subsynovial connective tissue (SSCT) of the carpal tunnel. We hypothesized that Imeglimin, a compound known to enhance mitochondrial function, may improve mitochondrial activity in SSCT from these patients. This study aimed to evaluate the effects of Imeglimin on mitochondrial function in SSCT-derived cells obtained from patients with idiopathic CTS. SSCT samples were collected from 15 patients (mean age: 67.5 ± 9.7 years) who underwent carpal tunnel release surgery between April 2022 and March 2024. The cells were cultured under control conditions (Dulbecco's Modified Eagle Medium alone) or with 100 µM Imeglimin for 24 h. Mitochondrial function was assessed using multiple assays, including cell proliferation, superoxide dismutase (SOD) activity, apoptosis rate, mitochondrial volume, membrane potential, reactive oxygen species (ROS) production, gene expression related to mitochondrial biogenesis and antioxidant capacity, mitochondrial permeability transition pore opening, and ultrastructure by transmission electron microscopy. Statistical analyses were performed using the Mann-Whitney U test, one-way ANOVA, Kruskal-Wallis test, and Fisher's protected least significant difference test, with p < 0.05 considered significant. Compared with the control group, the Imeglimin-treated group showed significantly increased cell proliferation, SOD activity, mitochondrial membrane potential, mitochondrial volume, cristae density, and expression of genes related to mitochondrial biogenesis and antioxidant defense. Apoptosis and mitochondrial ROS production were significantly reduced (p < 0.05). These findings suggest that Imeglimin may enhance mitochondrial function in SSCT-derived cells from patients with idiopathic CTS, offering a potential therapeutic strategy for mitochondrial dysfunction in CTS.Oct. 2025, Journal of orthopaedic research : official publication of the Orthopaedic Research Society, English, International magazineScientific journal
- BACKGROUND: Glutaminase 1 (GLS1) degrades glutamate into glutamine and ammonia, and is required for the survival of senescent human cells. GLS1 inhibitors contribute to the improvement of various pathological conditions associated with aging. Rotator cuff tears (RCT) increase with age, and recently the Stump classification has been proposed to evaluate the fragility of the torn rotator cuff site, with Type 3 being the most fragile and a high risk of re-tear after rotator cuff repair surgery. We hypothesized that GLS1 expression is upregulated in the degenerated rotator cuff and that GLS1 inhibitors would improve rotator cuff degeneration. In this study, we evaluated the effects of GLS1 inhibitors on human rotator cuff-derived cells. METHODS: Twelve patients who underwent surgery for RCT were included in this study. Rotator cuff tissue was harvested during arthroscopic repair for tissue and cell evaluation. Tissue evaluation involved quantitative assessment of mRNA expression of GLS1 using real-time PCR (qPCR) and immunostaining. Rotator cuff-derived cells were isolated and cultured, divided into four groups: (1) Control group (without IL-1β and GLS1 inhibitor), (2) IL-1β(-)/GLS1 inhibitor(+), (3) IL-1β(+)/GLS1 inhibitor(-), (4) IL-1β(+)/GLS1 inhibitor(+). Cell viability was evaluated by WST assay and mRNA expression was evaluated by qPCR at 48 h after treatment. The expression of p16 and Scleraxis (SCX) was also evaluated by fluorescent immunostaining. RESULTS: Tissue evaluation showed significantly higher expression of GLS1 in Stump classification Type 3. Cell viability was significantly decreased by IL-1β loading and increased by the GLS1 inhibitor. The mRNA expression levels of GLS1, IL-6, p16 and p21 were decreased by the GLS1 inhibitor. The mRNA expression of the tendon markers, type 1 collagen, Mohawk and SCX were increased by the GLS1 inhibitor. Immunostaining revealed that the GLS1 inhibitor decreased p16 expression and increased SCX expression. CONCLUSIONS: This study showed that GLS1 was upregulated in the degenerated rotator cuff, and that the administration of a GLS1 inhibitor decreased inflammation and aging markers while increasing cell viability and tendon markers in rotator cuff-derived cells. These results indicate that GLS1 inhibitors exert anti-inflammatory effects in rotator cuff tears, prevent age-related degeneration of the rotator cuff, and promote tendon repair.Oct. 2025, BMC musculoskeletal disorders, 26(1) (1), 935 - 935, English, International magazineScientific journal
- Carpal tunnel syndrome (CTS) diagnosis is typically confirmed through electrophysiologic studies and ultrasound (US) imaging. Recent studies have suggested that median nerve gliding is reduced in patients with CTS. This study employed particle image velocimetry (PIV) to analyze median nerve dynamics. Ultrasound movies were captured during finger flexion and extension for 20 healthy volunteers (control group) and 20 CTS patients (CTS group). These movies were then analyzed using the PIV method. Within a 10 x 10 mm² region of interest (ROI) that included the median nerve and flexor tendon, the velocity magnitude and vector direction of movement were examined using PIV software. The maximum and mean velocity magnitudes were compared between the two groups using the Mann-Whitney U test. The maximum velocity in the ROI was significantly lower in the CTS group (9.3 ± 3.0 mm/s) than in the control group (11.5 ± 3.4 mm/s). The mean velocity was also significantly lower in the CTS group (1.7 ± 0.3 mm/s) than in the control group (2.5 ± 0.7 mm/s). Regarding motor properties, transverse motor velocity was significantly lower in CTS patients than in controls, while vertical movement showed no significant difference between the two groups. This study applied the PIV method to US images for dynamic analysis of the median nerve, revealing reduced gliding of the median nerve and flexor tendon in CTS patients, particularly in transverse movements. The application of dynamic analysis using the PIV method has potential for use in diagnosis and rehabilitation of CTS.Sep. 2025, Journal of orthopaedic research : official publication of the Orthopaedic Research Society, 43(9) (9), 1673 - 1678, English, International magazineScientific journal

- In idiopathic carpal tunnel syndrome (CTS), fibrosis and thickening of the subsynovial connective tissue (SSCT) increase pressure within the carpal tunnel, resulting in median nerve entrapment. Mitochondrial dysfunction in tissues reportedly leads to senescent cell accumulation and various diseases through reduced adenosine triphosphate (ATP) and excessive reactive oxygen species (ROS) production; however, no reports have linked this to CTS. Therefore, this study aimed to evaluate mitochondrial function in SSCTs of patients with CTS. This study investigated SSCTs obtained during carpal tunnel release surgery in patients with CTS (CTS group) and those obtained during tendon transfer or tendon rupture surgery in patients without CTS (control group) from April 2021 to March 2023 at our hospital. Outcome measures included superoxide dismutase (SOD) activity, gene expression levels, immunofluorescence staining, ATP production assays, and transmission electron microscopy (TEM). p values were calculated using the Mann-Whitney U test. The CTS and control groups included 10 and 5 patients (mean age, 67.8 ± 9.57 and 65.4 ± 9.75 years), respectively. The CTS group exhibited decreased SOD activity (p = 0.026), increased gene expression of mitochondrial biosynthetic factors, and decreased mitochondrial ATP production (p = 0.027). The CTS group showed increased mitochondrial ROS production (p = 0.038) on immunofluorescence and larger mitochondrial area (p = 0.030) and fewer mitochondrial cristae (p = 0.045) on TEM. Multiple mitochondrial function assays suggested mitochondrial dysfunction of SSCTs in the CTS group. STATEMENT OF CLINICAL SIGNIFICANCE: This research provided important information on the histological changes in the subsynovial connective tissue within the carpal tunnel in carpal tunnel syndrome.May 2025, Journal of orthopaedic research : official publication of the Orthopaedic Research Society, 43(5) (5), 1045 - 1053, English, International magazineScientific journal
- This study aims to develop and evaluate a deep learning (DL) model for classifying tendon gliding sounds recorded using digital stethoscopes (Nexteto, ShareMedical, Japan, Nagoya). Specifically, we investigate whether differences in tendon excursion and biomechanics produce distinct acoustic signatures that can be identified through spectrogram analysis and machine learning (ML). Tendon disorders often present characteristic tactile and acoustic features, such as clicking or resistance during movement. In recent years, artificial intelligence (AI) and ML have achieved significant success in medical diagnostics, particularly through pattern recognition in medical imaging. Leveraging these advancements, we recorded tendon gliding sounds from the thumb and index finger in healthy volunteers and transformed these recordings into spectrograms for analysis. Although the sample size was small, we performed classification based on the frequency characteristics of the spectrograms using DL models, achieving high classification accuracy. These findings indicate that AI-based models can accurately distinguish between different tendon sounds and strongly suggest their potential as a non-invasive diagnostic tool for musculoskeletal disorders. This approach could offer a non-invasive diagnostic tool for detecting tendon disorders such as tenosynovitis or carpal tunnel syndrome, potentially aiding early diagnosis and treatment planning.Apr. 2025, Cureus, 17(4) (4), e81790, English, International magazineScientific journal
- Cancer stem cells (CSCs) have been implicated as critical mediators in the progression, chemoresistance and metastatic capabilities of diverse malignancies, including osteosarcoma (OS). The authors have succeeded in generating CSC‑like cells (MG‑OKS) from the OS cell line MG‑63 by transducing defined factors. A significant increase in small proline‑rich protein 1A (SPRR1A) expression, a cross‑linked envelope protein in keratinocytes, was observed in MG‑OKS cells. Therefore, SPRR1A could be involved in tumor initiation, growth and poor OS progression. However, its specific role in OS remains unclear. The present study aimed to evaluate the role of SPRR1A in OS both in vitro and in vivo using MG‑OKS cells. Three experimental groups were established: MG‑OKS cells transfected with SPRR1A small interfering (si)RNA (siMG‑OKS), untransfected MG‑OKS cells and MG‑OKS cells transfected with scrambled siRNA (scMG‑OKS) as controls. SPRR1A expression, morphological changes, cell proliferation and migration were assessed in these groups. RNA sequencing was performed to examine the genetic changes caused by SPRR1A suppression. To evaluate tumorigenicity in vivo, cells from each group were subcutaneously transplanted into the backs of nude mice. Tumor volume and Ki‑67 expression were assessed and compared among the three groups at four weeks post‑transplantation. The siMG‑OKS group exhibited altered cell morphology, reduced cell proliferation and decreased migratory abilities in vitro. RNA sequencing revealed suppression of genes involved in cell adhesion in the siMG‑OKS group. Furthermore, the in vivo tumorigenicity of siMG‑OKS was lower than that of the other two experimental groups. These findings suggest that SPRR1A is one of the key cell adhesion‑related molecules involved in OS progression, potentially serving as a therapeutic target for this refractory tumor. However, further research is needed to fully elucidate the mechanisms by which SPRR1A influences OS pathogenesis and to explore its clinical potential.Feb. 2025, Oncology reports, 53(2) (2), English, International magazineScientific journal
- ABSTRACT Histomorphometry is an important technique in the evaluation of non‐traumatic osteonecrosis of the femoral head (ONFH). Quantification of empty lacunae and pyknotic cells on histological images is the most reliable measure of ONFH pathology, yet it is time and manpower consuming. This study focused on the application of artificial intelligence (AI) technology to tissue image evaluation. The aim of this study is to establish an automated cell counting platform using YOLOv8 as an object detection model on ONFH tissue images and to evaluate and validate its accuracy. From 30 ONFH model rabbits, 270 tissue images were prepared; based on evaluations by three researchers, ground truth labels were created to classify each cell in the image into two classes (osteocytes and empty lacunae) or three classes (osteocytes, pyknotic cells, and empty lacunae). Two and three classes were then annotated on each image. Transfer learning based on annotated data (80% for training and 20% for validation) was performed using YOLOv8n and YOLOv8x with different parameters. To evaluate the detection accuracy of the training model, the mean average precision (mAP (50)) and precision‐recall curve were identified. In addition, the reliability of cell counting by YOLOv8 relative to manual cell counting was evaluated by linear regression analysis using five histological images unused in previous experiments. The mAP (50) for the detection of empty lacunae was 0.868 for the YOLOv8n and 0.883 for the YOLOv8x. The mAP (50) for the three classes was 0.735 for the YOLOv8n model and 0.750 for the YOLOv8x model. The quantification of empty lacunae by automated cell counting obtained in the learning was highly correlated with the manual counting data. The development of an AI‐applied automated cell counting platform will significantly reduce the time and effort of manual cell counting in histological analysis.Wiley, Dec. 2024, Journal of Biomedical Materials Research Part B: Applied Biomaterials, 112(12) (12)Scientific journal
- Background: The medial ulnar collateral ligament (UCL) of the elbow joint is the primary restraint to valgus stress during the throwing motion. The flexor pronator muscles (FPMs) also stabilize the elbow joint against valgus forces; however, assessment of FPM stiffness in baseball players has been limited. Purpose: To use ultrasound shear wave elastography (USWE) to evaluate the change in tissue elasticity of the FPMs due to pitching. Study Designs: Descriptive laboratory study. Methods: Included were 14 healthy male amateur baseball players (mean age, 28.0 ± 2.6 years) who had played intermediate-level high school or college baseball. The tissue elasticity of the flexor digitorum superficialis (FDS) in the superficial layer of the FPMs and the flexor digitorum profundus (FDP) in the deep layer of the FPMs were measured using USWE before, immediately after, and 24 hours after a throwing session of 100 pitches. The intra- and interrater reliability of the measurements were evaluated using the Pearson correlation coefficient and intraclass correlation coefficient (ICC). The elasticity of each muscle was analyzed using repeated-measures analysis of variance followed by post hoc analysis. Results: Reliability of the USWE measurements was good to excellent (intrarater ICCs, 0.78-0.94; interrater ICCs, 0.85-0.96). The mean tissue elasticity values before, immediately after, and 24 hours after pitching were 22.3 ± 4.4, 41.0 ± 13.8, and 38.3 ± 11.2 kPa, respectively, for the FDS and 27.1 ± 5.8, 48.0 ± 22.3, and 29.6 ± 11.5 kPa, respectively, for the FDP. For both the FDS and FDP, elasticity was significantly higher immediately after pitching than before pitching ( P < .001 and P = .0027, respectively). While the elasticity of the FDS at 24 hours after pitching remained significantly higher compared with before pitching ( P = .0011), the elasticity of the FDP at 24 hours decreased to the same level as before pitching ( P = .91). Conclusion: Results using USWE indicated that the elasticity of the FDS did not decrease 24 hours after pitching and remained significantly higher than before pitching, suggesting that it may not be fully functioning as a dynamic stabilizer during this period. Clinical Relevance: Pitching in such a condition may result in greater stress on the UCL and increase the risk of UCL injury.SAGE Publications, Nov. 2024, Orthopaedic Journal of Sports Medicine, 12(11) (11)Scientific journal
- Abstract This study emphasizes the importance of early detection of osteonecrosis of the femoral head (ONFH) in young patients on long‐term glucocorticoid therapy, including those with acute lymphoblastic leukemia, lupus, and other diagnoses. While X‐ray and magnetic resonance imaging (MRI) are standard imaging methods for staging ONFH, MRI can be costly and time‐consuming. The research focuses on utilizing artificial intelligence (AI) to enhance the evaluation of radiographic images for ONFH detection. The study involved analyzing X‐ray and MRI from 102 control hips and 104 ONFH‐affected hips at Association Research Circulation Osseous (ARCO) Stage II and IIIa. We employed transfer learning with the YOLOv8 model for object detection, using 80% of the data for training and 20% for validation, then assessed detection accuracy through mean average precision (mAP) and a precision‐recall curve. Additionally, AI generated synthetic MRI (sMRI) from X‐ray images using a Generative Adversarial Network (GAN) and evaluated their similarity to original MRI. Results showed that the mAP for ONFH detection was 0.923 for the YOLOv8n model and 0.951 for YOLOv8x. The GAN‐generated sMRI exhibited lower image quality compared with originals but maintained potential for lesion assessment. Intrarater reliability among evaluators was high. The findings indicate that AI techniques, particularly YOLOv8 for object detection and GAN for image generation, can effectively assist in ONFH screening, despite some limitations in the generated MRI quality.Wiley, Nov. 2024, Journal of Orthopaedic ResearchScientific journal

- Traditionally, angle measurements have been performed using a goniometer, but the complex motion of shoulder movement has made these measurements intricate. The angle of rotation of the shoulder is particularly difficult to measure from an upright position because of the complicated base and moving axes. In this study, we attempted to estimate the shoulder joint internal/external rotation angle using the combination of pose estimation artificial intelligence (AI) and a machine learning model. Videos of the right shoulder of 10 healthy volunteers (10 males, mean age 37.7 years, mean height 168.3 cm, mean weight 72.7 kg, mean BMI 25.6) were recorded and processed into 10,608 images. Parameters were created using the coordinates measured from the posture estimation AI, and these were used to train the machine learning model. The measured values from the smartphone's angle device were used as the true values to create a machine learning model. When measuring the parameters at each angle, we compared the performance of the machine learning model using both linear regression and Light GBM. When the pose estimation AI was trained using linear regression, a correlation coefficient of 0.971 was achieved, with a mean absolute error (MAE) of 5.778. When trained with Light GBM, the correlation coefficient was 0.999 and the MAE was 0.945. This method enables the estimation of internal and external rotation angles from a direct-facing position. This approach is considered to be valuable for analyzing motor movements during sports and rehabilitation.May 2024, Sensors (Basel, Switzerland), 24(9) (9), English, International magazineScientific journal
- MediaPipe Hand (MediaPipe) is an artificial intelligence (AI)-based pose estimation library. In this study, MediaPipe was combined with four machine learning (ML) models to estimate the rotation angle of the thumb. Videos of the right hands of 15 healthy volunteers were recorded and processed into 9000 images. The rotation angle of the thumb (defined as angle θ from the palmar plane, which is defined as 0°) was measured using an angle measuring device, expressed in a radian system. Angle θ was then estimated by the ML model by using parameters calculated from the hand coordinates detected by MediaPipe. The linear regression model showed a root mean square error (RMSE) of 12.23, a mean absolute error (MAE) of 9.9, and a correlation coefficient of 0.91. The ElasticNet model showed an RMSE of 12.23, an MAE of 9.95, and a correlation coefficient of 0.91; the support vector machine (SVM) model showed an RMSE of 4.7, an MAE of 2.5, and a correlation coefficient of 0.99. The LightGBM model achieved high values: an RMSE of 4.58, an MAE of 2.62, and a correlation coefficient of 0.99. Based on these findings, we concluded that the thumb rotation angle can be estimated with high accuracy by combining MediaPipe and ML.May 2024, Cureus, 16(5) (5), e59657, English, International magazineScientific journal
- BACKGROUND: Postoperative rotator cuff retear after arthroscopic rotator cuff repair (ARCR) is still a major problem. Various risk factors such as age, gender, and tear size have been reported. Recently, magnetic resonance imaging-based stump classification was reported as an index of rotator cuff fragility. Although stump type 3 is reported to have a high retear rate, there are few reports on the risk of postoperative retear based on this classification. Machine learning (ML), an artificial intelligence technique, allows for more flexible predictive models than conventional statistical methods and has been applied to predict clinical outcomes. In this study, we used ML to predict postoperative retear risk after ARCR. METHODS: The retrospective case-control study included 353 patients who underwent surgical treatment for complete rotator cuff tear using the suture-bridge technique. Patients who initially presented with retears and traumatic tears were excluded. In study participants, after the initial tear repair, rotator cuff retears were diagnosed by magnetic resonance imaging; Sugaya classification types IV and V were defined as re-tears. Age, gender, stump classification, tear size, Goutallier classification, presence of diabetes, and hyperlipidemia were used for ML parameters to predict the risk of retear. Using Python's Scikit-learn as an ML library, five different AI models (logistic regression, random forest, AdaBoost, CatBoost, LightGBM) were trained on the existing data, and the prediction models were applied to the test dataset. The performance of these ML models was measured by the area under the receiver operating characteristic curve. Additionally, key features affecting retear were evaluated. RESULTS: The area under the receiver operating characteristic curve for logistic regression was 0.78, random forest 0.82, AdaBoost 0.78, CatBoost 0.83, and LightGBM 0.87, respectively for each model. LightGBM showed the highest score. The important factors for model prediction were age, stump classification, and tear size. CONCLUSIONS: The ML classifier model predicted retears after ARCR with high accuracy, and the AI model showed that the most important characteristics affecting retears were age and imaging findings, including stump classification. This model may be able to predict postoperative rotator cuff retears based on clinical features.Apr. 2024, Journal of shoulder and elbow surgery, 33(4) (4), 815 - 822, English, International magazineScientific journal
- Background and Objectives: Androgen deprivation therapy (ADT) for prostate cancer has greatly improved treatment outcomes. As patient survival rates have increased, reports of decreased bone density and increased bone fractures as side effects of ADT have emerged. The prevalence of osteoporosis in Japanese men was 4.6%. The purpose of this study was to evaluate the effect of osteoporosis treatment in prostate cancer patients who underwent ADT in Japan. Materials and Methods: The subjects were 33 male patients who had undergone ADT for prostate cancer, who were noted to have decreased bone density. Mean age was 76.2 ± 7.7 years (64-87). Medications included vitamin D in one case, bisphosphonates (BP) in 27 cases, and denosumab in five cases. The evaluation method examined the rate of change in bone mineral density (BMD) before osteoporosis treatment and 1 year after. For comparison, a group without osteoporosis treatment intervention (n = 33) was selected, and matched for prostate cancer treatment and age. The rate of change in trabecular bone score (TBS) was also calculated. Results: The percentage changes in BMD before and 1 year after treatment were as follows: lumbar spine, 7.1 ± 5.8% in the treatment group versus -3.9 ± 4.1% in the no treatment group; femoral neck, 5.5 ± 6.2% in the treatment group versus -0.9 ± 3.9% in the no treatment group; total femur, 6.6 ± 6.4% in the treatment group versus the no treatment group which was -1.7 ± 3.2%. In all cases, there was a clear significant difference (p < 0.01). The percent change in TBS was further calculated in the same manner. There was no significant difference between the two groups: +1.7 ± 3.8% in the treated group versus +0.3 ± 4.1% in the untreated group. Conclusions: Osteoporosis treatment in Japanese patients with prostate cancer on ADT therapy was found to significantly increase BMD compared to the untreated group. BP and denosumab were found to be very effective in increasing BMD.Mar. 2024, Medicina (Kaunas, Lithuania), 60(4) (4), English, International magazineScientific journal

- A combination of osteotomy and ligament reconstruction is recommended for posterolateral rotatory instability (PLRI) with large cubitus varus deformities. There is a lack of reports regarding ligament donor selection for ligament reconstruction of PLRI with cubitus varus. Two cases of PLRI with cubitus varus have been described. In case one, a 40-year-old woman presented with left elbow pain. She had a cubitus varus deformity, resulting from a childhood elbow fracture. Radiographs showed an 18-degree cubitus varus deformity. A lateral closing wedge osteotomy and double plate osteosynthesis were performed. The lateral collateral ligament (LCL) was reconstructed with autologous triceps fascia. Postoperative radiographs confirmed correction with 10 degrees of the carrying angle (CA). Bone union at the osteotomy site occurred six months later with excellent results. In case two, a 45-year-old man presented an arm with persistent right elbow instability with cubitus varus deformity. This was due to a childhood supracondylar fracture of the right humerus. Radiographs showed a cubitus varus deformity of 25 degrees on the right. The surgical procedure included a lateral wedge osteotomy, double plate fixation, and LCL reconstruction with autologous triceps fascia. Postoperative radiographs confirmed a corrected CA of 5 degrees. Bone union was achieved at the six-month follow-up with satisfactory results. The use of triceps fascia for LCL reconstruction for PLRI due to cubitus varus would provide a minimally invasive and reasonable treatment option.Feb. 2024, Cureus, 16(2) (2), e54530, English, International magazine
- BACKGROUND: Advanced glycation end products (AGEs) are compounds formed due to aging and diabetes mellitus (DM). They activate NADPH oxidase (NOX) by binding to their receptors, thereby increasing the production of reactive oxygen species (ROS), which cause oxidative stress. In this study, we investigated the effects of AGEs on the tissues of the shoulder joint (such as rotator cuff synovium, and capsule) in patients with DM having rotator cuff tears. METHODS: This study included eight patients with DM who underwent surgical treatment for rotator cuff tears with contracture. The rotator cuff, synovium, and joint capsule were harvested at the time of surgery and evaluated by hematoxylin-eosin staining. Furthermore, immunostaining was used for evaluating AGEs and receptor for AGEs (RAGE), cell activity, ROS, and apoptosis. Quantitative real-time polymerase chain reaction (qPCR) was employed for the cellular evaluation of NOX, interleukins, RAGE, and collagen. RESULTS: The AGEs and RAGE staining as well as the ratio of ROS and apoptosis were in the following order: rotator cuff > joint capsule > synovium. In contrast, the cellular activity was significantly higher in the synovium than in the other regions. The type I collagen expression (as shown by qPCR) as well as the RAGE and NOX expressions were as follows: rotator cuff > joint capsule > synovium. Conversely, the expression of inflammatory cytokines (i.e., IL-6 and IL-1β) was higher in the synovium than in the other regions. CONCLUSIONS: Our study is among the first to evaluate the effects of AGEs on each tissue of the shoulder joint in patients with DM having rotator cuff tears and contractures. The accumulation of AGEs in each tissue of the shoulder joint could reveal the locations affected by DM, which can lead to a better understanding of the pathophysiology of DM-related shoulder diseases.Dec. 2023, Molecular biology reports, 50(12) (12), 10339 - 10349, English, International magazineScientific journal
- BACKGROUND: We previously demonstrated that CD34 + cell transplantation in animals healed intractable fractures via osteogenesis and vasculogenesis; we also demonstrated the safety and efficacy of this cell therapy in an earlier phase I/II clinical trial conducted on seven patients with fracture nonunion. Herein, we present the results of a phase III clinical trial conducted to confirm the results of the previous phase studies using a larger cohort of patients. METHODS: CD34 + cells were mobilized via administration of granulocyte colony-stimulating factor, harvested using leukapheresis, and isolated using magnetic cell sorting. Autologous CD34 + cells were transplanted in 15 patients with tibia nonunion and 10 patients with femur nonunion, who were followed up for 52 weeks post transplantation. The main outcome was a reduction in time to heal the tibia in nonunion patients compared with that in historical control patients. We calculated the required number of patients as 15 based on the results of the phase I/II study. An independent data monitoring committee performed the radiographic assessments. Adverse events and medical device failures were recorded. RESULTS: All fractures healed during the study period. The time to radiological fracture healing was 2.8 times shorter in patients with CD34 + cell transplantation than in the historical control group (hazard ratio: 2.81 and 95% confidence interval 1.16-6.85); moreover, no safety concerns were observed. CONCLUSIONS: Our findings strongly suggest that autologous CD34 + cell transplantation is a novel treatment option for fracture nonunion. TRIAL REGISTRATION: UMIN-CTR, UMIN000022814.

- BACKGROUND: Retear after arthroscopic rotator cuff repair (ARCR) remains a complication of important concern. Few reports have evaluated retear timing and its associated patient characteristics in large cohorts. This study aimed to investigate retear timing and patient characteristics and factors associated with this parameter. METHODS: Of the 638 consecutive shoulders that underwent ARCR from August 2009 to November 2019, shoulders with retear complication within 1 year of surgery were included. Retears were defined as type IV or V of the Sugaya's classification, and magnetic resonance imaging was performed at 6 weeks, 3 months, 6 months, and 1 year after surgery. The distribution of patients with retears at the timing of retears was investigated. In addition, patients with retears were classified into the following two groups: early group with retears occurring at 6 weeks and 3 months postoperatively or late group with retears occurring between 6 months and 1 year postoperatively. Associated factors such as sex, age, tear size, pre and postoperative range of motion, surgical technique, and clinical outcome between the two groups were investigated. RESULTS: The 41 shoulders with retears were divided into four groups: 1) within 6 weeks after surgery (n = 9, 22.0%), 2) 6 weeks-to 3 months after surgery (n = 19, 46.3%), 3) 3-6 months after surgery (n = 11, 26.8%), and 4) 6 months-1 year after surgery (n = 2, 4.9%). In addition, there were significantly larger retear sizes in the Sugaya's classification in the early group compared to the late group (P = .013), while there were significantly more males in the late group compared to the early group (P = .030). CONCLUSION: The highest retear rate after ARCR was observed from 6 weeks to 3 months after surgery, with equivalent rates within 6 weeks and from 3 months to 6 months after surgery.Sep. 2023, Journal of shoulder and elbow surgery, 32(9) (9), 1929 - 1936, English, International magazineScientific journal
- 当院で2021~2022年に上腕骨近位端骨折続発症に対してRSAを施行した7例の成績を報告した。男性1例、女性6例、手術時年齢は平均78.9歳、Boileau分類タイプ1が1例、タイプ3が5例、タイプ4が1例、初回骨折からRSAまでの期間は平均30.4ヵ月であった。JOAスコアは術前平均39.7点から術後78.9点に改善し、UCLAスコアは術前平均8点から術後24.1点に改善、Constantスコアは術前平均15.1点から術後42点に改善した。自動可動域は屈曲が術前平均34.3°から術後91.7°に改善し、外転が術前平均31.4°から術後95°に改善、外旋が術前平均0.7°から術後33.3°に改善した。これらの成績から上腕骨近位端骨折続発症に対してRSAは有用と考えられたが、過去に報告された腱板断裂や変形性肩関節症に対するRSAの成績と比較すると術後可動域が不良であり、成績向上のためには結節部の保護や解剖学的な修復が必要と考えられた。(一社)中部日本整形外科災害外科学会, Sep. 2023, 中部日本整形外科災害外科学会雑誌, 66(5) (5), 727 - 728, Japanese
- Substantial advancements in markerless motion capture accuracy exist, but discrepancies persist when measuring joint angles compared to those taken with a goniometer. This study integrates machine learning techniques with markerless motion capture, with an aim to enhance this accuracy. Two artificial intelligence-based libraries-MediaPipe and LightGBM-were employed in executing markerless motion capture and shoulder abduction angle estimation. The motion of ten healthy volunteers was captured using smartphone cameras with right shoulder abduction angles ranging from 10° to 160°. The cameras were set diagonally at 45°, 30°, 15°, 0°, -15°, or -30° relative to the participant situated at a distance of 3 m. To estimate the abduction angle, machine learning models were developed considering the angle data from the goniometer as the ground truth. The model performance was evaluated using the coefficient of determination R2 and mean absolute percentage error, which were 0.988 and 1.539%, respectively, for the trained model. This approach could estimate the shoulder abduction angle, even if the camera was positioned diagonally with respect to the object. Thus, the proposed models can be utilized for the real-time estimation of shoulder motion during rehabilitation or sports motion.Jul. 2023, Sensors (Basel, Switzerland), 23(14) (14), English, International magazineScientific journal
- The coracohumeral ligament (CHL) is related to the range of motion of the shoulder joint. The evaluation of the CHL using ultrasonography (US) has been reported on the elastic modulus and thickness of the CHL, but no dynamic evaluation method has been established. We aimed to quantify the movement of the CHL by applying Particle Image Velocimetry (PIV), a technique used in the field of fluid engineering, to cases of shoulder contracture using the US. The subjects were eight patients, with 16 shoulders. The coracoid process was identified from the body surface, and a long-axis US image of the CHL parallel to the subscapularis tendon was drawn. The shoulder joint was moved from 0 degrees of internal/external rotation to 60 degrees of internal rotation at a rhythm of one reciprocation every 2 s. The velocity of the CHL movement was quantified by the PIV method. The mean magnitude velocity of CHL was significantly faster on the healthy side. The maximum magnitude velocity was significantly faster on the healthy side. The results suggest that the PIV method is helpful as a dynamic evaluation method, and in patients with shoulder contracture, the CHL velocity was significantly decreased.Apr. 2023, Sensors (Basel, Switzerland), 23(8) (8), English, International magazineScientific journal
- Advanced glycation end-products (AGEs) play a critical supportive role during musculoskeletal disorders via glycosylation and oxidative stress. Though apocynin, identified as a potent and selective inhibitor of NADPH oxidase, has been reported to be involved in pathogen-induced reactive oxygen species (ROS), its role in age-related rotator cuff degeneration has not been well clarified. Therefore, this study aims to evaluate the in vitro effects of apocynin on human rotator cuff-derived cells. Twelve patients with rotator cuff tears (RCTs) participated in the study. Supraspinatus tendons from patients with RCTs were collected and cultured. After the preparation of RC-derived cells, they were divided into four groups (control group, control + apocynin group, AGEs group, AGEs + apocynin group), and gene marker expression, cell viability, and intracellular ROS production were evaluated. The gene expression of NOX, IL-6, and the receptor for AGEs (RAGE) was significantly decreased by apocynin. We also examined the effect of apocynin in vitro. The results showed that ROS induction and increasing apoptotic cells after treatment of AGEs were significantly decreased, and cell viability increased considerably. These results suggest that apocynin can effectively reduce AGE-induced oxidative stress by inhibiting NOX activation. Thus, apocynin is a potential prodrug in preventing degenerative changes of the rotor cuff.Apr. 2023, Current issues in molecular biology, 45(4) (4), 3434 - 3445, English, International magazineScientific journal
- PURPOSE: Arthroscopic repair is performed for fovea injuries of the triangular fibrocartilage complex (TFCC) when instability of the distal radioulnar joint results in pain, decreased grip strength, and mechanical symptoms. During TFCC repair, reconstruction of its attachment to the fovea is important. Nonabsorbent suture tapes have gained attention for ligament repair in the trapeziometacarpal joint, scapholunate ligament, and thumb metacarpophalangeal ligament. However, there are no reports of TFCC repair using suture tapes. We evaluated the early postoperative results of this approach. METHODS: Participants underwent arthroscopic suture tape repair of foveal TFCC tears and were observed for more than 1 year. All repairs were performed using suture tapes and an outside-in technique with a bone tunnel from the ulnar shaft to the fovea. The postoperative complications, postoperative wrist range of motion, grip strength, and the Modified Mayo Score were evaluated. RESULTS: Arthroscopic repair with a suture tape was performed for 20 hands using the outside-in technique. The ranges of motion for the operated and nonoperated hands were comparable 1 year after surgery (pronation, 84° ± 4°; supination, 83° ± 4°). The mean grip strength improved from 65% ± 13% before surgery to 89% ± 9% after a year. The mean Modified Mayo Score improved from 58 ± 11 before surgery to 91 ± 8 after a year. Postoperative complications included abnormal sensation of the dorsal ulnar side in 2 hands. CONCLUSIONS: After using a suture tape to attach the TFCC to the fovea, satisfactory function was achieved in the early postoperative period with grip strength restoration. For the repair of foveal TFCC tears, attachment to the ulnar fovea is important, and repair by a suture tape may be useful.

- The diagnosis of osteoporosis is made by measuring bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA). Machine learning, one of the artificial intelligence methods, was used to predict low BMD without using DXA in elderly women. Medical records from 2541 females who visited the osteoporosis clinic were used in this study. As hyperparameters for machine learning, patient age, body mass index (BMI), and blood test data were used. As machine learning models, logistic regression, decision tree, random forest, gradient boosting trees, and lightGBM were used. Each model was trained to classify and predict low-BMD patients. The model performance was compared using a confusion matrix. The accuracy of each trained model was 0.772 in logistic regression, 0.739 in the decision tree, 0.775 in the random forest, 0.800 in gradient boosting, and 0.834 in lightGBM. The area under the curve (AUC) was 0.595 in the decision tree, 0.673 in logistic regression, 0.699 in the random forest, 0.840 in gradient boosting, and 0.961, which was the highest, in the lightGBM model. Important features were BMI, age, and the number of platelets. Shapley additive explanation scores in the lightGBM model showed that BMI, age, and ALT were ranked as important features. Among several machine learning models, the lightGBM model showed the best performance in the present research.Feb. 2023, Bioengineering (Basel, Switzerland), 10(3) (3), English, International magazineScientific journal
- BACKGROUND: Medical screening using ultrasonography (US) has been performed on young baseball players for early detection of osteochondritis dissecans (OCD) of the humeral capitellum. Deep learning (DL) and artificial intelligence (AI) techniques are widely adopted in the medical imaging research field. PURPOSE/HYPOTHESIS: The purpose of this study was to calculate the diagnostic accuracy using DL for US images of OCD. We hypothesized that using DL for US imaging would improve the prediction accuracy of OCD. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 2. METHODS: A total of 40 elbows (mean age of patients, 12.1 years) that were suspected of having OCD at a medical checkup and later confirmed by radiographs and magnetic resonance imaging were included in the study. The affected elbows were used as the OCD group and the contralateral elbows as the control group. From US videos, 100 images per elbow were captured from different angles, and 4000 images of the elbows were prepared for both groups. Of these, 80% were randomly selected by DL models and used as training data; the remaining were used as test data. Transfer learning was conducted using 3 pretrained DL models. The confusion matrix and the area under the receiver operating characteristic curve (AUC) were used to evaluate the model, and the visualization of the areas deemed important by the DL models was also performed. Furthermore, OCD regions were detected using an automatic image recognition model based on DL. RESULTS: Classification of the OCD image by the DL model was performed; the best accuracy score was 0.87; the recall was 1.00. AUC was high for all DL models. Visualization of important features showed that AI predicted the presence of OCD by focusing on the irregularity or discontinuity of the surface of subchondral bone. In the detection of OCD task, the mean average precision was 0.83. CONCLUSION: The DL on US images identified OCD with high accuracy. The important features detected by the DL models correspond to the areas used by clinicians in screening the US images. The OCD was also detected with high accuracy using the object detection model. The AI model may be used in medical screening for OCD.Feb. 2023, The American journal of sports medicine, 51(2) (2), 358 - 366, English, International magazineScientific journal

- Purpose: One-stage arthroscopic rotator cuff repair with manipulation has been recently performed for rotator cuff tears with shoulder stiffness, whereas some patients require capsular release due to severe stiffness that is difficult to treat with manipulation. The purpose of this study was to analyze patient backgrounds and related factors of success or failure of manipulation alone for the treatment of shoulder stiffness associated with rotator cuff tears. Methods: This study included 64 patients with rotator cuff tears and shoulder stiffness who underwent arthroscopic rotator cuff repair with manipulation alone or with manipulation and capsular release of the glenohumeral joint at our institution between January 2015 and September 2019. The patients were divided into two groups: those whose shoulder stiffness could be improved by manipulation alone (Manipulation group) and those whose stiffness could not be improved by manipulation alone and required capsular release (Capsular release addition group). Analysis was performed between the two groups regarding patient backgrounds and related factors, including rotator cuff tear morphology and range of motions pre- and postoperatively. Results: Exactly 45 patients and 19 patients were included in Manipulation group and Capsular release addition group, respectively. A comparison between the two groups showed that patient age (p = 0.0040), sex (p = 0.0005), and injury due to trauma (p = 0.0018) were significantly related to the success or failure of manipulation alone. Multivariate logistic regression analysis on these three factors showed that sex (odds ratio, 5.5; p = 0.048) was significantly associated with the success or failure of manipulation alone. In both groups, the passive ROM of all patients improved at the last postoperative follow-up compared to their pre-operative values (p < 0.001), except for internal rotation in the Capsular release addition group (p = 0.49). Conclusion: Young male patients who have shoulder stiffness associated with rotator cuff tears should be considered for arthroscopic capsular release rather than manipulation.Dec. 2022, Journal of clinical medicine, 11(23) (23), English, International magazineScientific journal
- BACKGROUND: Large and massive rotator cuff tears are challenging for surgeons because of postoperative complications such as repaired site retears. Recently, collagen extracted from fish scales has gained more attention because fish byproducts are considered a safer collagen source than other animal-derived scaffolds. This study aimed to evaluate the biological efficacy of tilapia scale-derived collagen scaffolds for rotator cuff repair in rat models. METHODS: The infraspinatus tendon was resected from the greater tuberosity of Sprague-Dawley rats. In the control group, the tendon edge was sutured directly to the humeral head. In the augmentation group, the repaired site was augmented with a tilapia scale-derived collagen scaffold. Histologic examinations were performed at 2 and 4 weeks postoperatively via safranin O and immunofluorescence staining (isolectin B4 and type II collagen) in the bone-tendon junction. For mechanical analysis, the ultimate failure load of the tendon-humeral head complex was evaluated at 6 weeks postoperatively. RESULTS: During safranin O staining, the repaired enthesis demonstrated greater proteoglycan staining in the augmentation group than in the control group at 4 weeks postoperatively. Compared to controls, the augmentation group had significantly higher vascular staining with isolectin B4 at 2 and 4 weeks postoperatively, type II collagen expression at 4 weeks postoperatively, and ultimate failure load at 6 weeks postoperatively. CONCLUSION: Augmentation therapy using tilapia scale-derived type I collagen scaffolds promoted angiogenesis and fibrocartilage regeneration at the enthesis and provided higher mechanical strength than controls.Dec. 2022, Journal of shoulder and elbow surgery, 31(12) (12), 2629 - 2637, English, International magazineScientific journal
- BACKGROUND: Injury to the ulnar collateral ligament (UCL) of the elbow can cause chronic pain and loss of throwing ability. Ultrasonic shear wave elastography (SWE) is a new imaging method that can be used for quantitative assessment of tissue elasticity. PURPOSE: To evaluate the properties of the UCL in professional baseball players using SWE. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: This study included 35 professional baseball players (mean age, 23.0 years) without elbow injuries. Both elbows of each player were examined using ultrasound, and comparisons between the dominant and nondominant arms were conducted. The thickness of the anterior bundle of the UCL at its midportion was measured in the resting position on ultrasound. We also measured the difference in the ulnohumeral joint space with and without gravity stress on the forearm. Tissue elasticity was evaluated using a built-in software program. The relationship between UCL elasticity and ultrasound findings was analyzed using the Pearson correlation coefficient. RESULTS: The mean ± SD thickness of the UCL was significantly greater in the dominant arm versus the nondominant arm (6.0 ± 1.4 vs 5.3 ± 1.3 mm; P = .004). The mean joint space difference was significantly wider in the dominant arm as compared with the nondominant arm (0.81 ± 0.42 vs 0.52 ± 0.31 mm; P = .002), and the mean UCL elasticity was lower in the dominant arm than in the nondominant arm (34.9 ± 11.6 vs 43.3 ± 10.6 kPa; P = .002). UCL elasticity was negatively correlated with UCL thickness (r = -0.27; P = .02) and joint space difference (r = -0.34; P = .003). CONCLUSION: In professional baseball players, the elbow UCL of the dominant arm demonstrated increased thickness, with a larger joint space gap on gravity stress and lower elasticity in SWE as compared with the nondominant arm. Greater medial joint laxity can be predicted by assessing the elasticity of the UCL using SWE.Dec. 2022, Orthopaedic journal of sports medicine, 10(12) (12), 23259671221138134 - 23259671221138134, English, International magazineScientific journal
- INTRODUCTION: The introduction of tyrosine kinase inhibitors has revolutionized treatment strategies for metastatic renal cell carcinoma (RCC) and has improved survival rates. The number of patients with bone metastases from RCC requiring surgery will increase as survival rates improve. However, there is insufficient evidence to standardize the treatment of bone metastases after the introduction of targeted therapy for metastatic RCC. We aimed to determine the outcomes of palliative surgical treatment of bone metastases in the extremities of patients with metastatic RCC. MATERIALS AND METHODS: We retrospectively reviewed 26 lesions from 17 patients who underwent surgery for extremity and acetabular bone metastases and were treated with targeted therapies for advanced RCC between 2008 and 2020. The median follow-up duration was 19 months (range, 4-76). We assessed the patients' activities of daily living, quality of life, and pain and analyzed their postoperative values relative to preoperative values. Postoperative overall survival (OS), local progression-free survival (LPFS), and the factors affecting them were evaluated using the Kaplan-Meier method and log-rank test. RESULTS: The 5-year OS and LPFS rates were 39.5% and 65.6%, respectively. The factors affecting OS were sex, Katagiri score, visceral metastases, and preoperative targeted therapy, while the factors affecting LPFS were pathologic fractures and surgical technique. CONCLUSION: In this study, the postoperative outcomes of palliative surgery for bone metastases from metastatic RCC were good. We suggest that systemic treatment should be prioritized over local control for advanced bone metastasis in RCC and surgery before pathological fracture should be performed for local control.Nov. 2022, European journal of surgical oncology : the journal of the European Society of Surgical Oncology and the British Association of Surgical Oncology, 49(5) (5), 928 - 933, English, International magazineScientific journal
- Ewing sarcoma (ES) is an aggressive primary malignant bone tumor that predominantly affects children and young adults. Multimodal treatment approaches have markedly improved the survival of patients with localized ES. However, local recurrence and distant metastasis following curative therapies remain a main concern for patients with ES. Recent studies have suggested that slow‑cycling cells (SCCs) are associated with tumor progression, local recurrence and distant metastasis in various types of cancers. According to the results of these studies, it was hypothesized that SCCs may play a critical role in tumor progression, chemoresistance and local/distal recurrence in patients with ES. The present study applied a label‑retaining system using carboxyfluorescein diacetate succinimidyl ester (CFSE) to identify and isolate SCCs in ES cell lines. In addition, the properties of SCCs, including sphere formation ability, cell cycle distribution and chemoresistance, in comparison with non‑SCCs were investigated. RNA sequencing also revealed several upregulated genes in SCCs as compared with non‑SCCs; the identified genes not only inhibited cell cycle progression, but also promoted the malignant properties of SCCs. On the whole, the present study successfully identified SCCs in ES cells through a label‑retaining system using CFSE. Moreover, to the best of our knowledge, the present study is the first to describe the characteristic properties of SCCs in ES. The findings of this study, if confirmed, may prove to be useful in elucidating the underlying molecular mechanisms and identifying effective therapeutic targets for ES.Nov. 2022, International journal of oncology, 61(5) (5), English, International magazineScientific journal
- The subsheath of the extensor carpi ulnaris (ECU) tendon, a component of the triangular fibrocartilage complex (TFCC), is particularly important as it dynamically stabilizes the distal radioulnar joint. However, the relationship between TFCC injury and ECU dynamics remains unclear. This study aimed to analyze ECU movement and morphology using ultrasonography (US) images. Twenty wrists of patients with TFCC injury, who underwent TFCC repair, were included in the injury group, and 20 wrists of healthy volunteers were in the control group. For static image analysis, curvature and linearity ratios of the ECU in US long-axis images captured during radioulnar deviation were analyzed. For dynamic analysis of the ECU, the wrist was moved from radial deviation to ulnar deviation at a constant speed, and the velocity of the tendon was analyzed using particle image velocimetry. The static analysis showed that the ECU tendon was more curved in ulnar deviation in the injury group than in the control group, and the dynamic analysis showed that only vertical velocity toward the deep side during ulnar deviation was higher in the injury group. These results suggest that TFCC injury caused ECU curvature during ulnar deviation and increased the vertical velocity of the ECU during wrist deviation.Oct. 2022, Sensors (Basel, Switzerland), 22(21) (21), English, International magazineScientific journal
- Background: We aimed to evaluate the efficacy of abductor pollicis longus (APL) suspension arthroplasty with trapeziectomy combined with first and second metacarpal fixation using suture button device. Methods: Thirteen patients (14 thumbs) who underwent APL suspension arthroplasty combined with suture button device for osteoarthritis of the carpometacarpal joint of the thumb (Eaton grade III: 6 and IV: 8 thumbs) at our institution between 2015 and 2019 and were followed up for more than 24 months were included in the study. Preoperative and postoperative range of motion (ROM) of radial and palmar abduction, grip and key pinch strength, visual analog scale (VAS) scores for pain, and the trapezial space ratio (TSR) on radiographic images before and after surgery were statistically examined. Results: The mean age of the patients was 59.6 ± 8.1 years, and the mean follow-up period was 45.4 ± 12.2 months. While grip and pinch strength did not significantly change between preoperative and final follow-up measurements, the ROM of radial and palmar abduction and the VAS score at the latest follow-up were significantly better than the preoperative values ( P < .05). The mean TSR immediately after surgery and at the latest follow-up was 0.28 ± 0.089 and 0.22 ± 0.084, respectively, indicating a mean reduction rate of 23.3 ± 15.2%. Conclusions: This surgical technique showed significant improvement in the ROM of radial and palmar abduction and the VAS score for pain, and the combined fixation of the first and second metacarpals with suture button device suppressed the subsidence of the first metacarpal.SAGE Publications, Sep. 2022, HAND, 19(3) (3), 419 - 425Scientific journal
- BACKGROUND: Advanced glycation end products (AGEs) are end products of protein glycation that bind to the receptor for AGEs (RAGE) and activate nicotinamide adenine dinucleotide phosphate oxidase (NOX), resulting in increased oxidative stress and rotator cuff fragility. Stump classification using the signal intensity ratio of the tendon rupture site to the deltoid muscle in the coronal view of T2-weighted fat-suppressed magnetic resonance imaging (MRI) scans is an indicator of clinical outcomes after rotator cuff repair surgery. Comparing the signal intensities of the deltoid (D) and rotator cuff tears (C), Ishitani et al. classified C/D <0.8 as type 1, 0.8 to 1.3 as type 2, and >1.3 as type 3. HYPOTHESIS/PURPOSE: It was hypothesized that the oxidative stress and collagen degeneration that occur in the rotator cuff due to accumulation of AGEs can be assessed on MRI scans (stump classification). Therefore, this study aimed to compare AGE-related factors in the rotator cuff tear site tissues based on stump classification. STUDY DESIGN: Descriptive laboratory study. METHODS: The authors included 30 patients (11 with type 1, 9 with type 2, and 10 with type 3; mean age, 62.3 years) who underwent surgery for complete rotator cuff tears at our hospital. Tendon tissue was harvested from the torn rotator cuff site during surgery for tissue and cell evaluation. RESULTS: There was no significant difference in the mean age according to stump classification. The number of patients with diabetes was significantly larger in type 3 than in the other types (P < .05). Tissue evaluation showed significantly higher expression of AGE and RAGE staining in type 3 than in the other types (~6.7-fold; P < .01). Cell evaluation showed that the expression rates of reactive oxygen species and apoptosis were significantly higher in type 3 than in the other types (~4.3-fold; P < .01). Gene expression by real-time polymerase chain reaction showed significantly higher RAGE (~5.1-fold), NOX (~5.3-fold), and IL (~3.0-fold) in type 3 than in the other types (P < .05). CONCLUSION: Stump classification type 3 exhibited the highest accumulation of AGEs and the highest oxidative stress and apoptosis, suggesting a high degree of degeneration and inflammation. Imaging based on stump classification reflects the degeneration and fragility of the torn rotator cuff site. CLINICAL RELEVANCE: This study provides evidence of a relationship between stump classification, which reflects rotator cuff fragility on MRI, and pathologies related to advanced glycation end products.Apr. 2022, The American journal of sports medicine, 3635465221090649 - 3635465221090649, English, International magazineScientific journal
- PURPOSE: To calculate the diagnostic accuracy from the confusion matrix using deep learning (DL) on ultrasound (US) images of Palmer 1B triangular fibrocartilage complex (TFCC) injury. METHODS: Twenty-nine wrists of 15 healthy volunteers (11 men; mean age, 34.9 years ± 9.7) (control group) and 20 wrists of 17 patients (11 men; mean age 41.0 years ± 12.2) with TFCC injury (Palmer type IB) (injury group) were included in the study. The diagnosis of Palmer 1B TFCC injury was made using magnetic resonance imaging, computed tomography arthrography, and intraoperative arthroscopic findings. In total, 2,000 images were provided to each group, 80% of which were randomly selected by AI and used as training data; the remaining data were used as test data. Transfer learning was conducted using a pretrained 3 separate models (GoogLeNet, ResNet50, ResNet101). Model evaluation was performed using a confusion matrix. The area under a receiver operating characteristic curve was also calculated. The occlusion sensitivity was used to visualize the important features. RESULTS: For the prediction of TFCC injury by the DL model, the best score of accuracy was 0.85 in GoogLeNet, a recall was 1.0 in ResNet50 and ResNet101, and a specificity was 0.78 in GoogLeNet. In predicting the TFCC injury for the test data, the best score of the AUC was 0.97 on ResNet101. Visualization of important features showed that AI predicted the presence of injury by focusing on the morphology of the articular disc. CONCLUSIONS: US images using the DL model predicted Palmer 1B TFCC injury with high accuracy, with the best scores of 0.85 for accuracy on GoogLeNet, 1.00 for sensitivity on ResNet50 and ResNet101, and 0.78 for specificity on GoogLeNet. The use of DL for US imaging of Palmer 1B TFCC injury predicted the injury as well as magnetic resonance imaging and computed tomography arthrography LEVEL OF EVIDENCE: IV; retrospective case series study.Apr. 2022, Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association, English, International magazineScientific journal
- Most shoulder rotator cuff tears (RCTs) are caused by non-traumatic age-related rotator cuff degeneration, of which hyperglycemia is a risk factor due to its glycation reaction and oxidative stress. We aimed to identify the influence of diabetes-induced glycation and oxidative stress in patients with non-traumatic shoulder RCTs. Twenty patients, aged over 50 years, with non-traumatic shoulder RCTs participated in this study. Patients with a history of diabetes mellitus or preoperative HbA1c ≥ 6.5% were assigned to the diabetic group (n = 10), and the rest to the non-diabetic group (n = 10). Cell proliferation; expression of genes related to oxidative stress, glycation reaction, inflammation, and collagen; intracellular reactive oxygen species (ROS) levels; and apoptosis rates were analyzed. The diabetic group had significantly lower cell proliferation than the non-diabetic group. In the diabetic group, the mRNA expression levels of NOX1, NOX4, IL6, RAGE, type III collagen, MMP2, TIMP1, and TIMP2 were significantly higher; type I collagen expression was significantly lower; and the rate of ROS-positive cells and apoptotic cells, as well as the expression of advanced glycation end-products (AGEs) and the receptor for AGEs (RAGE), was significantly higher. In conclusion, hyperglycemia caused by diabetes mellitus increased AGE and RAGE expression, and led to increased NOX expression, ROS production, and apoptosis in the human rotator cuff. This provides scope to find a preventive treatment for non-traumatic RCTs by inhibiting glycation and oxidative stress.Apr. 2022, Antioxidants (Basel, Switzerland), 11(4) (4), English, International magazineScientific journal
- BACKGROUND: Most degenerative rotator cuff tears (RCTs) are associated with a limited range of motion (ROM) of the shoulder joint. Additionally, patients with diabetes mellitus (DM) show a higher frequency of limited ROM. Recently, advanced glycation end products (AGEs) of proteins have been observed to cause tissue fibrosis, primarily through abnormal collagen cross-linking and oxidative stress. In this study, we investigated the effect of AGEs on ROM limitation in the shoulder capsule and its relationship with DM in the patients with RCTs. METHODS: Sixteen patients (eight in the DM and non-DM groups) who underwent arthroscopic surgery for RCT with limited shoulder ROM were included in this study. AGE-related pathologies in both groups were compared, and the relationship between AGE accumulation and shoulder joint ROM was evaluated. Shoulder capsule tissue was harvested and subjected to histological and in vitro evaluation. RESULTS: The DM group displayed high levels of AGEs and reactive oxygen species (ROS), and reduced cell viability. There was a significant positive correlation between ROS expression, apoptosis, and preoperative hemoglobin A1c. ROS expression, apoptosis, and ROM of the shoulder joint showed a negative correlation. The NADPH oxidase (NOX) expression and collagen III/I ratio were significantly higher in the DM group than in the non-DM group. CONCLUSIONS: The DM group showed significant AGEs deposition in the shoulder capsule. Additionally, there was a significant association between AGEs and ROM limitation. Collectively, the findings suggest that the oxidative stress induced by AGEs deposition, which leads to fibrosis and local inflammation, might contribute to the limited ROM of the shoulder joint in patients with RCTs accompanied by DM.Mar. 2022, BMC musculoskeletal disorders, 23(1) (1), 271 - 271, English, International magazineScientific journal
- BACKGROUND: A link between tendinopathy and oxidative stress has been recently reported. Nicotinamide mononucleotide (NMN) is a precursor of nicotinamide adenine dinucleotide, which plays an important role in cell redox homeostasis. The aim of this study was to evaluate the antioxidant effect of NMN on tendinopathy in vitro and in vivo. METHODS: Tenocytes from healthy Sprague-Dawley rats were cultured in regular glucose (RG) and high-glucose (HG) conditions with or without NMN, and were divided into four groups: RG NMN(-), RG NMN(+), HG NMN(-), and HG NMN(+). Cell viability, reactive oxygen species (ROS) accumulation, apoptotic rate, and mRNA expression of nicotinamide adenine dinucleotide phosphate oxidase (NOX)1, NOX4, interleukin (IL)6, sirtuin (SIRT)1, and SIRT6 were investigated. In addition, rats with collagenase-induced tendinopathy were treated with or without NMN. Immunostaining of NOX1 and NOX4; mRNA expression of SIRT1, SIRT6, and IL6; and superoxide dismutase (SOD) activity measurements in the Achilles tendon were performed. RESULTS: NMN increased the expression of SIRT1 and SIRT6 in rat tenocytes, but decreased the levels of NOX1, NOX4, IL6, ROS, and apoptosis. In Achilles tendons with collagenase-induced tendinopathy, NMN increased the mRNA expression of SIRT1 and SIRT6, as well as SOD activity; while suppressing protein expression of NOX1 and NOX4, and mRNA expression of IL6. CONCLUSION: The in vitro and in vivo results of this study show that NMN exerts an antioxidant effect on tendinopathy by promoting the expression of SIRT while inhibiting that of NOX.Mar. 2022, BMC musculoskeletal disorders, 23(1) (1), 249 - 249, English, International magazineScientific journal
- Although electromyography is the routine diagnostic method for cubital tunnel syndrome (CuTS), imaging diagnosis by measuring cross-sectional area (CSA) with ultrasonography (US) has also been attempted in recent years. In this study, deep learning (DL), an artificial intelligence (AI) method, was used on US images, and its diagnostic performance for detecting CuTS was investigated. Elbow images of 30 healthy volunteers and 30 patients diagnosed with CuTS were used. Three thousand US images were prepared per each group to visualize the short axis of the ulnar nerve. Transfer learning was performed on 5000 randomly selected training images using three pre-trained models, and the remaining images were used for testing. The model was evaluated by analyzing a confusion matrix and the area under the receiver operating characteristic curve. Occlusion sensitivity and locally interpretable model-agnostic explanations were used to visualize the features deemed important by the AI. The highest score had an accuracy of 0.90, a precision of 0.86, a recall of 1.00, and an F-measure of 0.92. Visualization results show that the DL models focused on the epineurium of the ulnar nerve and the surrounding soft tissue. The proposed technique enables the accurate prediction of CuTS without the need to measure CSA.Mar. 2022, Diagnostics (Basel, Switzerland), 12(3) (3), English, International magazineScientific journal

- Both acromioclavicular joint (ACJ) cysts and hemarthrosis of the shoulder are rare conditions of massive rotator cuff tear that eventually lead to cuff tear arthropathy. We herein report the first case of a patient with co-occurring ACJ cyst and hemarthrosis of the shoulder. An 80-year-old right-hand-dominant man presented to our outpatient department with a six-month history of repeatable right shoulder pain and swelling. Clinical examination revealed a 5 x 5 x 5 cm elastic hard or hard shoulder lump overlying the ACJ on skin with subcutaneous bleeding and swelling of the shoulder. Shoulder pain at rest and a fully reduced active range of motion (ROM), particularly in flexion and abduction, were also noted. Radiographs demonstrated moderate degeneration of the glenohumeral joint including a bone cyst of the humeral head. Magnetic resonance imaging (MRI) revealed a massive rotator cuff tear with atrophy of the supraspinatus, infraspinatus, and subscapularis muscles. The T2-weighted MRI images showed that the cyst was in direct contact with the markedly degenerated glenohumeral joint. Based on these findings, the patient was diagnosed with massive rotator cuff tear with ACJ cyst and hemarthrosis of the shoulder. The patient underwent distal clavicle resection and reverse total shoulder arthroplasty (RSA). At 12-month follow-up, the patient showed no pain symptoms, no recurrence of the cyst, and excellent ROM. We experienced a very rare case of ACJ cyst and hemarthrosis of the shoulder occurring simultaneously with rotator cuff tear arthropathy. This report is very valuable in that it suggests that RSA is useful for both ACJ cysts and hemarthrosis of the shoulders associated with rotator cuff tear arthropathy.Mar. 2022, Cureus, 14(3) (3), e23353, English, International magazine
- This article aims to evaluate the usefulness of ultrasonography for the measurement of thenar muscles in carpal tunnel syndrome (CTS). A total of 85 patients with CTS who had a carpal tunnel release procedure were included in this study. The transducer was applied onto the palmar surface of the hand perpendicularly to the longitudinal axis of the first metacarpal bone. Thenar atrophy was evaluated visually and classified using the visual grading scale. A nerve conduction test was performed and classified according to the electrophysiological severity scale. This technique is more precise than visual evaluation because it is a quantitative assessment.Feb. 2022, Hand clinics, 38(1) (1), 55 - 58, English, International magazineScientific journal
- BACKGROUND: While the precise measurement of the range of motion (ROM) of the elbow joint is important for clinical assessment and rehabilitation, problems include low accuracy and reproducibility in goniometer measurements due to the influence of soft tissue. The purpose of this study was to validate elbow joint motion analysis using a three-dimensional electromagnetic sensor system (EMS). METHODS: The accuracy and reproducibility of the EMS system were evaluated at four angles (0°, 45°, 90°, and 135°) using a model bone of the humerus and forearm. In addition, the maximum extension and maximum flexion of six elbows of six healthy volunteers were assessed by radiographic and EMS measurements. Accuracy was assessed by calculating the mean value of the measurement angle, standard deviation, Pearson's correlation coefficient, and the Bland-Altman method. Reproducibility was assessed by calculating the intra-rater and inter-rater reliabilities using intraclass correlation coefficients. RESULTS: In the model bone evaluation, the mean angles of the EMS measurement were 1.2° ± 2.0°, 45.4° ± 2.1°, 91.7° ± 2.4°, and 134.6° ± 2.7° at 0°, 45°, 90°, and 135°, respectively. In the in vivo evaluation, the elbow angles at the maximum extension with the EMS and radiographic angles were 4.7° ± 3.0° and 2.7° ± 2.0°, respectively, and the angles at maximum flexion were 131.8° ± 13.0° and 130.8° ± 4.5°, respectively. There were statistically significant correlations between the EMS and radiographic measurements; the Bland-Altman plots indicated that the two methods were almost in agreement for both extension and flexion. CONCLUSIONS: This method of measuring ROM of the elbow joint using EMS showed high accuracy, reliability, and reproducibility. The current results demonstrated the possibility of using the electromagnetic system to provide an accurate evaluation of the elbow joint in clinical settings.Jan. 2022, Journal of orthopaedic surgery and research, 17(1) (1), 60 - 60, English, International magazineScientific journal
- Tendon rupture and nerve injury cause fatty infiltration of the skeletal muscle, and the adipokines secreted from the infiltrated adipocytes are known to contribute to chronic inflammation. Therefore, in this study, we evaluated the effects of the adipokines on chronic inflammation using a rat sciatic nerve-crushed injury model. In vitro and in vivo experiments showed that the expression of adiponectin was decreased (0.3-fold) and the expression of Il6 (~ 3.8-fold) and Tnf (~ 6.2-fold) was increased in the nerve-crushed group compared to that in the control group. It was also observed that the administration of an adiponectin receptor agonist decreased the levels of Il6 (0.38-fold) and Tnf (0.28-fold) and improved cellular viability (~ 1.9-fold) in vitro. Additionally, in the fatty infiltrated skeletal muscle, low adiponectin levels were found to be associated with chronic inflammation. Therefore, the local administration of adiponectin receptor agonists would prevent chronic inflammation.Jan. 2022, Scientific reports, 12(1) (1), 1557 - 1557, English, International magazineScientific journal
- The triangular fibrocartilage complex (TFCC) is a significant stabilizer of the distal radioulnar joint. Diagnosing TFCC injury is currently difficult, but ultrasonography (US) has emerged as a low-cost, minimally invasive diagnostic tool. We aimed to quantitatively analyze TFCC by performing motion analysis by using US. Twelve healthy volunteers, comprising 24 wrists (control group), and 15 patients with TFCC Palmer type 1B injuries (injury group) participated. The US transducer was positioned between the ulnar styloid process and triquetrum and was tilted ulnarly 30° from the vertical line. The wrist was then actively moved from 10° of radial deviation to 20° of ulnar deviation in a 60-rounds-per-minute rhythm that was paced by a metronome. The articular disc displacement velocity magnitude was analyzed by using particle image velocimetry fluid measurement software. The mean area of the articular discs was larger on ulnar deviation in the control group. The mean articular disc area on radial deviation was larger in the injury group. The average articular disc velocity magnitude for the injury group was significantly higher than that for the control group. The results suggest that patients with TFCC injury lose articular disc cushioning and static stability, and subsequent abnormal motion can be analyzed by using US.Jan. 2022, Sensors (Basel, Switzerland), 22(1) (1), English, International magazineScientific journal
- Purpose: Soft tissue sarcomas (STSs) constitute a group of rare, heterogeneous tumors representing approximately 1% of all cancers. Owing to the rarity and pathological diversity of the disease, unplanned excision (UE) has often been performed for STS, resulting in an unfavorable prognosis. This study aimed to clarify clinical outcomes and prognostic factors in STS patients who underwent UE. Patients and Methods: In a retrospective review of the medical records of patients with STS who underwent surgery at our institution between 1999 and 2015, patients were enrolled to either a UE group or a planned excision (PE) group. An analysis was then conducted to identify factors associated with prognosis after UE. Results: Of 134 patients undergoing surgery for STS, 110 were enrolled to the PE group and 24 to the UE group. The median size of the primary tumor was significantly smaller, and more lesions were located in the superficial layer in the UE group than in the PE group. In addition, plastic reconstruction after additional radical resection was required significantly more often in the UE group than in the PE group. No significant difference in overall survival, local recurrence-free survival, or disease-free survival (DFS) between the UE and PE groups was observed; however, metastasis-free survival was significantly better in the UE group. In the UE group, poorer DFS was associated with older age (≥61 years) and a larger primary tumor (≥2.9 cm). Conclusion: A prognosis similar to that in patients undergoing PE could be achieved by appropriate additional surgeries in patients initially undergoing UE. However, UE for STS should be avoided, especially in older patients and those with a larger primary tumor.2022, Cancer management and research, 14, 1815 - 1824, English, International magazineScientific journal

- Osteolytic bone metastasis leads to skeletal‑related events, resulting in a decline in the patient activities and survival; therefore, it is important to understand the mechanism underlying bone metastasis. Recent studies have suggested that microRNAs (miRNAs or miRs) are involved in osteoclast differentiation and/or osteolytic bone metastasis; however, the roles of miRNAs have not been elucidated. In the present study, the roles of miRNAs in bone destruction caused by breast cancer metastasis were investigated in vitro and in vivo. miR‑16, miR‑133a and miR‑223 were transfected into a human breast cancer cell line, MDA‑MB‑231. The expression of osteolytic factors in conditioned medium (miR‑CM) collected from the culture of transfected cells was assessed. To evaluate the effects of miRNAs on osteoclast differentiation and activities, tartrate‑resistant acid phosphatase (TRAP) staining and bone resorptive assays were performed in osteoclasts following miR‑CM treatment. To create in vivo bone metastasis models for histological and morphometric evaluation, miRNA‑transfected MDA‑MB‑231 cells were transplanted into the proximal tibia of nude mice. Expression of osteolytic factors, including receptor activator for nuclear factor‑κB ligand (RANKL), interleukin (IL)‑1β, IL‑6, parathyroid hormone‑related protein (PTHrP), and tumor necrosis factor (TNF), was increased in miR‑16‑CM, whereas it was decreased in both miR‑133a‑CM and miR‑223‑CM. TRAP staining and bone resorptive assays revealed that osteoclast function and activities were promoted by miR‑16‑CM treatment, whereas they were suppressed by miR‑133a‑CM and miR‑223‑CM. Consistent with in vitro findings, in vivo experiments revealed that the overexpression of miR‑16 increased osteoclast activities and bone destruction in MDA‑MB‑231 cells, whereas the opposite results were observed in both miR‑133a‑ and miR‑223‑transfected MDA‑MB‑231 cells. Our results indicated that miR‑16 promoted osteoclast activities and bone destruction caused by breast cancer metastasis in the bone microenvironment, whereas miR‑133a and miR‑223 suppressed them. These miRNAs could be potential biomarkers and therapeutic targets for breast cancer bone metastasis.Nov. 2021, International journal of oncology, 59(5) (5), English, International magazineScientific journal
- INTRODUCTION: Excellent outcomes of arthroscopic rotator cuff repair for small and medium tears have been recently reported. However, re-tears after surgery have been a common complication after surgical repair of large and massive rotator cuff tears and often occur in early postoperative phase. It was previously reported that basic fibroblast growth factor and platelet-rich plasma enhanced rotator cuff tear healing. We hypothesized that this combined therapy could enhance rotator cuff healing after rotator cuff repair in a rat model. This study aimed to evaluate the efficacy of combined therapy of platelet-rich plasma and basic fibroblast growth factor with gelatin-hydrogel sheet. METHODS: To create a rotator cuff defect, the infraspinatus tendon of Sprague Dawley rat was resected from the greater tuberosity. The infraspinatus tendons were repaired and covered with gelatin-hydrogel sheet impregnated with PBS (control group), basic fibroblast growth factor (bFGF group), platelet-rich plasma (PRP group), or both basic fibroblast growth factor and platelet-rich plasma (combined group). Histological examinations were conducted using hematoxylin and eosin, safranin O, and immunofluorescence staining, such as Isolectin B4, type II collagen at 2 weeks postoperatively. For mechanical analysis, ultimate failure load of the tendon-humeral head complex was evaluated at 6 weeks postoperatively. RESULTS: In the hematoxylin and eosin staining, the tendon maturing score of the combined group was higher than that of the control group at postoperative 2 weeks. In the safranin O staining, stronger proteoglycan staining was observed in the combined group compared with the other groups at postoperative 2 weeks. Vascular staining with isolectin B4 in 3 treatment groups was significantly higher than that in the control group. Type II collagen expression in the combined group was significantly higher than those in the other groups. The ultimate failure load of the combined group was significantly higher than that of the control group. CONCLUSION: Combined therapy of basic fibroblast growth factor and platelet-rich plasma promoted angiogenesis, tendon maturing and fibrocartilage regeneration at the enthesis, which could enhance the mechanical strength. It was suggested that combined basic fibroblast growth factor and platelet-rich plasma might enhance both tendon and bone-tendon junction healing, and basic fibroblast growth factor and platelet-rich plasma might be synergistic.Oct. 2021, Journal of orthopaedic surgery and research, 16(1) (1), 605 - 605, English, International magazineScientific journal

- Background: Improvements in ultrasound diagnostic equipment and techniques can enable muscle stiffness to be measured quantitatively as muscle elasticity using ultrasound shear wave elastography (USWE), where high muscle elasticity values represent muscle stiffness. Purpose: To use USWE to analyze the sequential changes in muscle elasticity in the posterior shoulder before and after pitching. Study Design: Descriptive laboratory study. Methods: The authors evaluated 14 baseball players who had played in high school or college at an intermediate level. The elasticity of the supraspinatus, infraspinatus (ISP), middle trapezius, lower trapezius (LT), rhomboideus, and serratus anterior muscles of the throwing shoulder was measured using USWE at 3 time points: before, immediately after, and 24 hours after a throwing session of 100 pitches. The authors analyzed the sequential changes in the mean elasticity values of the respective muscles at the 3 time points. Results: The mean elasticity values before, immediately after, and 24 hours after throwing were as follows: supraspinatus: 32.9, 53.4, 43.8 kPa; ISP: 22.7, 44.8, 43.7 kPa; middle trapezius: 45.1, 70.3, 59.9 kPa; LT: 32.8, 45.5, 46.5 kPa; rhomboideus: 29.1, 47.5, 38.8 kPa; and serratus anterior: 19.2, 36.9, 26.5 kPa, respectively. The mean elasticity values for all tested muscles were significantly higher immediately after throwing compared with before throwing (P ≤ .0086 for all), and elasticity values in the ISP and LT remained significantly higher 24 hours after throwing compared with before throwing (P ≤ .019 for both). Conclusion: The study results indicated that pitching significantly increased ISP and LT muscle elasticity even after 24 hours.Aug. 2021, Orthopaedic journal of sports medicine, 9(8) (8), 23259671211021362 - 23259671211021362, English, International magazineScientific journal

- BACKGROUND: The accurate assessment of distal radioulnar joint (DRUJ) instability is still challenging as there is no established objective evaluation method. This study aimed to develop a noninvasive measurement method using a three-dimensional electromagnetic sensor system (EMS) to quantitatively assess and characterize the normal DRUJ movement in healthy volunteers. METHODS: The DRUJ movement was mimicked using both a block model and saw bone. Movement of the models was measured by EMS, and the accuracy and reproducibility of the measurements were assessed. In vivo measurement was performed in a sitting position with the elbow flexed and the forearm pronated. One sensor each was attached to the distal radial shaft and the ulnar head. The examiners fixed the distal radius and the carpal bones, moved the ulnar head from the dorsal to the volar side and measured the dorsovolar translation. The volar translation was measured by EMS and ultrasonography, and the correlation coefficient was calculated. The dorsovolar translation was evaluated in 14 healthy volunteers (7 men and 7 women) by three hand surgeons. The intraclass and inter-rater correlation coefficients (ICCs), the differences between the dominant and non-dominant sides and between men and women were assessed. RESULTS: The accuracy and reproducibility assessment results of the EMS showed high accuracy and reproducibility. In the comparison between EMS and ultrasonography, the correlation coefficient was 0.920 (p = 0.16 × 10-3). The ICC (1,5) for the intra-rater reliability was 0.856, and the ICC (2,5) for inter-rater reliability was 0.868. The mean ulnar head translation and difference between dominant and non-dominant sides were 6.00 ± 1.16 mm (mean ± SD) and - 0.12 ± 0.40 mm, respectively. There were no significant differences between any of the parameters. CONCLUSIONS: A new measurement method using EMS could evaluate DRUJ movement with high accuracy, reproducibility, and intra- and inter-rater reliability. In healthy volunteers, the dorsovolar ulnar head translation was 6.00 mm. The difference between the dominant and non-dominant sides was < 1.0 mm with no significant difference. EMS provided an objective, non-invasive, real-time assessment of dynamic changes in the DRUJ. These findings could be useful in the treatment of patients with DRUJ instability.Jul. 2021, Journal of orthopaedic surgery and research, 16(1) (1), 452 - 452, English, International magazineScientific journal

- BACKGROUND: Dehydroepiandrosterone (DHEA), an adrenal steroid, has a protective role against diabetes. This study aimed to investigate the in vitro and in vivo protective effects of DHEA against high glucose-induced oxidative stress in tenocytes and tendons. METHODS: Tenocytes from normal Sprague-Dawley rats were cultured in low-glucose (LG) or high-glucose (HG) medium with or without DHEA. The experimental groups were: control group (LG without DHEA), LG with DHEA, HG without DHEA, and HG with DHEA. Reactive oxygen species (ROS) production, apoptosis, and messenger RNA (mRNA) expression of NADPH oxidase (NOX) 1 and 4, and interleukin-6 (IL-6) were determined. Further, diabetic rats were divided into a control group and a DHEA-injected group (DHEA group). NOX1 and NOX4 protein expression and mRNA expression of NOX1, NOX4, IL-6, matrix metalloproteinase (MMP)-2, tissue inhibitors of matrix metalloproteinase (TIMP)-2, and type I and III collagens in the Achilles tendon were determined. RESULTS: In rat tenocytes, DHEA decreased the expression of NOX1 and IL-6, ROS accumulation, and apoptotic cells. In the diabetic rat Achilles tendon, NOX1 protein expression and mRNA expression of NOX1, IL-6, MMP-2, TIMP-2, and type III collagen were significantly lower while type I collagen expression was significantly higher in the DHEA group than in the control group. CONCLUSIONS: DHEA showed antioxidant and anti-inflammatory effects both in vitro and in vivo. Moreover, DHEA improved tendon matrix synthesis and turnover, which are affected by hyperglycemic conditions. DHEA is a potential preventive drug for diabetic tendinopathy.Jun. 2021, BMC musculoskeletal disorders, 22(1) (1), 519 - 519, English, International magazineScientific journal

- Background: Coronal shear fractures of the distal humerus are rare injuries, and fragmentation of the capitellum and trochlea with posterior comminution is challenging for surgeons. We retrospectively evaluated the functional outcomes of patients with coronal shear fractures managed with open reduction and internal fixation, focusing on the number of trochlea fragments in Dubberley type 3B fractures. Materials and methods: The functional outcomes of 25 patients, including 8 patients with type 3B fractures, with a mean age (and standard deviation) of 57 ± 20 years, were evaluated at a mean follow-up duration of 15 ± 9 months. Type 3B fractures were classified into two groups: those with two trochlea fragments or less group (group A) and those with three or more fragments (group B). Patient outcomes were assessed with clinical and radiographic examination, range of motion, and the Mayo Elbow Performance scale (MEPS). Results: Two patients with type 3B in group B experienced nonunion, and two patients with type 3B in group A and 1 patient with type 1B demonstrated avascular necrosis on radiographs. The average MEPS score was 96.3 points (range, 70-100), with 18 excellent, 5 good, and 1 fair results. The average range of motion was 10 ± 8 to 130 ± 12. The MEPS score worsened as Dubberley classification progressed from type 1 to type 3 (98.3 vs. 96.7 vs. 88, P = .014, respectively) and subtypes A to B (97.9 vs. 90, P = .014, respectively). In comparing groups A and B, the MEPS score was significantly worse in group B (93.8 vs. 76.3, P = .006). Conclusion: Our open reduction and internal fixation results were largely good, although functional outcomes were diminished as Dubberley classification progressed from type 1 to type 3 and subtype A to B. Type 3B fractures with three trochlea fragments or more in the elderly were the most difficult to treat with open reduction and internal fixation and possibly 1-term total elbow arthroplasty.May 2021, JSES international, 5(3) (3), 571 - 577, English, International magazineScientific journal

- Introduction: Musculocutaneous nerve lesion in a throwing athlete is a rare condition. We report the case of a professional baseball pitcher with an isolated musculocutaneous nerve lesion that occurred during a pitching motion. Case Presentation: The patient had radiating pain in the upper arm and weakness of elbow flexion. Physical examination revealed flaccid paralysis of the biceps brachii muscle and paresthesia in the right lateral forearm. Musculocutaneous nerve injury was suspected. Because some signs of recovery were observed within a few days, the patient received non-operative management. Nerve conduction studies at 2 weeks after the injury showed low-amplitude compound muscle action potential of the right biceps brachii muscle by stimulation of the musculocutaneous nerve. Needle electromyography showed markedly reduced motor unit potential recruitment in the biceps brachii muscle. He was diagnosed as having isolated musculocutaneous nerve injury. At 2 months after the injury, the muscle contraction and strength of the biceps brachii muscle improved. At 7 months after the injury, muscle weakness was fully recovered. His pitching ability returned to that of a competitive player. Conclusion: Because the neuroparalysis was incomplete and began to recover within a few days, we considered the pathology of this injury to be incomplete axonotmesis, which was successfully treated conservatively.Mar. 2021, Journal of orthopaedic case reports, 11(3) (3), 113 - 116, English, International magazine

- BACKGROUND/AIM: This study aimed to evaluate the association of clinical characteristics with treatment outcomes to ascertain the appropriate treatment options for soft tissue sarcomas (STS) patients with brain metastasis (BM). PATIENTS AND METHODS: Medical records of STS patients with BM who were treated in our institutions were retrospectively reviewed, and analyzed to identify the factors associated with post-BM survival. RESULTS: Among the 509 STS patients, BM occurred in five patients (0.98%). The median survival after BM was 1.5 months. Histological subtypes of the primary lesions in the five BM patients were: two synovial sarcomas, one myxoid liposarcoma, one alveolar soft part sarcoma, and one rhabdomyosarcoma. Among the five BM patients, the post-BM survival of two patients, who underwent surgery and postoperative radiotherapy, was longer than that of the other patients (p<0.01). CONCLUSION: Combined surgery and postoperative radiotherapy effectively managed symptoms and prolonged survival in STS patients with BM.Feb. 2021, Anticancer research, 41(2) (2), 1027 - 1034, English, International magazineScientific journal

- Introduction: Although the recommended treatment for humeral shaft nonunion is compression plating with autologous bone grafting, we treated a case of humeral shaft nonunion with an intramedullary nail (IMN) without bone grafting. Presentation of Case. Osteosynthesis with IMN was performed on a 24-year-old man with a humeral shaft fracture at another hospital. However, bony union was not obtained 1 year after the first surgery, and he was referred to our institution. We treated the nonunion with exchange nailing without autologous bone grafting using compression function of the nail, leading to bony union at 7 months postoperatively. At the final follow-up 2 years and 4 months postoperatively, the patient had full range of motion in the left shoulder and elbow joints. Discussion. Compression plating with autologous bone grafting is reported to be the gold standard for the treatment of humeral shaft nonunion. IMN is advantageous for minimal invasion; however, the conventional type of IMN cannot apply compression force between fragments and does not have sufficient stability against rotational force. In this case, we used an IMN that could apply compression between the fragments and which had rotational stability via many screws. We did not perform bone grafting because the current nonunion was adjudged to be biologically active, and we achieved good functional results. Conclusion: We treated humeral shaft nonunion using IMN with compression, but without bone grafting, leading to successful clinical outcomes. This strategy might be an appropriate choice for the treatment of humeral shaft nonunion with biological activity.2021, Case reports in orthopedics, 2021, 5548729 - 5548729, English, International magazine

- BACKGROUND: Previous studies have reported that glenohumeral internal rotation deficit (GIRD) may increase the risk of throwing-shoulder injuries. The purpose of this study was to analyze the conditions of the throwing shoulder in professional baseball pitchers with GIRD by comparing with those in pitchers without GIRD. METHODS: In total, 26 male professional baseball pitchers participated in this study. We evaluated passive range of motion (ROM) and isometric muscle strength at internal rotation (IR) and external rotation (ER) at 90° of abduction, as well as the muscle thickness of the supraspinatus (SSP) and infraspinatus (ISP) by ultrasound. The pitchers were divided into 2 groups: those who exhibited a loss of IR of ≥20° in the throwing shoulder (GIRD group) and those who did not (non-GIRD group). RESULTS: In the GIRD group, the total ROM deficit (throwing side - non-throwing side) (P < .001), the muscle thickness ratio (throwing to non-throwing) of the SSP and ISP (P = .017 and P = .014, respectively), and the muscle strength ratio (throwing to non-throwing) of ER (P = .028) were significantly lower than those in the non-GIRD group. In contrast, the muscle strength ratio (throwing to non-throwing) of IR was significantly higher in the GIRD group than in the non-GIRD group (P = .0064). CONCLUSIONS: We have shown that GIRD has significant correlations with several conditions, such as atrophy of the SSP and ISP, weakness of ER strength, enhancement of IR strength, limitation of total ROM, and throwing side, all of which could be important factors for throwing-shoulder injuries.Dec. 2020, Journal of shoulder and elbow surgery, 30(9) (9), 2073 - 2081, English, International magazineScientific journal
- Introduction: The majority of osteochondritis dissecans (OCD) of the elbow occurs in the humeral capitellum in adolescence while OCD in the humeral trochlea is relatively rare. We report a rare case of OCD in the humeral trochlea, which underwent mosaic-type osteochondral autologous transplantation. Case Report: A 24-year-old man, who was a gymnastic athlete, complained of severe right elbow pain for 9 years. Image findings revealed a trochlear osteochondral defect with intra-articular loose body. Due to the large defect and duration of the disease, autologous osteochondral transplantation form femoral condyle was performed. Two years after surgery, the range of elbow motion was 0° in extension and 120° in flexion. He had no pain on his elbow. Conclusion: OCD in the humeral trochlea was treated with mosaic-type osteochondral autologous transplantation form femoral condyle. Despite the large trochlear defect, osteochondral transplantation yielded a satisfactory result and this treatment might be an option for treatment of trochlear OCD.Dec. 2020, Journal of orthopaedic case reports, 10(9) (9), 106 - 108, English, International magazine

- INTRODUCTION: Diabetes mellitus (DM) negatively affects fracture repair by inhibiting endochondral ossification, chondrogenesis, callus formation, and angiogenesis. We previously reported that transcutaneous CO2 application accelerates fracture repair by promoting endochondral ossification and angiogenesis. The present study aimed to determine whether CO2 treatment would promote fracture repair in cases with type I DM. RESEARCH DESIGN AND METHODS: A closed femoral shaft fracture was induced in female rats with streptozotocin-induced type I DM. CO2 treatment was performed five times a week for the CO2 group. Sham treatment, where CO2 was replaced with air, was performed for the control group. Radiographic, histologic, genetic, and biomechanical measurements were taken at several time points. RESULTS: Radiographic assessment demonstrated that fracture repair was induced in the CO2 group. Histologically, accelerated endochondral ossification and capillary formation were observed in the CO2 group. Immunohistochemical assessment indicated that early postfracture proliferation of chondrocytes in callus was enhanced in the CO2 group. Genetic assessment results suggested that cartilage and bone formation, angiogenesis, and vasodilation were upregulated in the CO2 group. Biomechanical assessment revealed enhanced mechanical strength in the CO2 group. CONCLUSIONS: Our findings suggest that CO2 treatment accelerates fracture repair in type I DM rats. CO2 treatment could be an effective strategy for delayed fracture repair due to DM.Dec. 2020, BMJ open diabetes research & care, 8(2) (2), English, International magazineScientific journal

- The induced membrane technique has been widely used for the reconstruction of the segmental bone defect. The technique requires two-stage surgery. The first surgery is debridement of the affected bone and replacement of the defect by cement spacer. The spacer is removed at the second surgery, and the defect is filled with cancellous bone. The use of the technique for septic wrist arthritis treatment has not been reported. We report two cases of septic wrist arthritis treated by the induced membrane technique. Radical debridement including the carpal bones was performed as a first surgery. The cement spacer was placed into the bone defect after first surgery; then cancellous bone was transplanted into the induced membrane several weeks later. External fixator or plate fixation was performed simultaneously. Bone formation was observed in both cases at several months after the reconstruction surgery. There was no pain or recurrence of infection in both cases. We consider this technique is a possible method for reconstruction, especially in a difficult case.Oct. 2020, Journal of hand and microsurgery, 12(Suppl 1) (Suppl 1), S54-S57, English, International magazine

- Background: Predicting when athletes can return to play after muscle strains is not always simple because of difficulties in evaluating the severity of such injuries. Purpose/Hypothesis: The purpose of this study was to evaluate the use of magnetic resonance imaging (MRI) to classify lower extremity muscle strains in Japanese professional baseball players. The hypothesis was that MRI grading can be used to diagnose the severity of muscle strains in the lower extremity and predict return to play in athletes. Study Design: Case series; Level of evidence, 4. Methods: A total of 55 muscle strains occurred in the lower extremity of players on a professional baseball team between the 2006 and 2015 seasons; all players had undergone MRI examination. Age, player position, location of injury, cause of injury, and duration until return to play (in days) were extracted from the medical records. MRI scans were classified using the following system: grade 0, no abnormal findings; grade 1a, T2-weighted high intensity only between muscles; grade 1b, T2-weighted high intensity between muscles and in muscle belly; grade 2, injury of musculotendinous junction; and grade 3, rupture of tendon insertion. Results: The sites of injuries were distributed as follows: hamstrings (n = 33), quadriceps (n = 6), hip adductors (n = 6), and calves (n = 10). MRI findings revealed 9 muscle strains (16%), 19 grade 1a (34%), 19 grade 1b (34%), and 8 grade 2 muscle strains (16%). The length of time until return to training and competition, respectively, was 15 and 26 days for grade 1a injuries, 19 and 36 days for grade 1b injuries, and 55 and 69 days for grade 2 injuries. Conclusion: Players with grade 1 injuries took 4 to 5 weeks to return to play, whereas players with grade 2 injuries took 10 weeks to return. MRI can be useful for diagnosing lower extremity muscle strains and predicting the time to return to play.Oct. 2020, Orthopaedic journal of sports medicine, 8(10) (10), 2325967120956569 - 2325967120956569, English, International magazineScientific journal
- Bilateral Collateral Ligament Reconstruction for Chronic Elbow Dislocation.We report the case of a 37-year-old male with autism spectrum disorder who was hospitalized for chronic elbow dislocation. He had suffered a posterior elbow dislocation 5 months ago. His elbow dislocation was easily reduced, but the reduction position could not be maintained. Severe varus and valgus instabilities were observed in his right elbow. He was diagnosed with chronic elbow dislocation due to bilateral collateral ligament dysfunction and was surgically treated. Bilateral ligament reconstruction using the bilateral palmaris longus (PL) tendon combined with a temporary ulnohumeral joint fixation was performed. Cast immobilization was applied for 6 weeks. One year after surgery, his range of motion was -15° in extension, 140° in flexion, 80° in pronation, and 90° in supination. He did not face any problems in daily activities.Sep. 2020, The Kobe journal of medical sciences, 66(2) (2), E71-E74, English, Domestic magazineScientific journal

- Locking of the thumb metacarpophalangeal joint is a relatively rare condition. We report successful treatment in 11 cases of locking of the thumb. Ten patients were diagnosed at an average of 3.2 days (range: 0-21 days) from the injury onset, whereas one patient was diagnosed at 4 months from the injury. Seven of 11 cases underwent successful manual reduction, whereas the other four cases required surgical treatment. Among the surgically treated cases, all cases had a sharp prominent of the radial condyle of the metacarpal head. Therefore, this case series showed 1 chronic case and 4 of 10 cases with a nonround shape of metacarpal heads requiring open reduction.Apr. 2020, Journal of hand and microsurgery, 12(1) (1), 62 - 66, English, International magazineScientific journal

- Isolated Nerve Grafting for a Young Patient with a Complete Common Peroneal Nerve Palsy Following a Traumatic Knee Dislocation: A case report.BACKGROUND: Common peroneal nerve (CPN) injury following a knee dislocation is a serious problem, and an optimal treatment is yet to be established. We report a case of complete CPN palsy following a knee dislocation treated with sural nerve grafting. CASE: A 19-year-old man suffered a knee injury during a hurdle race. Diagnosis in a previous hospital revealed a complex ligament injury with CPN palsy. Ten weeks following injury, he was admitted to our institution because of a lack of neurological improvement. Considering the grade 0 results obtained in the manual muscle test (MMT) of tibialis anterior (TA) and extensor hallucis longus (EHL), the patient was diagnosed with complete neurotmesis of CPN, and surgery was performed. Operative findings revealed CPN discontinuity and an extended nerve defect length of 15 cm; therefore, sural nerve grafting was performed to repair the CPN injury. One year postoperatively, a grade 1 result from MMT of TA and EHL indicated a gradual neurological recovery. Three years postoperatively, MMT of TA and EHL showed significant improvement to grade 4+ and grade 4, respectively, and he could walk and jog without a knee brace. DISCUSSION: Nerve graft length of >6 cm has shown limited success, and their efficacy for the treatment of CPN palsy following knee dislocations is controversial. However, young patients with complete CPN lesion are more likely to recover regardless of the length of nerve injury. Therefore, in such cases, nerve grafting can be considered as one of the treatments for complete CPN lesion following knee dislocations.Jan. 2020, The Kobe journal of medical sciences, 65(3) (3), E110-E113, English, Domestic magazineScientific journal

- BACKGROUND: Rad is the prototypic member of a subfamily of Ras-related small G-proteins and is highly expressed in the skeletal muscle of patients with type II diabetes. Our previous microarray analysis suggested that Rad may mediate fracture nonunion development. Thus, the present study used rat experimental models to investigate and compare the gene and protein expression patterns of both Rad and Rem1, another RGK subfamily member, in nonunions and standard healing fractures. METHODS: Standard healing fractures and nonunions (produced via periosteal cauterization at the fracture site) were created in the femurs of 3-month-old male Sprague-Dawley rats. At post-fracture days 7, 14, 21, and 28, the fracture callus and fibrous tissue from the standard healing fractures and nonunions, respectively, were harvested and screened (via real-time PCR) for Rad and Rem1 expression. The immunolocalization of both encoded proteins was analyzed at post-fracture days 14 and 21. At the same time points, hematoxylin and eosin staining was performed to identify the detailed tissue structures. RESULTS: Results of real-time PCR analysis showed that Rad expression increased significantly in the nonunions, compared to that in the standard healing fractures, at post-fracture days 14, 21, and 28. Conversely, immunohistochemical analysis revealed the immunolocalization of Rad to be similar to that of Rem1 in both fracture types at post-fracture days 14 and 21. CONCLUSIONS: Rad may mediate nonunion development, and thus, may be a promising therapeutic target to treat these injuries.Dec. 2019, BMC musculoskeletal disorders, 20(1) (1), 602 - 602, English, International magazine[Refereed]Scientific journal

- Introduction: We treated two cases of humeral shaft nonunion by minimally invasive plate osteosynthesis (MIPO) without autogenous bone grafting. Presntation of case: Case 1: An osteosynthesis with intramedullary nailing (IMN) was performed on a 17-year-old female for a humeral shaft fracture at another hospital; however, bony union was not obtained. We removed the nail and screws, then performed MIPO without autogenous bone grafting. At the final follow-up of 4 years after the surgery, she had obtained full range of motion.Case 2: Osteosynthesis with Rush pins had been performed in a 73-year-old female for a humeral shaft fracture at another hospital. Five months later, a revision surgery using IMN was performed at the same hospital; however, this led to nonunion. We removed the IMN and performed MIPO without autogenous bone grafting. At the final follow-up 2 years after surgery, she had obtained full range of motion. Discussion: The cause of nonunion is the lack of mechanical instability and/or biological activity. In these cases, from the findings of radiography and bone scintigraphy, mechanical instability was thought to be the primary cause; therefore, in order to enhance stability, we used a locking plate. Because we can see that these cases are biologically active, we decided not to use bone grafting. Both our cases successfully achieved bony union and excellent functional recovery using this method. Conclusion: We performed MIPO without exposure of the nonunion site and autogenous bone grafting in two cases of humeral shaft nonunion, and obtained successful clinical outcomes.Dec. 2019, Annals of medicine and surgery (2012), 48, 43 - 47, English, International magazine[Refereed]

- BACKGROUND: Carbon dioxide therapy has been reported to be effective in treating certain cardiac diseases and skin problems. Although a previous study suggested that transcutaneous carbon dioxide application accelerated fracture repair in association with promotion of angiogenesis, blood flow, and endochondral ossification, the influence of the duration of carbon dioxide application on fracture repair is unknown. The aim of this study was to investigate the effect of the duration of transcutaneous carbon dioxide application on rat fracture repair. METHODS: A closed femoral shaft fracture was created in each rat. Animals were randomly divided into four groups: the control group; 1w-CO2 group, postoperative carbon dioxide treatment for 1 week; 2w-CO2 group, postoperative carbon dioxide treatment for 2 weeks; 3w-CO2 group, postoperative carbon dioxide treatment for 3 weeks. Transcutaneous carbon dioxide application was performed five times a week in the carbon dioxide groups. Sham treatment, where the carbon dioxide was replaced with air, was performed for the control group. Radiographic, histological, and biomechanical assessments were performed at 3 weeks after fracture. RESULTS: The fracture union rate was significantly higher in the 3w-CO2 group than in the control group (p < 0.05). Histological assessment revealed promotion of endochondral ossification in the 3w-CO2 group than in the control group. In the biomechanical assessment, all evaluation items related to bone strength were significantly higher in the 3w-CO2 group than in the control group (p < 0.05). CONCLUSIONS: The present study, conducted using an animal model, demonstrated that continuous carbon dioxide application throughout the process of fracture repair was effective in enhancing fracture healing.Oct. 2019, Journal of orthopaedic science : official journal of the Japanese Orthopaedic Association, 25(5) (5), 886 - 891, English, Domestic magazine[Refereed]Scientific journal

- BACKGROUND: Limitations of shoulder range of motion (ROM) have been reported to be at high risk for shoulder disorders in baseball players. In this study, we assessed posterior shoulder muscle stiffness using shear wave elastography in baseball players with and without posterior shoulder tightness. MATERIALS AND METHODS: In total, 21 college baseball players volunteered to participate in this study. Passive ROMs for shoulder abduction and horizontal adduction were measured using a goniometer. Subsequently, we divided all participants into 2 groups based on the differences between bilateral shoulder ROMs: STIFF+ and STIFF- groups. Thickness and elasticity of the posterior and inferior shoulder muscles were assessed using ultrasound. RESULTS: Shoulder abduction ROM on the throwing side was 114.5° ± 5.3° and 131.3° ± 5.7° in the STIFF+ and STIFF- groups, respectively, which was significantly different between the 2 groups (P = .023). Horizontal adduction ROM on the throwing side was 96.6° ± 4.9° and 110.9° ± 4.8° in the STIFF+ and STIFF- groups, respectively, which was also significantly different between the 2 groups (P = .014). The elasticity of infraspinatus and lower trapezius in the STIFF+ group was significantly greater than that in the STIFF- group (P = .018 and .033, respectively). DISCUSSION: In this study, we found that the elasticity of infraspinatus and lower trapezius in stiff shoulders was significantly greater than that in nonstiff shoulders, which indicated that the infraspinatus and lower trapezius could be the key muscles in posterior shoulder tightness.Sep. 2019, Journal of shoulder and elbow surgery, 29(3) (3), 571 - 577, English, International magazine[Refereed]Scientific journal
- BACKGROUND: Most rotator cuff tears are the result of age-related degenerative changes, but the mechanisms underlying these changes have not been reported. Recently, advanced glycation end products (AGEs) have been regarded as an important factor in senescence. Therefore, we hypothesized that AGEs would have detrimental effects on rotator cuff-derived cells. In this study, we investigated the influence of AGEs on rotator cuff-derived cells in vitro and ex vivo. METHODS: Rotator cuff-derived cells were obtained from human supraspinatus tendons. The cells were cultured in the following media: (1) regular medium with 500 μg/mL AGEs (High-AGEs), (2) regular medium with 100 μg/mL AGEs (Low-AGEs), and (3) regular medium alone (Control). Cell viability, secretion of vascular endothelial growth factor, and the expressions of hypoxia-inducible factor-1α, reactive oxygen species, and apoptosis were assessed after cultivation. An ex vivo tissue culture with AGEs was also performed to measure the tensile strength. RESULTS: Cell viability in the High-AGEs group was significantly suppressed relative to that in the Controls. The amount of vascular endothelial growth factor secretion was significantly greater in the High- and Low-AGEs groups than in the Controls. Immunofluorescence stain demonstrated enhancement of hypoxia-inducible factor-1α and reactive oxygen species expressions and cell apoptosis in the High- and Low-AGEs groups relative to that in the Controls. In ex vivo mechanical testing, tensile strength was significantly higher in the Control group than in the AGEs groups. DISCUSSION: These results indicated that AGEs caused age-related degenerative rotator cuff changes. The reduction of AGEs might prevent rotator cuff senescence-related degeneration.Aug. 2019, Journal of shoulder and elbow surgery, 28(8) (8), 1490 - 1496, English, International magazine[Refereed]Scientific journal
- Introduction: Medial clavicle fractures are rare injuries. Symptomatic nonunion arises up to 8% of medial clavicle fractures when treated conservatively. Presentation of case: A 53-year-old man sustained a left medial clavicle fracture and was treated conservatively at another hospital. Nine months after his initial injury, he was referred to our institution. We diagnosed pseudarthrosis of the medial clavicle. We performed open reduction and internal fixation using an inverted distal clavicle locking plate. At the 1-year follow-up, radiographs showed bone union. Discussion: This is the first reported case of medial clavicle pseudarthrosis treated with an inverted distal clavicle anatomical locking plate. There are several advantages in using this plate. Conclusion: This method is a good treatment option.Aug. 2019, Annals of medicine and surgery (2012), 44, 1 - 4, English, International magazine[Refereed]

- BACKGROUND: Aging impairs tendon healing and is a potential risk factor for chronic tendinitis. During normal aging, tendons undergo structural and biomechanical degenerative changes, accompanied by a reduction in the number of tenocytes and changes to their properties. However, molecular changes in aged tendons under inflammatory conditions are not well understood. The present study analyzed the molecular changes in collagenase induced acute tendon injury using a senescence-accelerated mouse (SAM) model. METHODS: SAMP6 mice were used as an aging animal model and SAMR1 mice were used as a control to represent a senescence-resistant inbred strain. All the mice used in the study were 40 weeks old. Collagenase I from Clostridium histolyticum (20 μL) was injected percutaneously to the tendon-bone junction of the Achilles tendon. Two weeks after treatment, the Achilles tendons were harvested and stained using Picrosirius Red to determine collagen expression. Real-time PCR was performed to analyze gene expression of IL-6, tenomodulin, type I and type II collagen, MMP-9, TIMP-1, and TIMP-2. RESULTS: Collagenase injection resulted in significantly higher gene expression of IL-6 but significantly lower tenomodulin expression compared with the control in SAMP6 and SAMR1 mice. In SAMP6 mice, gene expression of type III collagen and MMP-9 was significantly higher in the collagenase-injected group compared with the control group. SAMP6 mice also showed lower expression of type I collagen, TIMP-1, and TIMP-2 in the collagenase-injected group compared with the control group. Picrosirius Red staining showed the highest expression of type III collagen in the collagenase-injected SAMP6 group compared with the other groups. CONCLUSIONS: The collagenase-injected SAMP6 group showed higher expression of IL-6, MMP-9, and type III collagen and lower expression of type I collagen, TIMP-1, and TIMP-2, which are known to suppress metalloproteinases. The results indicate that aging may lead to dysfunction of the tendon healing process after acute tendon injury.Mar. 2019, BMC musculoskeletal disorders, 20(1) (1), 120 - 120, English, International magazine[Refereed]Scientific journal

- Olecranon apophyseal nonunion is an elbow injury from overuse that affects adolescent athletes such as baseball pitchers who participate in overhead throwing sports. However, such injury is rare in collision sports. Here, we report two patients with this condition who are Judo athletes. The purpose of this report was to describe three elbows with olecranon apophyseal nonunion in two adolescent patients participating in Judo. This is a case series; the level of evidence is 4. Two 15-year-old patients were evaluated. One suffered from unilateral and the other from bilateral chronic posterior elbow pain. They were diagnosed with olecranon apophyseal nonunion, which was treated using internal fixation and bone grafting. Radiographic evidence of the apophyseal union was observed four months postsurgery. Two elbows were treated with tension band wiring, then they underwent hardware removal six months postsurgery. Both patients returned to their previous levels of activities six months postsurgery. Internal fixation using autologous bone grafting was a useful treatment for these Judo athletes with olecranon apophyseal nonunion.Dec. 2018, Case Rep Orthop, 2018, 8256074 - 8256074, English, International magazine[Refereed]Scientific journal

- Dorsal extension block pinning is a commonly performed surgical technique for acute bony mallet fingers. However, the treatment of chronic bony mallet finger remains controversial. We investigated the use of dorsal extension block pinning with percutaneous curettage for chronic bony mallet fingers. Seven patients with chronic bony mallet fingers were treated by dorsal extension block pinning with percutaneous curettage. The average age was 17 (range, 12-23) years, and the average time from injury to surgery was 20 (range, 7-49) weeks. Bone union was achieved in all patients. None of the patients experienced pain after bone union. The average loss of distal interphalangeal joint extension was 6 (range, 5-20) degrees, and the average flexion was 59 (range, 40-80) degrees. The Crawford functional score was excellent in three patients, good in two, and fair in two. Dorsal extension block pinning with percutaneous curettage could be a useful treatment for chronic bony mallet fingers.Nov. 2018, Case Rep Orthop, 2018, 7297951 - 7297951, English, International magazine[Refereed]Scientific journal
- Case Series of Comminuted Olecranon Fracture Treated by Plate Fixation; Do We Have to Remove the PlateComminuted olecranon fracture requires surgical intervention. Plate fixation has been performed on the majority of cases. We reviewed the cases of comminuted olecranon fracture in young and middle age treated by plate osteosynthesis and analyzed the functional outcome, complications and ratio and timing of hardware removal. Fifteen cases of comminuted olecranon fractures treated by plate fixation were reviewed. Bone union was achieved in all cases, the average range of motion at the final follow up was -11° in extension, 133° in flexion, 89° in pronation and 88° in supination. Hardware removal performed in 12 cases in average 8.3 months postoperatively, in 2 cases elbow joint contracture release was performed during the hardware removal. In the co-payment (+) group, 4 cases (67%) removed the plate at average six months postoperatively. On the other hand, no co-payment group (workman's compensation insurance or automobile liability insurance) underwent hardware removal surgery in 8 cases (89%) at 9.6 months postoperatively. There was no statistical difference between the timing or prevalence of hardware removal between the groups. The present study showed high removal rate of hardware despite the excellent clinical result. The surgeons should be aware that plate fixation of the olecranon fracture requires the removal of a plate in the majority of cases.Nov. 2018, Kobe J Med Sci, 64(3) (3), E115 - E118, English, Domestic magazine[Refereed]Research institution

- BACKGROUND: Fascia lata augmentation of massive rotator cuff tears has shown good clinical results. However, its biological effect during the early healing process is not clearly understood. The purpose of the study was to evaluate the biological efficacy of fascia lata augmentation during the early healing process of rotator cuff tears using a rabbit rotator cuff defect model. METHODS: The infraspinatus tendon was resected from the greater tuberosity of a rabbit to create a rotator cuff tear. The tendon edge was directly sutured to the humeral head. The rotator cuff repaired site was augmented with a fascia lata autograft (augmentation group, group A). The rotator cuff defect in the contralateral shoulder was repaired without augmentation (reattachment group, group R). A group with intact rotator cuff was set as the control group. Histological examinations and mechanical analysis were conducted 4 and 8 weeks postoperatively. RESULTS: In the HE staining, the tendon maturing score of group A was higher than that of group R at 4 weeks postoperatively. In the safranin O staining, proteoglycan staining at the repaired enthesis in group A at 4 weeks postoperatively was stronger than that in group R. Picrosirius red staining showed that type III and type I collagen in group A was more strongly expressed than that in group R at 4 weeks postoperatively. The ultimate failure load of the infraspinatus tendon-humeral head complex in group A was statistically higher than that in group R at 4 weeks postoperatively. The ultimate failure load of group A was similar to that of the control group. CONCLUSION: The biological and mechanical contribution of fascia lata augmentation for massive rotator cuff tears was analyzed in this study. Type III collagen was reported to be expressed during the tendon healing process. Although the biological action similar to natural ligament healing occurred around the fascia lata grafts, type III collagen was gradually replaced by type I collagen as the tissue matured. Our results suggest that fascia lata augmentation could stimulate biological healing and provide initial fixation strength of the repaired rotator cuff.Aug. 2018, J Orthop Surg Res, 13(1) (1), 200 - 200, English, International magazine[Refereed]Scientific journal

- The acceleration of nerve regeneration remains a clinical challenge. We previously demonstrated that transcutaneous CO2 application using a novel hydrogel increases the oxygen concentration in local tissue via an "artificial Bohr effect" with the potential to prevent muscle atrophy. In this study, we investigated the effect of transcutaneous CO2 administration on limb function after peripheral nerve injury in a rat sciatic nerve injury model. In total, 73 Sprague-Dawley rats were divided into a sham group, a control group (crush injury to sciatic nerve and no treatment) or a CO2 group (crush injury with transcutaneous CO2 application). CO2 was administered percutaneously for 20 min five times per week. Scores for the sciatic function index and pinprick test were significantly higher in the CO2 group than control group. The muscle wet weight ratios of the tibialis anterior and soleus muscles were higher in the CO2 group than control group. Electrophysiological examination showed that the CO2 group had higher compound motor action potential amplitudes and shorter distal motor latency than the control group. Histological examination of the soleus muscle sections at postoperative week 2 showed shorter fiber diameter in the control group than in the CO2 group. The mRNA expression of Atrogin-1 and MuRF-1 was lower, mRNA expression of VEGF and myogenin and MyoD was higher in CO2 group at postoperative week 2 compared to the control group. CLINICAL SIGNIFICANCE: Transcutaneous CO2 application has the therapeutic potential to accelerate the recovery of muscle atrophy in peripheral nerve injury. © 2017 Orthopaedic Research Society.

- 糖負荷がラットアキレス腱細胞に及ぼす影響について検討した。正常ラットアキレス腱細胞を高グルコース培地で培養した群(高グルコース群)と通常グルコース培地で培養した群(対照群)に分け、比較した。その結果、高グルコース群では腱細胞におけるNOX1、NOX4の発現量が増加し、酸化ストレスとなるROSの産生の増加を認めた。更に腱の主要構成成分である1型コラーゲンの発現が減少し、細胞増殖活性の低下がみられた。以上より、糖尿病における腱障害の一因として高血糖によって生じた酸化ストレスが関与している可能性が示唆された。(一社)日本肩関節学会, Mar. 2017, 肩関節, 40(3号) (3号), 1005 - 1008, Japanese[Refereed]Scientific journal

- Excellent clinical results of arthroscopic repair of rotator cuff tears have been reported. However, retears after surgical repair of large and massive rotator cuff tears are one of the most common complications. We present single-row repair with graft augmentation of the fascia lata for large and massive rotator cuff tears to reduce tension at the tendon-bone repair site, and this technique may prevent retears of the repaired rotator cuff. A candidate for this technique is a patient who has a large or massive rotator cuff tear in which the torn edge cannot reach the footprint after mobilization of the torn rotator cuff. This technique could provide an excellent option for irreparable large and massive rotator cuff tears.Oct. 2016, Arthrosc Tech, 5(6) (6), e1235 - e1238, English, International magazine[Refereed]Scientific journal

- 化膿性肩関節炎の鏡視下術後に両下肢麻痺をきたし治療に難渋した1例63歳男。肝硬変で、約2週間続く右肩痛と40℃の発熱、局所の発赤・腫脹を主訴とした。血液検査でCRP値と白血球数の上昇を認め、関節穿刺液で白血球増多とグラム陽性球菌を認めた。化膿性肩関節炎と診断し、関節鏡視下に病巣掻爬を行った。術中、関節内の軽度の滑膜増生と広範囲の腱板断裂を認め、関節内の滑膜組織を切除・洗浄し、Penroseドレーンを留置した。術後3日に両下肢麻痺が出現し、MRIでTh10/11レベルの胸椎化膿性脊椎炎を認めた。病巣掻爬と胸椎固定術を行い、術中組織から右肩関節と同じくグラム陽性球菌が検出された。術後、右肩と麻痺症状は徐々に改善し、右肩は初回手術のみで感染の鎮静化が得られた。しかし、背部創は治癒せずに離開し、創部からMRSAが検出された。術後1.5ヵ月に抜釘術を行い、ようやく創治癒を得た。術後2年の現在、右肩関節の可動域制限が残存するが、感染の再燃は認めていない。(一社)日本関節鏡・膝・スポーツ整形外科学会, Mar. 2016, JOSKAS, 41(1) (1), 58 - 59, Japanese
- 症例は74歳男性で、交通事故により右鎖骨骨幹部骨折を受傷した。受傷後2週にチタン製プレートを用いた観血的骨接合術が施行されたが、骨癒合は得られなかった。著者等の病院を紹介受診し、初診時の身体所見で右鎖骨部から前胸部にかけて広範囲に発赤を認めた。単純X線で鎖骨のプレートの明らかな破損は認められなかった。感染徴候に乏しかったため、金属アレルギーの可能性を考慮し金属パッチテストを行った。その結果、Coが陽性、Ti、Mn、Znが弱陽性であった。皮膚症状は金属アレルギーによるものと考え、ステロイド外用剤による治療を行った。受傷後9ヵ月の時点で偽関節となったため、生体吸収素材と自家骨移植を用いた観血的骨接合術を施行した。術後3ヵ月のCT画像で骨癒合が確認された。生体吸収素材は金属アレルギーにより金属製インプラントが使えない場合に有用な骨接合材の一つになり得ると考えられた。(一社)中部日本整形外科災害外科学会, Mar. 2016, 中部日本整形外科災害外科学会雑誌, 59(2号) (2号), 403 - 404, Japanese[Refereed]Scientific journal

- Two Extension Block Kirschner Wires' Technique for Bony Mallet ThumbMallet fingers with an avulsion fracture of the distal phalanx or rupture of the terminal tendon of the extensor mechanism is known as a common injury, while mallet thumb is very rare. In this paper, the case of a 19-year-old woman with a sprained left thumb sustained while playing basketball is presented. Plain radiographs and computed tomography revealed an avulsion fracture involving more than half of the articular surface at the base of the distal phalanx. Closed reduction and percutaneous fixation were performed using the two extension block Kirschner wires' technique under digital block anesthesia. At 4 months postoperatively, the patient had achieved excellent results according to Crawford's evaluation criteria and had no difficulties in working or playing basketball. Various conservative and operative treatment strategies have been reported for management of mallet thumb. We chose the two extension block Kirschner wires' technique to minimize invasion of the extensor mechanism and nail bed and to stabilize the large fracture fragment.2016, Case Rep Orthop, 2016, 8086594 - 8086594, English, International magazine[Refereed]Scientific journal

- PURPOSE: The PainVision™ system was recently developed for quantitative pain assessment. Here, we used this system to evaluate the effect of plexus brachialis block on postoperative pain after arthroscopic rotator cuff repair. METHODS: Fifty-five patients who underwent arthroscopic rotator cuff repair were included in this study. First 26 cases received no plexus brachialis block (control group), and the next 29 cases received the plexus brachialis block before surgery (block group). Patients completed the visual analog scale at 4, 8, 16, and 24 hours after surgery, and the intensity of postoperative pain was assessed with PainVision™ at 16 hours. The postoperative use of non-steroidal anti-inflammatory agents was also recorded. RESULTS: The pain intensity at 16 hours after surgery assessed by PainVision™ was significantly lower in the block group than in the control group (block, 252.0 ± 47.8, control, 489.0 ± 89.1, P < 0.05). However, there were no differences in the VAS values at 16 hours between the 2 groups (block, 4.3 ± 0.6, control, 5.7 ± 0.4, P = N.S.). The pain intensity and VAS at 16 hours after surgery were highly correlated (r = 0.59, P = 0.006 in the block group and r = 0.62, P = 0.003 in the control group). The effect size of the assessment by PainVision™ was bigger than that of VAS (r=0.31 in VAS and 0.51 in Pain vision). CONCLUSION: The PainVision™ system could be useful to evaluate postoperative pain because it enables the quantification and comparison of pain intensity independent of individual pain thresholds.May 2015, Open Orthop J, 9, 89 - 93, English, International magazine[Refereed]Scientific journal

- 著者らは超音波検査を用いた短母指外転筋(APB)および母指対立筋(OPP)の評価方法を考案し、健常ボランティア68例を対象に検討した。その結果、今回対象とした20〜30歳代の健常人では、OPP、APBの測定値において標準偏差のばらつきの少ない測定結果が得られた。OPP、APBは男女とも20〜30歳代間での差がなく、右側で大きい傾向を示したが、左側との有意差はなかった。男女間での比較では、男性の20歳代APB(右、左)および30歳代APB(右)において同年代の女性よりも有意に高値であったことから、測定値を個体間で比較する際には男女を分けて検討する必要があると思われた。(株)南江堂, Mar. 2015, 整形外科, 66(3) (3), 241 - 243, Japanese

- We present a case of carpal tunnel syndrome caused by systemic tumoral calcinosis. A 54-year-old woman experienced hand numbness that persisted for nine months. She had no family history or medical problem. A plain radiograph of her right wrist showed a calcified mass on the volar side of the wrist joint. The patient also experienced pain in her contralateral wrist joint and both right and left shoulders, which had calcification on radiography around the joint. Her condition was diagnosed as carpal tunnel syndrome caused by systemic tumoral calcinosis and a resection biopsy was performed. Histopathological analysis of the biopsied specimen showed basophile deposition inside the fibrous connective tissue. At 14 months after the treatment, she no longer had pain or numbness in her fingers and there was no recurrence of the mass. This patient's condition is considered as a case of nonfamilial, systemic primary tumoral calcinosis. Since incomplete resection leads to a recurrence of the lesion, a follow-up radiography examination is needed to monitor symptom recurrence.2015, Case Rep Orthop, 2015, 170873 - 170873, English, International magazine[Refereed]Scientific journal

- 著者等は、腱板修復術の成績を向上させるためには腱付着部の再生が重要と考え、ヒト腱板断裂組織由来細胞の多分化能について研究を行ってきた。今回、低出力超音波パルス(LIPUS)照射によって腱骨移行部の修復を促進すれば早期に力学的な強度が回復するのではないかと考え、ヒト腱板断裂組織由来細胞の腱分化能への影響について検討した。方法は、鏡視下腱板修復術施行例4例から分離したヒト腱板断裂組織由来細胞を平面培養し、LIPUS照射群とコントロール群に分け、腱分化の指標として[Type I collagen(collagen I)][Type III collage(collagen III)][Scleraxis(SCX)]の発現をreal-time PCR法で解析した。結果、培養5日目にはコントロール群に比べてLIPUS照射群で3指標とも有意な発現増強を認めたが、培養10日目にはcollage Iとcollage IIIの発現に有意な群間差なく、SCXの発現はLIPUS群が有意に低かった。(一社)日本肩関節学会, Oct. 2014, 肩関節, 38(2) (2), 591 - 594, Japanese

- DNA damage is a cause of age related pathologies, including osteoarthritis (OA). Excision repair cross complementation group 1 (ERCC1) is an endonuclease required for DNA damage repair. In this study we investigated the function of ERCC1 in chondrocytes and its association with the pathophysiology of OA. ERCC1 expression in normal and osteoarthritic cartilage was assessed, as were changes in ERCC1 expression in chondrocytes under catabolic stress. Inhibiting ERCC1 in chondrocytes under interleukin-1β stimulation using small interfering RNA (siRNA) was also evaluated. Finally, cellular senescence and apoptosis were examined in relation to ERCC1 function. ERCC1 expression was decreased in OA cartilage and increased within 4 h of exposure to interleukin (IL)-1β, but decreased after 12 h. The inhibition of ERCC1 by siRNA increased the expression of matrix metallopeptidase 13 and decreased collagen type II. ERCC1 inhibition also increased the number of apoptotic and senescent cells. The inhibition of ERCC1 in chondrocytes increased their expression of OA related proteins, apoptosis, cellular senescence, and hypertrophic-like changes which suggest that ERCC1 is critical for protecting human chondrocytes (HCs) from catabolic stresses and provides insights into the pathophysiology of OA and a potential target for its treatment.

- We present a case of concurrent rotator cuff tear and axillary nerve palsy resulting from anterior dislocation of the shoulder and a large glenoid rim fracture-a "terrible tetrad." A 61-year-old woman fell on her right shoulder. Radiographs showed anterior dislocation of the shoulder with a glenoid rim fracture, and an MRI two months after injury revealed a rotator cuff tear. Upon referral to our hospital, physical and electrophysiological examinations revealed axillary nerve palsy. The axillary nerve palsy was incomplete and recovering, and displacement of the glenoid rim fracture was minimal and already united; therefore, we surgically repaired only the rotator cuff tear three months after injury. The patient recovered satisfactorily following the operation. In patients whose axillary nerve palsy is recovering, surgeons should consider operating on rotator cuff tears in an attempt to prevent rotator cuff degeneration.2014, Case Rep Orthop, 2014, 312968 - 312968, English, International magazine[Refereed]Scientific journal

- BACKGROUND: As a result of recent studies describing the double-bundle anterior cruciate ligament (ACL), selected ACL augmentation procedures, either anteromedial (AM) or posterolateral (PL), have been introduced as the treatment of choice for partial ACL ruptures. The preserved mechanoreceptor and vascularity of the remnant ACL are considered to provide additional biological benefits. Although enhanced knee joint proprioception in ACL augmented patients has been previously reported, there is no study assessing biological healing advantages of the graft after the ACL augmentation procedure. HYPOTHESIS: Selected ACL augmentation for partial tears can accelerate the healing process of the grafted tendon, which promotes better biomechanical recovery of the tendon, compared with conventional ACL reconstruction of complete tears. STUDY DESIGN: Controlled laboratory study. METHODS: Two rat models were established in this study: an ACL augmentation partial tear model and conventional ACL reconstruction for a complete tear. Biological assessments of cellularity and angiogenesis were measured by hematoxylin and eosin staining and immunostaining, respectively. Additionally, rat-specific type III collagen and α-smooth muscle actin were evaluated by immunohistochemical staining to analyze the healing process, whereas anti-rat neurofilament antigen was assessed to examine proprioceptive recovery. Biological assessments of the augmented and reconstructed grafts were conducted postoperatively at week 2, whereas biomechanical testing was performed postoperatively at week 8. RESULTS: An increase in cellularity and angiogenesis was observed in the augmented grafts compared with the conventionally reconstructed grafts. Also, increased amounts of rat-specific type III collagen, α-smooth muscle actin, and anti-rat neurofilament antigen were expressed in the augmented grafts. Biomechanical testing showed that failure to load was significantly higher in the augmentation group compared with the conventional reconstruction group (augmentation, 15.9 ± 1.0; reconstruction, 7.0 ± 1.3; P < .01). CLINICAL RELEVANCE: Selected ACL augmentation could be a good choice for the repair of partial ACL injury by preserving the uninjured portion of the ACL, which in turn could maintain the anatomic position of the ligament and its biomechanical function.Feb. 2013, The American journal of sports medicine, 41(2) (2), 365 - 73, English, International magazine[Refereed]Scientific journal
- Background: Low-intensity pulsed ultrasound (LIPUS) has been used for fracture healing and its effectiveness has been confirmed. To prevent re-tear of the repaired rotator cuff, it is important to regenerate the tendon-to-bone interface after rotator cuff repair. Therefore, we have investigated the effect of LIPUS on human rotator cuff derived cells hypothesizing that their osteogenic activity would increase by LIPUS exposure.Japan Shoulder Society, 2013, Katakansetsu, 37(2) (2), 721 - 724, Japanese
Methods: Human rotator cuff derived cells were adapted to a six well plate. The medium was replaced with the osteogenic medium, and the cells were divided into the two groups. In the LIPUS group, LIPUS was applied for 20 minutes every day for 10 days. Cells without LIPUS exposure acted as a control group. Then they were analyzed by cell number count, Alizarin Red staining and real time PCR analyses.
Results: There was no significant difference in the total number of cells between the two groups at 10 days. Alizarin Red staining of LIPUS-treated cells was better stained than that of the control group after 10 days. In the LIPUS group, the expressions of ALP and Runx2 were significantly higher than those in the control group.
Discussion: This study showed that the osteogenic activity of human rotator cuff derived cells was increased by LIPUS exposure. These results could show a way for rotator cuff repair in early healing of the tendon-to-bone interface by LIPUS exposure. - 2013, CELL TRANSPLANTATION, 22(7) (7), 1201 - 1211, English[Refereed]Scientific journal

- Background: As arthroscopic shoulder surgery is often associated with severe postoperative pain, it is reported to be important to manage it. We evaluated the effect of the plexus brachialis block to reduce post operative pain after arthroscopic rotator cuff repair.Japan Shoulder Society, Aug. 2012, 肩関節, 36(2号) (2号), 559 - 561, Japanese
Methods: Thirty-five patients with arthroscopic rotator cuff repair were divided into 2 groups; 1) Block group (with plexus brachialis block) which included 9 men and 6 women, with a mean age of 66.5 years old, 2) Control group (without plexus brachialis block) which included 14 men and 6 women, with a mean age of 64.0 years old. Under general anesthesia, the plexus brachialis blocking was performed using the ultrasonographic guide. Post operative pain was assessed using visual analog scale (VAS) and the usage of the NSAIDs at 4, 8, 16 and 24 hours after surgery.
Results: The VAS at 4 and 8 hours postoperatively were significantly lower in the Block group than the Control group. The VAS at 16 and 24 hours were also lower in the Block group when compared with the Control group. The total amount of the painkillers used during the first postoperative 24 hours was greater in the Control group compared with the Block group. As for complications, fugitive motor paralysis, which recovered within several hours, was found in some patients, but no severe complications such as nerve injury or pneumothorax were seen.
Conclusion: The plexus brachialis blockade is effective to reduce post operative pain after arthroscopic rotator cuff repair.[Refereed]Scientific journal - Background: Good clinical outcomes of arthroscopic rotator cuff repair (ARCR) have been reported. Recently, the suture bridge technique, which is a surface holding method, was developed. The purpose of this study is to evaluate the cuff integrity of ARCR using suture bridge technique depending on tear size.Japan Shoulder Society, Aug. 2012, 肩関節, 36(2号) (2号), 585 - 587, Japanese
Methods: Thirty six patients (24 male, 12 female, average age 63.7 years old) who under went ARCR with the suture bridge technique were evaluated at 6 months postoperatively. The patients were classified into two groups which were small tear group (group S, <3cm, 21 shoulders) and large tear group (group L, 3cm<, 15 shoulders). The JOA score of the two groups was assessed, and the cuff integrity was evaluated by MRI.
Results: JOA score increased significantly in both group S and group L. The mean JOA score increased from 70.4 to 89.4 in group S and from 68.3 to 89.9 in group L, at 6 months postoperatively. There was no significant difference between the two groups postoperatively and both groups showed excellent clinical outcomes.
Discussion: The cuff integrity of the group S was better than that of the group L. The clinical results of the suture bridge technique were satisfactory in both groups, however 6 retears out of 15 shoulders were found in group L. Large traction force to the cuff in group L may cause cutout of the cuff edge in medial row before regeneration of footprint, since only sutures in the medial row were tied in the suture bridge technique.[Refereed]Scientific journal - (公社)日本整形外科学会, Aug. 2012, 日本整形外科学会雑誌, 86(8号) (8号), S1058 - S1058, Japaneseアテロコラーゲンを用いた細胞内アダプター蛋白Lnkの局所制御による血管・骨新生促進を介した骨折治療法[Refereed]Research society

Methods: The edges of the rotator cuff were harvested from patients who underwent arthroscopic rotator cuff repair, minced into pieces and cultured in a monolayer. We performed flow cytometric analyses to analyze cell surface markers. To induce multilineage differentiation, the cells were cultured in the osteogenic, adipogenic and chondrogenic differentiation media for 3 weeks. Then they were analyzed by histology, immunohistochemistry, and RT-PCR analyses.
Results: In flow cytometric analyses the cells were positive for MSC-related markers; CD29, CD44, CD105 and CD166. On the other hand, the cells were negative for hematopoietic-lineage markers; CD14, CD45 and CD133. After 3 weeks of differentiation culture the cells showed an osteogenic, adipogenic and chondrogenic potential as evidenced by the immunohistochemistry and RT-PCR analyses.
Discussion: This study showed that cells derived from the torn human rotator cuff have the capacity for multilineage mesenchymal differentiation. These results could have the way for tendon neoformation and regeneration using progenitor cells. The ability to generate bone-ligament interface is specifically of great importance, as it can be useful in healing torn tendons that require reattachment to bone. Further investigations for the mechanism of tenogenesis are necessary to find out.
Conclusion: The human rotator cuff derived cells have the capacity for multilineage differentiation and contribute to the repair of rotator cuff. - 2012, CELL TRANSPLANTATION, 21(8) (8), 1651 - 1665, English[Refereed]Scientific journal

- Transplantation of bone marrow (BM) CD34(+) cells, an endothelial/hematopoietic progenitor-enriched cell population, has shown therapeutic efficiency in the treatment of ischemic diseases enhancing neovascularization. However, the number of CD34(+) cells obtained from bone marrow is not sufficient for routine clinical application. To overcome this issue, we developed a more efficient and clinically applicable CD34(+) cell expansion method. Seven-day ex vivo expansion culture of BM CD34(+) cells with a cocktail of five growth factors containing VEGF, SCF, IL-6, Flt-3 ligand, and TPO resulted in reproducible more than 20-fold increase in cell number. The favorable effect of the local transplantation of culture expanded (cEx)-BM CD34(+) cells on rat unhealing fractures was equivalent or higher than that of nonexpanded (fresh) BM CD34(+) cells exhibiting sufficient therapeutic outcome with frequent vasculogenic/osteogenic differentiation of transplanted cEx-BM CD34(+) cells and fresh BM CD34(+) cells as well as intrinsic enhancement of angiogenesis/osteogenesis at the treated fracture sites. Specifically, cEx-BM CD34(+) cell treatment demonstrated the best blood flow recovery at fracture sites compared with the nonexpanded BM CD34(+) cells. In vitro, cEx-BM CD34(+) cells showed higher colony/tube-forming capacity than nonexpanded BM CD34(+) cells. Both cells demonstrated differentiation potential into osteoblasts. Since fresh BM CD34(+) cells can be easily collected from fracture sites at the time of primary operation and stored for future use, autologous cEx-BM CD34(+) cell transplantation would be not only a simple but also a promising therapeutic strategy for unhealing fractures in the field of orthopedic trauma surgery.2012, Cell transplantation, 21(12) (12), 2689 - 709, English, International magazine[Refereed]Scientific journal

- Failures in fracture healing after conventional autologous and allogenic bone grafting are mainly due to poor vascularization. To meet the clinical demand, recent attentions in the regeneration and repair of bone have been focused on the use of stem cells such as bone marrow mesenchymal stem cells and circulating skeletal stem cells. Circulating stem cells are currently paid a lot of attention due to their ease of clinical setting and high potential for osteogenesis and angiogenesis. In this report, we focus on the first proof-of-principle experiments demonstrating the collaborative characteristics of circulating CD34(+) cells, known as endothelial and hematopoietic progenitor cell-rich population, which are capable to differentiate into both endothelial cells and osteoblasts. Transplantation of circulating CD34(+) cells provides a favorable environment for fracture healing via angiogenesis/vasculogenesis and osteogenesis, finally leading to functional recovery from fracture. Based on a series of basic studies, we performed a phase 1/2 clinical trial of autologous CD34(+) cell transplantation in patients with tibial or femoral nonunions and reported the safety and efficacy of this novel therapy. In this review, the current concepts and strategies in circulating CD34(+) cell-based therapy and its potential applications for bone repair will be highlighted.Jun. 2014, Tissue Eng Part B Rev, 20(3) (3), 190 - 9, English, International magazine[Refereed]Introduction scientific journal

This time, we aimed to develop a preventive treatment for rotator cuff tear mainly caused by degeneration using various antioxidants (aposinine, nicotinamide mononucleotide; NMN, dehydroepiandrosterone; DHEA). First, AGEs were added to rat Achilles tendon cells to apply glycation stress, and each antioxidant was administered, and its anti-glycation and antioxidant effects were confirmed. Also, in animal experiments, a rat Achilles tendon degeneration or inflammation model was created, and each antioxidant was administered to the model, and the degeneration or inflammation inhibitory effect was confirmed.

Adipokines secreted from infiltrated adipocyte is known to contribute to chronic inflammation. We focused on Adiponectin, and evaluated its effect on chronic inflammation. We added Adiponectin to the muscle-derived cells cultured under inflammatory circumstances. Adiponectin showed the anti-inflammatory effect in this experiment. In in vivo experiment, muscle atrophy and fatty infiltration were observed in both torn tendon group and nerve damage group. The inflammatory cytokine was stimulated in atrophied and degenerated muscle. Simultaneously, Adiponectin was down-regulated in the endmysium of the atrophied muscle. Our results suggest that, in the atrophied and fatty infiltrated muscle caused by trauma such as tendon rupture and nerve damage, inflammation delays and chronic adipose inflammation would aggravate the clinical outcome.
