- BACKGROUND: Low-intensity pulsed ultrasound (LIPUS) is a non-invasive therapy that accelerates fracture healing. As a new treatment method for fracture, we recently reported that the transcutaneous application of CO2 accelerated fracture healing in association with promoting angiogenesis, blood flow, and endochondral ossification. We hypothesized that transcutaneous CO2 application, combined with LIPUS, would promote bone fracture healing more than the single treatment with either of them. METHODS: Femoral shaft fractures were produced in 12-week-old rats. Animals were randomly divided into four groups: the combination of CO2 and LIPUS, CO2, LIPUS, and control groups. As the transcutaneous CO2 application, the limb was sealed in a CO2-filled bag after applying hydrogel that promotes CO2 absorption. Transcutaneous CO2 application and LIPUS irradiation were performed for 20 min/day, 5 days/week. At weeks 1, 2, 3, and 4 after the fractures, we assessed the fracture healing process using radiography, histology, immunohistochemistry, real-time PCR, and biomechanical assessment. RESULTS: The fracture healing score using radiographs in the combination group was significantly higher than that in the control group at all time points and those in both the LIPUS and CO2 groups at weeks 1, 2, and 4. The degree of bone fracture healing in the histological assessment was significantly higher in the combination group than that in the control group at weeks 2, 3, and 4. In the immunohistochemical assessment, the vascular densities of CD31- and endomucin-positive microvessels in the combination group were significantly higher than those in the control and LIPUS groups at week 2. In the gene expression assessment, significant upregulation of runt-related transcription factor 2 (Runx2) and vascular endothelial growth factor (VEGF) was detected in the combination group compared to the LIPUS and CO2 monotherapy groups. In the biomechanical assessment, the ultimate stress was significantly higher in the combination group than in the LIPUS and CO2 groups. CONCLUSION: The combination therapy of transcutaneous CO2 application and LIPUS had a superior effect in promoting fracture healing through the promotion of angiogenesis and osteoblast differentiation compared to monotherapy.2024年10月, BMC musculoskeletal disorders, 25(1) (1), 863 - 863, 英語, 国際誌研究論文(学術雑誌)

- AIMS: Continuous local antibiotic perfusion (CLAP) has recently attracted attention as a new drug delivery system for orthopaedic infections. CLAP is a direct continuous infusion of high-concentration gentamicin (1,200 μg/ml) into the bone marrow. As it is a new system, its influence on the bone marrow is unknown. This study aimed to examine the effects of high-concentration antibiotics on human bone tissue-derived cells. METHODS: Cells were isolated from the bone tissue grafts collected from six patients using the Reamer-Irrigator-Aspirator system, and exposed to different gentamicin concentrations. Live cells rate, apoptosis rate, alkaline phosphatase (ALP) activity, expression of osteoblast-related genes, mineralization potential, and restoration of cell viability and ALP activity were examined by in vitro studies. RESULTS: The live cells rate (the ratio of total number of cells in the well plate to the absorbance-measured number of live cells) was significantly decreased at ≥ 500 μg/ml of gentamicin on day 14; apoptosis rate was significantly increased at ≥ 750 μg/ml, and ALP activity was significantly decreased at ≥ 750 μg/ml. Real-time reverse transcription-polymerase chain reaction results showed no significant decrease in the ALP and activating transcription factor 4 transcript levels at ≥ 1,000 μg/ml on day 7. Mineralization potential was significantly decreased at all concentrations. Restoration of cell viability was significantly decreased at 750 and 1,000 μg/ml on day 21 and at 500 μg/ml on day 28, and ALP activity was significantly decreased at 500 μg/ml on day 28. CONCLUSION: Our findings suggest that the exposure concentration and duration of antibiotic administration during CLAP could affect cell functions. However, further in vivo studies are needed to determine the optimal dose in a clinical setting.2024年03月, Bone & joint research, 13(3) (3), 91 - 100, 英語, 国際誌研究論文(学術雑誌)

- 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.

- Bone-modifying agents (BMAs), with bone-resorptive inhibitory effects, such as zoledronic acid and denosumab, are widely used at higher doses for bone-related events caused by bone metastasis of malignant tumors. These drugs have been suggested to be associated with atypical femoral fractures (AFFs), and the relationship between BMAs and AFFs has attracted attention. To investigate the clinical features including bone union time of AFFs in patients administered BMA for bone metastasis, we conducted a retrospective multicenter study. Thirty AFFs from 19 patients were enrolled in this study. Thirteen patients had bilateral AFFs, and nineteen AFFs had prodromal symptoms. Eighteen AFFs underwent surgery after complete fracture, three failed to achieve bone union and required nonunion surgery, and 11 AFFs that achieved bone union had an average period until bone union of 16.2 months, which was much longer than that previously reported for ordinary AFFs. Seven patients discontinued the BMAs, but not due to AFFs. Stopping BMAs in patients with bone metastasis would make it difficult to secure their performance of activities of daily living, and AFF with BMA administration might require a longer time for union. Therefore, it would be important to prevent incomplete AFF from becoming complete AFF via prophylactic internal fixation.2023年06月, Journal of bone oncology, 40, 100478 - 100478, 英語, 国際誌研究論文(学術雑誌)
- INTRODUCTION: The Masquelet technique is a relatively new method for large bone defect treatment. In this technique, grafted bone tissue is used, and after the cement is removed, the induced membrane (IM; that form around the cement spacers placed in the bone defect region) is thought to play an important role in promoting bone formation. On the other hand, low-intensity pulsed ultrasound (LIPUS) is known to promote fracture healing and angiogenesis through mechanical stimulation. This study aimed to investigate the in vitro effects of LIPUS on the osteogenic differentiation of human induced membrane-derived cells (IMCs). METHODS: Seven patients who had been treated using the Masquelet technique were enrolled. The IM was harvested during the second stage of the technique. IMCs were isolated, cultured in growth medium, and then divided into two groups: (1) control group, IMCs cultured in osteogenic medium without LIPUS, and (2) LIPUS group, IMCs cultured in osteogenic medium with LIPUS treatment. Adherent cells from the IM samples were harvested after the first passage and evaluated for cell surface protein expression using immunostaining. A cell proliferation assay was used to count the number of IMCs using a hemocytometer. Osteogenic differentiation capability was assessed using an alkaline phosphatase (ALP) activity assay, Alizarin Red S staining, and real-time reverse transcription-polymerase chain reaction. RESULTS: Cell surface antigen profiling revealed that the IMCs contained cells positive for the mesenchymal stem cell-related markers CD73, CD90, and CD105. No significant difference in cell numbers was found between the control and LIPUS groups. The ALP activity of IMCs in the LIPUS group was significantly higher than that in the control group on days 7 and 14. Alizarin red S staining intensity was significantly higher in the LIPUS group than in the control group on day 21. Runx2 and VEGF expression was significantly upregulated on days 7 and 14, respectively, compared with levels in the control group. CONCLUSION: We demonstrated the significant effect of LIPUS on the osteogenic differentiation of human IMCs. This study indicates that LIPUS can be used as an additional tool for the enhancement of the healing process of the Masquelet technique.2023年04月, Injury, 英語, 国際誌研究論文(学術雑誌)

- A Hoffa fracture is a rare type of femoral fracture that is difficult to treat. Nonoperative treatments usually result in failure; hence, in most cases, surgical treatments are essential. Nonunion following Hoffa fracture appears to be relatively uncommon, and there are limited reports in the literature about this type of nonunion. These reports suggest that open reduction and rigid internal fixation is the standard treatment for this type of nonunion. This study reports the case of a 61-year-old male patient who suffered from left lateral Hoffa fracture after falling from a truck bed. At the former hospital, open reduction and internal fixation were performed with plates and screws at 8 days post-injury. Postoperatively, displacement of the lateral proximal fragment was observed, and the patient reported left knee pain. Therefore, a revision open reduction and internal fixation was performed 4 months post-surgery. However, 6 months after the revision surgery, the patient reported instability and pain in the left knee, and subsequent radiography revealed nonunion of the fracture in the lateral condyle. The patient was referred to our hospital for further treatment. Treatment by re-revision open reduction and internal fixation was deemed challenging, and so rotating hinge knee (RHK) arthroplasty was performed as a salvage treatment. At 3 years post-surgery, no significant problems were observed, and the patient could walk without any assistance. The range of motion of the left knee was 0 to 100° without extension lag, and there was no lateral instability. Standard treatment for Hoffa fracture nonunion is commonly anatomical reduction and rigid internal fixation. However, total knee arthroplasty may be a better option for the treatment of Hoffa fracture nonunion in older patients.2023年03月, Cureus, 15(3) (3), e35780, 英語, 国際誌

- INTRODUCTION: Osteomyelitis pubis is a rare disease that presents with fever, pubic or hip pain, pain during hip movement, and claudication to avoid pain. It most frequently affects young athletes involved in sports that require twisting and cutting, but its exact cause is unknown and no definite treatment has been established. We report a case of pubic osteomyelitis in a young football player who was treated using the Masquelet technique and antibiotics with a good clinical course. CASE REPORTS: A 22-year-old male football player in a national-level university club team visited a nearby clinic complaining of high fever and mild pain in his bilateral hip joints. As a result of examination, we diagnosed osteomyelitis pubis and reconstructed the pubic symphysis by the Masquelet technique. In this case, the joint-like structure of the pubic symphysis was successfully reconstructed, and the patient was able to continue playing the sport. Three years and 3 months after surgery, he had no limitation of bilateral hip joint range of motion and did not display any symptoms while playing football. CONCLUSION: Masquelet technique could be a novel surgical method for managing osteomyelitis pubis, even in athletes.2022年12月, Journal of orthopaedic case reports, 12(12) (12), 39 - 42, 英語, 国際誌
- When visualizing biological activity at nonunion sites by the radioisotopes, gamma rays are more attenuated if metal implants are placed in the bone. However, the effects of various implant types and their placement on gamma ray attenuation in quantitative evaluation remain unknown. To elucidate these effects, we created a phantom that simulated the nonunion of the femur in this study. The count of gamma rays was measured by single-photon emission computed tomography/computed tomography (SPECT/CT) while considering CT-based attenuation correction (CTAC), metal implant placement, type (intramedullary nail or plate), and position. The count differed significantly with and without CTAC and with and without implants (both types) under CTAC. Significantly different counts were observed between the intramedullary nail and plate placed contralaterally to the lesion (i.e., non-lesion side). No significant difference was observed between the intramedullary nail and plate on the lesion side or between plates on the non-lesion and lesion sides. The measured standardized uptake value (SUV) was closer to the true SUV with CTAC than without. Moreover, the count was higher with implants than without. However, even with implants, it was lower than the actual count, indicating the absence of overcorrection. Implant type and position do not seem to influence the count.2022年11月, Journal of clinical medicine, 11(22) (22), 英語, 国際誌研究論文(学術雑誌)
- In this study, we examined the proliferation capability and osteogenic and chondrogenic differentiation potential of non-hypertrophic nonunion cells (NHNCs), and the effect of Escherichia coli-derived BMP-2 (E-BMP-2) on them. We enrolled five patients with non-hypertrophic nonunion. NHNCs isolated from nonunion tissue sampled during surgery were cultured, passaged, counted every 14 days, and analyzed. NHNCs were homogenous fibroblastic adherent cells and long-lived through at least 10 passages, with a slight decline. The cells were consistently positive for mesenchymal stem cell-related markers CD73 and CD105, and negative for the hematopoietic markers CD14 and CD45. NHNCs could differentiate into osteoblast lineage cells; however, they did not have strong calcification or sufficient chondrogenic differentiation capability. E-BMP-2 did not affect the proliferative capability of the cells but improved their osteogenic differentiation capability by increasing alkaline phosphatase activity and upregulating the gene expression of osterix, bone sialoprotein, and osteocalcin. E-BMP-2 enhanced their chondrogenic differentiation capability by upregulating the gene expression of aggrecan and collagen type II. We showed, for the first time, that NHNCs have the capacity to differentiate into osteoblast-lineage cells, although the chondrogenic differentiation potential was poor. Local application of E-BMP-2 with preservation of nonunion tissue is a potential treatment option for non-hypertrophic nonunion.2022年11月, Current issues in molecular biology, 44(11) (11), 5562 - 5578, 英語, 国際誌研究論文(学術雑誌)

- INTRODUCTION: The etiology of Klippel-Trenaunay syndrome (KTS) has a significant impact on the management of patient requiring surgical interventions. We report the strategies employed to address an infected non-union in a patient with KTS. CASE REPORT: The patient was transported to an initial treating hospital with femoral shaft fracture after experiencing a fall. The patient was diagnosed with KTS due to vascular malformations identified after severe intraoperative hemorrhaging. An open reduction and internal fixation was performed to stabilize the bone. Nine months after surgery, the patient was transferred to our hospital due to lack of healing with infected non-union. We prioritized treating the infection and plate displacement, and subsequently performed intramedullary nailing. Infection and intraoperative hemorrhaging were successfully controlled and bone union was confirmed 6 months after surgery. CONCLUSION: The key factors to minimize procedural complications are sufficient preoperative evaluation and planning, surgical skill, and perioperative resource management.2022年07月, Journal of orthopaedic case reports, 12(7) (7), 38 - 41, 英語, 国際誌

- For the prevention of surgical site infection (SSI), continuous disinfection could be helpful. Short wavelength ultraviolet radiation C (UVC) is highly bactericidal but shows cytotoxicity. Radiation of UVC with a wavelength of 222 nm to the skin is considered to be safe because it only reaches the stratum corneum. However, the safety of 222 nm irradiation to the surgical field not covered with skin is unknown. The purpose of this study was to examine the safety of 222 nm UVC irradiation on a surgical field in a rabbit model. Five types of tissue were surgically exposed and irradiated with 222 or 254 nm UVC. Immunohistological assessment against cyclobutane pyrimidine dimer (CPD), an index of DNA damage by UVC, was performed. The CPD-positive cell rate was significantly higher in the 254 nm group than in the other groups in all tissues. A 222 nm group showed significantly more CPD than control in fat tissue, but no significant difference in all other tissues. In fat tissue collected 24 h after irradiation, the 254 nm group showed higher CPD than the other groups, while the 222 nm group had reduced to the control level. These data suggest that 222 nm UVC irradiation could be a new method to safely prevent SSI.2022年03月, Photochemistry and photobiology, 98(6) (6), 1365 - 1371, 英語, 国際誌研究論文(学術雑誌)

- The use of induced pluripotent stem cells (iPSCs) shows potential in bone regenerative strategies. In this study, we investigated whether implantation of chondrogenically differentiated iPSC-derived mesenchymal stem cells (iMSCs) can lead to successful bone regeneration in nude mice with bone defects. Two human iPSC clones (201B7 and 454E2) were used. After generating iMSCs, chondrogenic differentiation was achieved by three-dimensional pellet culture. Thereafter, a 2-mm defect was created in the radius of nude mice, and chondrogenically differentiated iMSC pellets were transplanted in the defect. Microcomputed tomography imaging was performed 8 weeks posttransplantation to assess bone regeneration. All (100%) radii in the 201B7 cell-derived pellet transplantation group and 7 of 10 (70%) radii in the 454E2 cell-derived pellet transplantation group showed bone union. In contrast, 2 of 11 radii (18%) in the control group showed bone union. Thus, the experimental groups showed significantly higher bone union rates than the control group (p < 0.05). Histological analysis 2 weeks postimplantation in the experimental groups revealed hypertrophic chondrocytes within grafted iMSC pellets and the formation of woven bone around them. This hypertrophic chondrocyte transitioning to newly formed bone suggests that the cartilaginous template can trigger endochondral bone ossification (ECO). Four weeks postimplantation, the cartilage template was reduced in size; newly formed woven bone was predominant in the defect site. New vessels were surrounded by a matrix of woven bone, and hypertrophic chondrocytes transitioning to newly formed bone indicated the progression of ECO. Eight weeks postimplantation, the pellets were completely resorbed and replaced by bone; complete bone union was observed. Dense mature bone developed with evidence of lamellar-like bone formation. Collectively, our results suggest that using iMSC-based cartilage grafts recapitulating the morphogenetic process of ECO in the context of embryonic skeletogenesis is a promising strategy for repairing large bone defects. Impact statement We investigated whether implantation of chondrogenically differentiated iPSC-derived mesenchymal stem cells (iMSCs) could lead to the successful regeneration of bone defects in vivo. We implanted two different clones of human induced pluripotent stem cells into a radial bone defect model. Eleven of 11 (100%) and 7 of 10 (70%) radii in the 201B7 and 454E2 cell-derived pellet transplantation groups, respectively, showed bone union, which were significantly higher than those in the control group [only 2 of 11 radii (18%)]. Overall, our results support the use of iMSC-based cartilage grafts recapitulating the morphogenetic process of endochondral bone ossification for repairing large bone defects.2022年02月, Tissue engineering.

- Recently, reamer-irrigator-aspirator (RIA) systems have been increasingly used to harvest autologous bone grafts. RIA graft materials contain bone marrow, which provides a viable source to derive large numbers of mesenchymal stem cells. Low-intensity pulsed ultrasound (LIPUS) significantly accelerates the differentiation of stem cells derived from bone marrow. This in vitro study investigated the effect of LIPUS on the osteogenic activity and differentiation of RIA graft-derived cells. A small amount of RIA graft was obtained from seven patients. After the cells derived from RIA grafts were cultured, they were divided into two groups: the LIPUS and control groups. LIPUS was applied once daily for 20 min (1.5 MHz, pulse duration: 200 µs, pulse repetition rate: 1 kHz, spatial average-temporal average intensity: 30 mW/cm2). Alkaline phosphatase activity (113.4% and 130.1% on days 7 and 14), expression of osteoblast-related genes (ALP, Runx2) and mineralization (135.2% on day 21) of the RIA graft-derived cells were significantly higher in the LIPUS group than in the control group. However, LIPUS did not affect the cell proliferation of RIA graft-derived cells. This study indicates that LIPUS may enhance the healing of non-union and critical bone defects treated by autologous bone grafting using the RIA system.2022年02月, Ultrasound in medicine & biology, 48(2) (2), 313 - 322, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: Induced membrane (IM) is the key component of Masquelet reconstruction surgery for the treatment of bone defects. IM is formed around the cement spacer and is known to secrete growth factors and osteoinductive factors. However, there is limited evidence available concerning the presence of osteoinductive factors in IM. This study aimed to investigate the existence of bone morphogenetic proteins (BMPs) in IM harvested from patients during the treatment of bone defects using the Masquelet technique. METHODS: This study involved six patients whose bone defects had been treated using the Masquelet technique. The affected sites were the femur (n = 3) and the tibia (n = 3). During the second-stage surgery, 1 cm2 pieces of IM were harvested. Histological sections of IM were immunostained with anti-BMP-4, 6, 7, and 9 antibodies. Human bone tissue served as the positive control. RESULTS: The presence of BMP-4, 6, 7, and 9 was observed in all IM samples. Further, immunolocalization of BMP-4, 6, 7, and 9 was observed in blood vessels and fibroblasts in all IM samples. Immunolocalization of BMP-4, 6, 7, and 9 was also observed in bone tissue within the IM in one sample, in which osteogenesis inside the IM was observed. CONCLUSIONS: This study showed that osteoinductive factors BMP-4, 6, 7, and 9 were present in the IM harvested from patients, providing evidence indicating that the Masquelet technique effectively contributes to healing large bone defects. Therefore, it may be possible for surgeons to omit the addition of BMPs to bone grafts, given the endogenous secretion of BMPs from the IM.2022年01月, Journal of orthopaedic surgery and research, 17(1) (1), 29 - 29, 英語, 国際誌研究論文(学術雑誌)
- We introduce a treatment that combines the cross-leg free flap with the Masquelet technique and describe two cases using this method for bone and soft tissue reconstruction. Both patients were successfully treated and ambulatory. This novel method can be safely performed using the delay technique, indocyanine-green angiography and near-infrared spectroscopy.2022年, Case reports in plastic surgery & hand surgery, 9(1) (1), 99 - 104, 英語, 国際誌
- PURPOSE: Fracture-related infections are difficult to treat because of the formation of biofilms around implants. Systemic antibiotics are notoriously ineffective against biofilms due to their insufficient penetration of tissues with poor vascularity. The goal of treating fracture-related infections is to achieve bone union while retaining the implant. Our proposal of continuous local antibiotic perfusion is a sustained local delivery system of sufficient antibiotics to bone and soft tissue infection sites, including to bone marrow via needles as intra-medullary antibiotics perfusion and to soft-tissue via double-lumen subcutaneous tubes as intra-soft tissue perfusion. METHODS: In this study, we examined the outcomes of 40 patients treated for fracture-related infections using continuous local antibiotic perfusion between 2015 and 2021 at Steel Memorial Hirohata Hospital, Himeji, Japan. RESULT: The antibiotic used for continuous local antibiotic perfusion was gentamicin in all cases. Implant removal was required in five patients. Two patients required toe amputation and knee arthrodesis, while the remaining 38 patients achieved fracture union. Only one case of transient acute renal injury as a systemic side effect was observed, but it soon resolved. The blood concentration of gentamicin could be adjusted to less than the trough level. CONCLUSIONS: Continuous local antibiotic perfusion is a novel local drug delivery system that has the potential of delivering sufficient concentrations of antibiotics with few systemic side effects; it is a useful option for the treatment of fracture-related infections.2022年, Journal of orthopaedic surgery (Hong Kong), 30(2) (2), 10225536221111902 - 10225536221111902, 英語, 国際誌研究論文(学術雑誌)

- Introduction: We report a very rare case of nonunion with ballooning deformity of the humeral bone after a periprosthetic humeral fracture nonunion. Case Report: A 79-year-old woman underwent hemiarthroplasty 19 years ago for her proximal humerus fracture. She injured her right humeral diaphysis (stem distal end fracture) 6 years ago. She underwent revision hemiarthroplasty with long stem, but bony union was not obtained, and her right upper limb function was subsequently abolished due to extreme instability and pain in her right upper arm. She was then referred to our hospital for further treatment. X-ray showed nonunion in the humeral diaphysis and a severe ballooning deformity in the distal humeral bone fragment. Due to the advanced age and low activity of the patient, we chose total humerus replacement surgery instead of osteosynthesis. After the surgery, her upper arm pain and instability immediately improved. Three years after the last surgery, there have been no implant failures, and the upper arm is stable and painless. Conclusion: Although there are some reports of total humerus replacement as surgical treatment for humeral tumor and severe periprosthetic fracture, we found no reports of such ballooning deformity around the nonunion site. Total humerus replacement can be one of the treatment options in cases where nonunion surgery is extremely difficult, depending on the patient's age and activities of daily living.2022年01月, Journal of orthopaedic case reports, 12(1) (1), 89 - 91, 英語, 国際誌
- Introduction: Chronic osteomyelitis is difficult to cure definitively, because local areas are often covered with sequestrum and scar tissues with a poor blood flow; these may render systemic antibiotic administration ineffective. We present a case of chronic osteomyelitis that was successfully treated with continuous local antibiotic perfusion (CLAP) through an intramedullary antibiotic perfusion (iMAP) pin. Case Presentation: A 65-year-old man who suffered an episode of the right femoral osteomyelitis at the age of 15 years experienced a relapse at the age of 63 years. Systemic administration of antibiotics could not control the infection; thus, a surgery was performed. A bone marrow needle (i.e., an iMAP pin; diameter: 3 mm) was percutaneously inserted, from the front, distally and proximally to the cystic lesion in the distal femur. After washing through the iMAP pins, the pins were left indwelling. A closed drain tube was placed on the bone surface, which was close to the fistula of the bone marrow lesion. CLAP therapy was then initiated. Gentamicin was continuously infused through the iMAP pin at a rate of 2 mL/h and drained using the tube. Accordingly, 2.4 mg/mL, 1.2 mg/mL, and 1.2 mg/mL of gentamicin were administered for 4 days using two iMAP pins, for 5-8 days using two iMAP pins, and for 9-15 days using one iMAP pin, respectively, with a syringe pump. The iMAP pins and the drain tube were removed 15 days after the initiation of the CLAP therapy. The C-reactive protein level normalized 25 days postoperatively. The patient recovered full range of motion of the knee joint and recreational sports activity without recurrence of osteomyelitis for 5 years after the therapy. Conclusions: CLAP therapy allows local administration of a sufficient concentration of antibiotics and device removal after treatment is simple. This may be a novel treatment for chronic osteomyelitis.2021年12月, Journal of orthopaedic case reports, 11(12) (12), 35 - 38, 英語, 国際誌

- Current treatment options for osteoporosis primarily involve pharmacotherapies, but they are often accompanied by undesirable side effects. Utilization of mechanical stress which can noninvasively induce bone formation has been suggested as an alternative to conventional treatments. Here, we examined the efficacy of mechanical stress induced by electrical stimulation, radial extracorporeal shock waves, and ultrasound for estrogen-deficient osteoporosis. Female Wistar rats were divided into following five groups: sham-operated group, untreated after ovariectomy, and treated with electrical stimulation, radial extracorporeal shock wave, or ultrasound starting at 8 weeks after ovariectomy for 4 weeks. Trabecular bone architecture of the femur was assessed by micro-CT and its biomechanical properties were obtained by mechanical testing. The femurs were further evaluated by histochemical, immunohistochemical, and real-time PCR analyses. Radial extracorporeal shock wave and ultrasound treatment improved trabecular bone microarchitecture and bone strength in osteoporotic rats, but not electrical stimulation. The shock wave decreased osteoclast activity and RANKL expression. The exposure of ultrasound increased osteoblast activity and β-catenin-positive cells, and they decreased sclerostin-positive osteocytes. These findings suggest that mechanical stress induced by radial extracorporeal shock wave and ultrasound can improve estrogen-deficient bone loss and bone fragility through promoted bone formation or attenuated bone resorption.2021年08月, Calcified tissue international, 109(2) (2), 215 - 229, 英語, 国際誌研究論文(学術雑誌)

- Correct assessment of the bone healing process is required for the management of limb immobilization during the treatment of bone injuries, including fractures and defects. Although the monitoring of bone healing using ultrasound poses several advantages regarding cost and ionizing radiation exposure compared with other dominant imaging methods, such as radiography and computed tomography (CT), traditional ultrasound B-mode imaging lacks reliability and objectivity. However, the body structures can be quantitatively observed by ultrasound frequency-based methods, and therefore, the disadvantages of B-mode imaging can be overcome. In this study, we created a femoral bone hole model of a rat and observed the bone healing process using the quantitative ultrasound method and micro-CT, which provides a reliable assessment of the tissue microstructure of the bone. This study analyzed the correlation between these two assessments. The results revealed that the quantitative ultrasound measurements correlated with the CT measurements for rat bone healing. This ultrasound frequency-based method could have the potential to serve as a novel modality for quantitative monitoring of bone healing with the advantages of being less invasive and easily accessible. Impact statement Bone healing monitoring with ultrasound is advantageous as it is less invasive and easily accessible; however, the traditional B-mode method lacks reliability and objectivity. This study demonstrated that the proposed ultrasound frequency-based monitoring method can quantitatively observe bone healing and strongly correlates with the computed tomography measurements for rat bone healing. This method has the potential to become a reliable modality for monitoring bone healing.2021年06月, Tissue engineering. Part C, Methods, 27(6) (6), 349 - 356, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: Rich vascularity of the induced membrane (IM) is important for Masquelet reconstruction surgery. The factors affecting IM vascularity are not completely understood. This study aimed to investigate these factors using histological samples of human IMs. METHODS: We retrospectively evaluated 36 patients whose bone defects were treated using the Masquelet technique. Two clinical pathologists analyzed histological sections of IM pieces (1 cm2). The number of blood vessels per 1 mm2 was counted and compared among men and women, femur or tibia, with and without free flap surgery, antibiotic impregnation to the cement, osteogenesis inside the membrane, smoking, and diabetes mellitus. The number of blood vessels within the same patient was compared among different time points. Correlation analysis was performed among blood vessel numbers and patient age, duration of cement spacer placement, and histological grading scales (inflammation, foreign body reaction, and fibrosis). RESULTS: IM formation with rich vascularity and some inflammation, foreign body reaction, and fibrosis were histologically confirmed in all patients. We found 37.4 ± 19.1 blood vessels per 1 mm2. The number of blood vessels was significantly lower in patients with than in those without free flap surgery; it was higher in patients with osteogenesis inside the IM. No significant correlations were found in any of the analyses. CONCLUSION: Sex, patient age, smoking, diabetes mellitus, femur or tibia, duration of cement spacer placement, and antibiotic impregnation to the cement did not affect IM vascularization. IM vascularization was reduced in patients with than in those without free flap surgery.2021年04月, Journal of orthopaedic surgery and research, 16(1) (1), 248 - 248, 英語, 国際誌研究論文(学術雑誌)
- Introduction: Hypophosphatemic osteomalacia can be overlooked or confused with other musculoskeletal disorders due to the variety of associated clinical, laboratory, and radiographic findings. If osteomalacia is diagnosed early and the fractures are not displaced, they often heal with nutritional supplements, but, if they progress to displaced fractures, they may require surgical intervention. Case Report: We present a case of secondary osteomalacia due to autoimmune polyendocrine syndrome Type 2 due to this condition, the patient developed bilateral tibial proximal fractures and her varus deformity had progressed. No clear indication of the timing for surgery for adults with osteomalacia has been reported. However, medical treatment improves the symptoms of osteomalacia and it is reported that in children, appropriate level of the serum phosphate (P) should be attained and maintained for the successful bone healing after osteotomy. Therefore, we prioritized pharmacological treatment and prescribed surgery after confirming that the value of serum phosphate P had been improved to recommended levels (2.5-3.5 mg/dl). We performed high tibial osteotomy for the right side and gradual correction by an external fixation for the left tibia, because of more severe deformation, and converted to an internal fixation to shorten the treatment period. During conversion, we performed the operation with a locking plate by the minimal invasive plate osteosynthesis method (MIPO). Conclusion: We conclude that the use of different deformity correction methods, depending on the degree of deformity, and the pharmacological treatment of osteomalacia may lead to favorable results.2021年04月, Journal of orthopaedic case reports, 11(4) (4), 14 - 17, 英語, 国際誌

- Fractures associated with osteoporosis are a major public health concern. Current treatments for fractures are limited to surgery or fixation, leading to long-term bedrest, which is linked to increased mortality. Alternatively, utilization of physical agents has been suggested as a promising therapeutic approach for fractures. Here, we examined the effects of ultrasound, radial extracorporeal shock waves, and electrical stimulation on normal or osteoporotic fracture healing. Femoral bone defects were created in normal or ovariectomized rats. Rats were divided into four groups: untreated, and treated with ultrasound, shock waves, or electrical stimulation after surgery. Samples were collected at 2 or 4 weeks after surgery, and the healing process was evaluated with micro-CT, histological, and immunohistochemical analyses. Ultrasound at intensities of 0.5 and 1.0 W/cm2 , but not 0.05 W/cm2 , accelerated new bone formation. Shock wave exposure also increased newly formed bone, but formed abnormal periosteal callus around the defect site. Conversely, electrical stimulation did not affect the healing process. Ultrasound exposure increased osteoblast activity and cell proliferation and decreased sclerostin-positive osteocytes. We demonstrated that higher-intensity ultrasound and radial extracorporeal shock waves accelerate fracture healing, but shock wave treatment may increase the risk of periosteal callus formation.2021年02月, Annals of the New York Academy of Sciences, 1497(1) (1), 3 - 14, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: Recently, a standardized uptake value (SUV) has been used to evaluate bone single-photon emission computed tomography (SPECT). The aim of this study was to investigate quantitative SPECT imaging of uninfected nonunion to compare hypertrophic nonunion and non-hypertrophic nonunion using volume-based parameters. METHODS: We evaluated 23 patients with uninfected nonunion who underwent SPECT acquisition 3 h after an injection of 99mTc-hydroxymethylene diphosphonate or 99mTc-methylene diphosphonate from April 2014 to November 2019. We reconstructed the acquired data and performed voxel-based quantitative analysis using the GI-BONE software. Quantitative parameters, maximum SUV (SUVmax), peak SUV (SUVpeak), and mean SUV (SUVmean) in the high and low uptake areas of nonunion were compared between hypertrophic nonunion and non-hypertrophic nonunion. The contralateral limb was used as a control, and the ratios of the quantitative parameters were calculated. RESULTS: The values for the quantitative parameters (high uptake area/low uptake area, respectively), SUVmax control ratio (12.13 ± 4.95/6.44 ± 4.71), SUVpeak control ratio (11.65 ± 4.58/6.45 ± 4.64), and SUVmean control ratio (11.94 ± 5.03/6.28 ± 4.95) for hypertrophic nonunion were higher than those for non-hypertrophic nonunion (7.82 ± 4.76/3.41 ± 2.09 (p = 0.065/0.12), 7.56 ± 4.51/3.61 ± 2.23 (p = 0.065/0.22), and 7.59 ± 5.18/3.05 ± 1.91 (p = 0.076/0.23)). CONCLUSIONS: SUVmax, SUVpeak, and SUVmean control ratios obtained from bone SPECT images can quantitatively evaluate the biological activity of nonunions and may be an effective evaluation method for treatment decisions, especially the necessity of autologous bone grafting.2021年02月, Journal of orthopaedic surgery and research, 16(1) (1), 125 - 125, 英語, 国際誌研究論文(学術雑誌)
- PURPOSE: In our hospital, cases of bone and soft tissue infections have been treated with continuous local antibiotics perfusion that allows for continuous circulation of antibiotics throughout the infected lesion. We termed this treatment "intramedullary antibiotics perfusion (iMAP)" for bone infection such as fracture-related infection (FRI) and "intrasoft tissue antibiotics perfusion" for soft tissue infection. Many cases are treated with both modalities. To introduce iMAP, this study focused on the patients with FRI treated with iMAP and reviewed their treatment outcomes. METHODS: We included 10 patients with FRI treated with iMAP between 2004 and 2017. The iMAP needles were inserted near the infected lesion, and an aminoglycoside antimicrobial was continuously administered. Patient characteristics, pathogenic bacteria, administered antibiotics, duration of administration, concentrations of antibiotics in blood and leachate fluid, fracture union rate, implant retention rate, and complications were studied. RESULTS: The mean age of patients was 59.9 years, and the mean follow-up period was 2.5 years. Affected bones were the tibia (n = 8), humerus (n = 1), and fibula (n = 1). Deep infections developed on average 29.9 days after osteosynthesis. Pathogenic bacteria were methicillin-susceptible Staphylococcus aureus (n = 6), methicillin-resistant S. aureus (n = 2), and unknown (n = 2). Average iMAP duration was 17.1 days. In all patients, infection was eradicated while preserving the implants, and fracture union was achieved without complications. CONCLUSION: iMAP is a novel local drug delivery system allowing high concentrations of antibiotics to be administered without complications and is useful in the treatment of FRI.2021年, Journal of orthopaedic surgery (Hong Kong), 29(3) (3), 23094990211051492 - 23094990211051492, 英語, 国際誌研究論文(学術雑誌)

- Tumor-induced osteomalacia (TIO) is a rare skeletal disease caused by hypersecretion of fibroblast growth factor 23 (FGF-23) from neoplasms of mesenchymal origin; patients with TIO present with insufficiency fractures, progressive bone pain, and delayed fracture unions. Herein, we report the case of a 48-year-old man with an insufficiency fracture in his left femoral neck associated with TIO. The causative tumor located in the patient's maxillary sinus had been resected; however, complete resection was impossible due to the location of the tumor. Therefore, the patient's osteomalacia persisted, and he experienced a left femoral neck fracture in the absence of severe trauma. Because delayed fracture union was anticipated in this patient, we performed an internal fixation using an implant with a lateral plate for angular stability and multiple screws for rotational stability. Although fracture union took 15 months, the patient's postoperative course was uneventful, and he could walk without any symptoms or assistance at his most recent follow-up 30 months after surgery. In TIO, hypersecretion of FGF-23 leads to increased renal excretion of phosphorus, increased bone resorption of calcium and phosphorus, decreased osteoblastic bone mineralization, and decreased gastrointestinal absorption of calcium and phosphorus, leading to insufficiency fractures and delayed fracture unions. Diagnosis of TIO is often delayed due to its rarity and vague symptoms. Total resection of the causative tumor is the optimal treatment; however, in cases wherein complete tumor resection is impossible, drug therapy may be insufficient, and the underlying TIO pathology, including bone fragility, may persist. Early diagnosis of TIO is important for preventing insufficiency fractures; however, when fractures are unavoidable, the surgical treatment of femoral neck fractures in patients with osteomalacia should account for a longer time frame for complete fracture union and therefore utilize implants with sufficient stability.2021年, Case reports in orthopedics, 2021, 6668006 - 6668006, 英語, 国際誌

- 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年, Case reports in orthopedics, 2021, 5548729 - 5548729, 英語, 国際誌

- OBJECTIVE: Joint injury rapidly induces expression of primary response genes (PRGs), which activate a cascade of secondary genes that destroy joint tissues and initiate post-traumatic osteoarthritis (PTOA). Bromodomain-containing-protein-4 (Brd4) and cyclin-dependent-kinase-9 (CDK9) cooperatively control the rate-limiting step of PRG transactivation, including pro-inflammatory genes. This study investigated whether Brd4 and CDK9 inhibitors suppress inflammation and prevent PTOA development in vitro and in a mouse PTOA model. METHODS: The effects of Brd4 and CDK9 inhibitors (JQ1 and Flavopiridol) on PRG and associated secondary damage were rigorously tested in different settings. Short-term effects of inflammatory stimuli (IL-1β, IL-6, TNF) on human chondrocyte PRG expression were assessed by RT-PCR and microarray after 5-h. We quantified glycosaminoglycan release from IL-1β-treated bovine cartilage explants after 3-6 days, and osteoarthritic changes in mice after ACL-rupture using RT-PCR (2-24hrs), in vivo imaging of MMP activity (24hrs), AFM-nanoindentation (3-7days), and histology (3days-4wks). RESULTS: Flavopiridol and JQ1 inhibitors act synergistically, and a combination of both almost completely prevented the activation of most IL-1β-induced PRGs in vitro by microarray analysis, and prevented IL-1β-induced glycosaminoglycan release from cartilage explants. Mice given the drug combination showed reduced IL-1β and IL-6 expression, less in vivo MMP activity, and lower synovitis (1.5 vs 4.9) and OARSI scores (2.8 vs 6.0) than untreated mice with ACL-rupture. CONCLUSIONS: JQ1 and Flavopiridol work synergistically to reduce injury response after joint trauma, suggesting that targeting Brd4 and/or CDK9 could be a viable strategy for PTOA prevention and treatment of early OA.2021年01月, Osteoarthritis and cartilage, 29(1) (1), 68 - 77, 英語, 国際誌研究論文(学術雑誌)

- 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.2020年12月, BMJ open diabetes research & care, 8(2) (2), 英語, 国際誌研究論文(学術雑誌)

- 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.2020年09月, Journal of orthopaedic science : official journal of the Japanese Orthopaedic Association, 25(5) (5), 886 - 891, 英語, 国内誌[査読有り]研究論文(学術雑誌)

- BACKGROUND: Distraction osteogenesis has been broadly used to treat various structural bone deformities and defects. However, prolonged healing time remains a major problem. Various approaches including the use of low-intensity pulsed ultrasound, parathyroid hormone, and bone morphogenetic proteins (BMPs) have been studied to shorten the treatment period with limited success. Our previous studies of rats have reported that the transcutaneous application of CO2 accelerates fracture repair and bone-defect healing in rats by promoting angiogenesis, blood flow, and endochondral ossification. This therapy may also accelerate bone generation during distraction osteogenesis, but, to our knowledge, no study investigating CO2 therapy on distraction osteogenesis has been reported. QUESTIONS/PURPOSES: We aimed to investigate the effect of transcutaneous CO2 during distraction osteogenesis in rabbits, which are the most suitable animal as a distraction osteogenesis model for a lengthener in terms of limb size. We asked: Does transcutaneous CO2 during distraction osteogenesis alter (1) radiographic bone density in the distraction gap during healing; (2) callus parameters, including callus bone mineral content, volumetric bone mineral density, and bone volume fraction; (3) the newly formed bone area, cartilage area, and angiogenesis, as well as the expression of interleukin-6 (IL-6), BMP-2, BMP-7, hypoxia-inducible factor (HIF) -1α, and vascular endothelial growth factor (VEGF); and (4) three-point bend biomechanical strength, stiffness, and energy? METHODS: Forty 24-week-old female New Zealand white rabbits were used according to a research protocol approved by our institutional ethical committee. A distraction osteogenesis rabbit tibia model was created as previously described. Briefly, an external lengthener was applied to the right tibia, and a transverse osteotomy was performed at the mid-shaft. The osteotomy stumps were connected by adjusting the fixator to make no gap. After a 7-day latency phase, distraction was continued at 1 mm per day for 10 days. Beginning the day after the osteotomy, a 20-minute transcutaneous application of CO2 on the operated leg using a CO2 absorption-enhancing hydrogel was performed five times per week in the CO2 group (n = 20). Sham treatment with air was administered in the control group (n = 20). Animals were euthanized immediately after the distraction period (n = 10), 2 weeks (n = 10), and 4 weeks (n = 20) after completion of distraction. We performed bone density quantification on the plain radiographs to evaluate consolidation in the distraction gap with image analyzing software. Callus parameters were measured with micro-CT to assess callus microstructure. The newly formed bone area and cartilage area were measured histologically with safranin O/fast green staining to assess the progress of ossification. We also performed immunohistochemical staining of endothelial cells with fluorescein-labeled isolectin B4 and examined capillary density to evaluate angiogenesis. Gene expressions in newly generated callus were analyzed by real-time polymerase chain reaction. Biomechanical strength, stiffness, and energy were determined from a three-point bend test to assess the mechanical strength of the callus. RESULTS: Radiographs showed higher pixel values in the distracted area in the CO2 group than the control group at Week 4 of the consolidation phase (0.98 ± 0.11 [95% confidence interval 0.89 to 1.06] versus 1.19 ± 0.23 [95% CI 1.05 to 1.34]; p = 0.013). Micro-CT demonstrated that bone volume fraction in the CO2 group was higher than that in the control group at Week 4 (5.56 ± 3.21 % [95% CI 4.32 to 6.12 %] versus 11.90 ± 3.33 % [95% CI 9.63 to 14.25 %]; p = 0.035). There were no differences in any other parameters (that is, callus bone mineral content at Weeks 2 and 4; volumetric bone mineral density at Weeks 2 and 4; bone volume fraction at Week 2). At Week 2, rabbits in the CO2 group had a larger cartilage area compared with those in the control group (2.09 ± 1.34 mm [95% CI 1.26 to 2.92 mm] versus 5.10 ± 3.91 mm [95% CI 2.68 to 7.52 mm]; p = 0.011). More newly formed bone was observed in the CO2 group than the control group at Week 4 (68.31 ± 16.32 mm [95% CI 58.19 to 78.44 mm] versus 96.26 ± 19.37 mm [95% CI 84.25 to 108.26 mm]; p < 0.001). There were no differences in any other parameters (cartilage area at Weeks 0 and 4; newly formed bone area at Weeks 0 and 2). Immunohistochemical isolectin B4 staining showed greater capillary densities in rabbits in the CO2 group than the control group in the distraction area at Week 0 and surrounding tissue at Weeks 0 and 2 (distraction area at Week 0, 286.54 ± 61.55 /mm [95% CI 232.58 to 340.49] versus 410.24 ± 55.29 /mm [95% CI 361.78 to 458.71]; p < 0.001; surrounding tissue at Week 0 395.09 ± 68.16/mm [95% CI 335.34 to 454.83] versus 589.75 ± 174.42/mm [95% CI 436.86 to 742.64]; p = 0.003; at Week 2 271.22 ± 169.42 /mm [95% CI 122.71 to 419.73] versus 508.46 ± 49.06/mm [95% CI 465.45 to 551.47]; p < 0.001 respectively). There was no difference in the distraction area at Week 2. The expressions of BMP -2 at Week 2, HIF1-α at Week 2 and VEGF at Week 0 and 2 were greater in the CO2 group than in the control group (BMP -2 at Week 2 3.84 ± 0.83 fold [95% CI 3.11 to 4.58] versus 7.32 ± 1.63 fold [95% CI 5.88 to 8.75]; p < 0.001; HIF1-α at Week 2, 10.49 ± 2.93 fold [95% CI 7.91 to 13.06] versus 20.74 ± 11.01 fold [95% CI 11.09 to 30.40]; p < 0.001; VEGF at Week 0 4.80 ± 1.56 fold [95% CI 3.43 to 6.18] versus 11.36 ± 4.82 fold [95% CI 7.13 to 15.59]; p < 0.001; at Week 2 31.52 ± 8.26 fold [95% CI 24.27 to 38.76] versus 51.05 ± 15.52 fold [95% CI 37.44 to 64.66]; p = 0.034, respectively). There were no differences in any other parameters (BMP-2 at Week 0 and 4; BMP -7 at Weeks 0, 2 and 4; HIF-1α at Weeks 0 and 4; IL-6 at Weeks 0, 2 and 4; VEGF at Week 4). In the biomechanical assessment, ultimate stress and failure energy were greater in the CO2 group than in the control group at Week 4 (ultimate stress 259.96 ± 74.33 N [95% CI 167.66 to 352.25] versus 422.45 ± 99.32 N [95% CI 299.13 to 545.77]; p < 0.001, failure energy 311.32 ± 99.01 Nmm [95% CI 188.37 to 434.25] versus 954.97 ± 484.39 Nmm [95% CI 353.51 to 1556.42]; p = 0.003, respectively). There was no difference in stiffness (216.77 ± 143.39 N/mm [95% CI 38.73 to 394.81] versus 223.68 ± 122.17 N/mm [95% CI 71.99 to 375.37]; p = 0.92). CONCLUSION: Transcutaneous application of CO2 accelerated bone generation in a distraction osteogenesis model of rabbit tibias. As demonstrated in previous studies, CO2 treatment might affect bone regeneration in distraction osteogenesis by promoting angiogenesis, blood flow, and endochondral ossification. CLINICAL RELEVANCE: The use of the transcutaneous application of CO2 may open new possibilities for shortening healing time in patients with distraction osteogenesis. However, a deeper insight into the mechanism of CO2 in the local tissue is required before it can be used in future clinical practice.2020年08月, Clinical orthopaedics and related research, 478(8) (8), 1922 - 1935, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: A reamer irrigator aspirator (RIA) can be used to harvest substantial amounts of autologous bone and debride the intramedullary canal. Clinical experience using reamer irrigator aspirators in Japan is very limited. The applicability of the reamer irrigator aspirator head with a minimum diameter of 12 mm for Japanese people is often questioned as the Japanese are smaller than Americans and Europeans. There are no reports of complications in Japanese patients. This study aimed to retrospectively review clinical cases and describe reamer irrigator aspirator use in Japanese patients. METHODS: All patients for whom a reamer irrigator aspirator was used during surgery at our hospital between January 2014 and September 2018 were included. The patients' clinical and radiographic data were retrospectively reviewed. RESULTS: Data of 40 patients (42 cases) were collected. The reamer irrigator aspirator was used for bone graft harvesting in 32 cases, intramedullary debridement and irrigation in 9 cases, and reaming for exchange nailing in 1 case. The diameter of the reamer irrigator aspirator reamer head was 12 mm in 22 cases (53.7%), 12.5 mm in 4 cases (9.8%), 13 mm in 9 cases (22.0%), 13.5 mm in 1 case (2.4%), 14.0 mm in 1 case (2.4%), 14.5 mm in 1 case (2.4%), and 15 mm in 4 cases (9.8%). Mean intraoperative bleeding volume was 1158.6 mL (range, 100-3800 mL). We experienced no difficulty inserting the reamer irrigator aspirator into the intramedullary canals and no cases of insertion-related intraoperative fracture. Five cortical perforations (11.9%) were observed on postoperative computed tomography scans, although no patient was symptomatic. One case (2.4%) of postoperative femur fracture occurred. CONCLUSIONS: Reamer irrigator aspirators can be used in Japanese patients. Smaller reamer head sizes were mainly used in our experience. We should manage complications as in previous reports from Western countries.2020年05月, Journal of orthopaedic science : official journal of the Japanese Orthopaedic Association, 26(3) (3), 459 - 465, 英語, 国内誌研究論文(学術雑誌)
- BACKGROUND: MicroRNAs (miRNAs) are a class of small non-coding RNA molecules that regulate gene expression. There is increasing evidence that some miRNAs are involved in the pathology of diabetes mellitus (DM) and its complications. We hypothesized that the functions of certain miRNAs and the changes in their patterns of expression may contribute to the pathogenesis of impaired fractures due to DM. METHODS: In this study, 108 male Sprague-Dawley rats were divided into DM and control groups. DM rats were created by a single intravenous injection of streptozotocin. Closed transverse femoral shaft fractures were created in both groups. On post-fracture days 5, 7, 11, 14, 21, and 28, miRNA was extracted from the newly generated tissue at the fracture site. Microarray analysis was conducted with miRNA samples from each group on post-fracture days 5 and 11. The microarray findings were validated by real-time polymerase chain reaction (PCR) analysis at each time point. RESULTS: Microarray analysis revealed that, on days 5 and 11, 368 and 207 miRNAs, respectively, were upregulated in the DM group, compared with the control group. The top four miRNAs on day 5 were miR-339-3p, miR451-5p, miR-532-5p, and miR-551b-3p. The top four miRNAs on day 11 were miR-221-3p, miR376a-3p, miR-379-3p, and miR-379-5p. Among these miRNAs, miR-221-3p, miR-339-3p, miR-376a-3p, miR-379-5p, and miR-451-5p were validated by real-time PCR analysis. Furthermore, PCR analysis revealed that these five miRNAs were differentially expressed with dynamic expression patterns during fracture healing in the DM group, compared with the control group. CONCLUSIONS: Our findings will aid in understanding the pathology of impaired fracture healing in DM and may support the development of molecular therapies using miRNAs for the treatment of impaired fracture healing in patients with DM.2020年04月, Journal of orthopaedic surgery and research, 15(1) (1), 135 - 135, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Introduction: It remains controversial whether amputation or limb salvage is the best approach for mangled foot cases because there are no clear criteria for treatment. We report a case of successful limb salvage for a mangled foot, with good outcomes. Case Report: The patient was a 30-year-old man who sustained a crush injury to his left foot and ankle and lower legs in a car crash; he had severe open left foot and ankle fracture and bilateral open tibial shaft fractures. Blood flow was maintained by the posterior tibial artery, and the tibial nerve was intact. We stabilized the ankle using Kirschner wires on the day of injury. Plastic surgeons were consulted for early soft tissue coverage. Final fixation was performed 12 weeks after flap grafting; we grafted an autologous bone on the defect, according to the Masquelet technique. Four months after the final surgery, fullweightbearing gait was initiated. The patient is now capable of walking independently, with no pain, and is highly satisfied. Conclusions: Limb salvage can be successfully performed even in a patient with a severely mangled foot. For successful salvage surgery with good outcomes, such patients should be managed by a team of experienced orthopedic and plastic surgeons from an early stage to achieve appropriate bone alignment and soft tissue coverage.2020年, Journal of orthopaedic case reports, 9(6) (6), 58 - 61, 英語, 国際誌
- A 14-year-old girl experienced acute left buttock pain during a sprint. At the local hospital, she was diagnosed with an avulsion fracture of the left ischial tuberosity. She was kept for observation for about 10 months; however, the buttock pain persisted, and the bone fragments did not unite. She was referred to our hospital approximately 11 months after the injury. Plain radiography revealed an increased transposition of the bone fragment, from 12 mm immediately after the injury to 23 mm. Twelve months after the injury, she underwent osteosynthesis using two cannulated cancellous screws and three suture anchors. Following postoperative rehabilitation, the power in her left hamstring recovered, and she was able to run at full speed and returned to athletics 9 months after the surgery. The operative indications for avulsion fractures of the ischial tuberosity are unclear. Careful follow-up is required as the rate of nonunion after conservative treatment tends to be high. This needs to be identified in order to provide timely treatment that allows for early return to sport. Although she had significant chronic pain and muscle weakness, the surgery successfully treated the fracture, and her muscle power recovered, leading to her return to sports.2020年, Case reports in orthopedics, 2020, 8531648 - 8531648, 英語, 国際誌
- INTRODUCTION: Surgical site infection is one of the most severe complications of surgical treatments. However, the optimal procedure to prevent such infections remains uninvestigated. Ultraviolet radiation C (UVC) with a short wavelength has a high bactericidal effect; however, it is cytotoxic. Nonetheless, given that UVC with a wavelength of 222 nm reaches only the stratum corneum, it does not affect the skin cells. This study aimed to investigate the safety of 222-nm UVC irradiation and to examine its skin sterilization effect in healthy volunteers. METHODS: This trial was conducted on 20 healthy volunteers. The back of the subject was irradiated with 222-nm UVC at 50-500 mJ/cm2, and the induced erythema (redness of skin) was evaluated. Subsequently, the back was irradiated with a maximum amount of UVC not causing erythema, and the skin swabs before and after the irradiation were cultured. The number of colonies formed after 24 hours was measured. In addition, cyclobutene pyrimidine dimer (CPD) as an indicator of DNA damage was measured using skin tissues of the nonirradiated and irradiated regions. RESULTS: All subjects experienced no erythema at all doses. The back of the subject was irradiated at 500 mJ/cm2, and the number of bacterial colonies in the skin swab culture was significantly decreased by 222-nm UVC irradiation. The CPD amount produced in the irradiated region was slightly but significantly higher than that of the non-irradiated region. CONCLUSION: A 222-nm UVC at 500 mJ/cm2 was a safe irradiation dose and possessed bactericidal effects. In the future, 222-nm UVC irradiation is expected to contribute to the prevention of perioperative infection.2020年, PloS one, 15(8) (8), e0235948, 英語, 国際誌研究論文(学術雑誌)
- 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.2019年12月, BMC musculoskeletal disorders, 20(1) (1), 602 - 602, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- 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.2019年12月, Annals of medicine and surgery (2012), 48, 43 - 47, 英語, 国際誌[査読有り]
- BACKGROUND: Clinicians have very limited options to improve fracture repair. Therefore, it is critical to develop a new clinically available therapeutic option to assist fracture repair biologically. We previously reported that the topical cutaneous application of carbon dioxide (CO2) via a CO2 absorption-enhancing hydrogel accelerates fracture repair in rats by increasing blood flow and angiogenesis and promoting endochondral ossification. The aim of this study was to assess the safety and efficacy of CO2 therapy in patients with fractures. METHODS: Patients with fractures of the femur and tibia were prospectively enrolled into this study with ethical approval and informed consent. The CO2 absorption-enhancing hydrogel was applied to the fractured lower limbs of patients, and then 100% CO2 was administered daily into a sealed space for 20 min over 4 weeks postoperatively. Safety was assessed based on vital signs, blood parameters, adverse events, and arterial and expired gas analyses. As the efficacy outcome, blood flow at the level of the fracture site and at a site 5 cm from the fracture in the affected limb was measured using a laser Doppler blood flow meter. RESULTS: Nineteen patients were subjected to complete analysis. No adverse events were observed. Arterial and expired gas analyses revealed no adverse systemic effects including hypercapnia. The mean ratio of blood flow 20 min after CO2 therapy compared with the pre-treatment level increased by approximately 2-fold in a time-dependent manner. CONCLUSIONS: The findings of the present study revealed that CO2 therapy is safe to apply to human patients and that it can enhance blood flow in the fractured limbs.

- Although the definition of atypical femoral fracture (AFF) excludes periprosthetic femoral fracture (PFF), the number of reports about PFF with characteristics of AFF is increasing. We present the case of such a fracture in this report. An 87-year-old woman who underwent bipolar hip arthroplasty for a femoral neck fracture 38 months prior reported left thigh pain with no history of trauma. Radiographs showed a simple transverse fracture at the level of the stem distal end with features of AFF: periosteal thickening of the lateral cortex, a medial spike, and a noncomminuted fracture. She presented other features resembling AFF: history of bisphosphonate use, prodromal symptoms, no associated trauma, and lateral bowing of the contralateral femur. The fracture showed nonunion after the initial osteosynthesis, and a revision surgery of the arthroplasty and osteosynthesis was performed. Nine months after the surgery, bony union was achieved and she regained the ability to walk. It is supposed that the fracture was influenced by a stress force related to implants and lateral bowing concentrating on the fracture site as a mechanical factor in addition to bisphosphonates as a biological factor. It would be important to recognize that AFF could occur at the peri-implant location, and early detection and treatment are essential.2019年, Case reports in orthopedics, 2019, 1275369 - 1275369, 英語, 国際誌[査読有り]
- Introduction: Osteogenesis imperfecta (OI) is a heritable disorder of connective tissue. Due to poor bone quality, patients with OI develop bone fracture and subsequent non-union at high rates. We report the rare case of humeral shaft non-union successfully treated by a locking plate used formandibular bone in a patient with OI. Case Report: A 26-year-old man with Type III OI and a history of corrective osteotomy with Kirschner wire fixation of his right humerus at the age of 8 years developed gradually increasing pain in his humerus. He sustained humeral shaft non-union due to a broken Kirschner wire used in the previous operation and was referred to our hospital. He underwent internal fixation using an elastic nail with an iliac bone graft. However, 2 years after the operation, bony union was not achieved due to elastic nail breakage, and he complained of pain and activity limitation. He underwent re-operation for the humeral non-union using a locking plate to achieve rigid fixation. Because his humeral shaft was extremely narrow with severe deformity, we used a locking plate for the mandibular bone, which was contoured to fit the medial side of the humeral shaft. Bony union was achieved, the pain was relieved, and the patient returned to his pre-injury activity with no symptoms.4years after the operation, a new fracture line was found in radiographs of the distal part of the non-union. Bony union was achieved by conservative treatment. At present, the function has recovered. Conclusion: Humeral non-union in this patient with OI was successfully treated by a mandible locking plate. Although the optimal fixation device for fractures or non-unions in patients with OI has not yet been established, this plate could be a good treatment option for narrow and severely deformed bone.2019年, Journal of orthopaedic case reports, 9(3) (3), 19 - 21, 英語, 国際誌[査読有り]

- Rotational malreduction is a potential complication of intramedullary nailing for tibial shaft fractures. We experienced a symptomatic case of a 24° externally rotated malunion that we treated with minimally invasive corrective osteotomy. A 49-year-old man sustained a tibial shaft spiral fracture with a fibula fracture. He had been initially treated elsewhere with a reamed statically locked intramedullary nail. Bone union had been obtained, but he complained of asymmetry of his legs, difficulty walking and running, and the inability to ride a bicycle. We decided to perform corrective osteotomy in a minimally invasive fashion. After a 1 cm incision was made at the original fracture site, osteotomy for the affected tibia was performed with an osteotome after multiple efforts at drilling around the nail with the aim of retaining it. Fibula osteotomy was also performed at the same level. Two Kirschner wires that created an affected rotational angle between the fragments were inserted as a guide for correction. The distal locking screws were removed. Correct rotation was regained by matching the two wires in a straight line. Finally, the distal locking screws were inserted into new holes. The patient obtained bony union and has returned to his preinjury activities with no symptoms.Hindawi Limited, 2018年, Case reports in orthopedics, 2018, 4190670 - 4190670, 英語, 国際誌[査読有り]

- OBJECTIVE: The aim of this study was to report the clinical results of atypical femoral fractures (AFFs) treated with low-intensity pulsed ultrasound (LIPUS). MATERIALS AND METHODS: The data on AFFs that were surgically treated in our hospital from 2010 to 2016 was retrospectively analyzed. AFF was diagnosed based on the criteria defined by the second report of an ASBMR task force. RESULTS: Seven fractures in 6 cases were included in this study. Two fractures were referred to us as being nonunion. Five fractures were subtrochanteric fractures and 2 fractures were shaft fractures. Five fresh AFFs were fixed with an intramedullary nail and 2 nonunion fractures were fixed with plates. LIPUS was used in 6 fractures. Bone union was achieved in 5 fractures with the average time to union being 17 months (5-29). In 4 out of the 6 fractures treated with LIPUS, bone union was achieved after 14 months on average. In the other 2 LIPUS-treated fractures, bone union was not achieved even at 1 year after surgery. DISCUSSION: It is known that AFF healing tends to be very slow. Some case reports indicate that AFF healing might be accelerated by LIPUS. In the current series, the subtrochanteric fracture that was not treated with LIPUS healed at 29 months after surgery, which was much longer than the average time to union in the 5 fractures that were treated with LIPUS. Although our number of cases is small, LIPUS may be a potentially useful tool for accelerating AFF repair.2017年07月, Journal of orthopaedic trauma, 31(7) (7), S2, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Fibrous dysplasia (FD) is an uncommon, but well-known benign skeletal disorder. In cases affecting long bones, FD is commonly recognized to locate in the diaphyses or the metaphyses and to spare the epiphyses. In this paper, we present a rare case of polyostotic FD in a 13-year-old girl with unilateral multiple epiphyseal lesions arising in the femur, the tibia, and the fibula with the growth plates.2013年, Case reports in orthopedics, 2013, 715402 - 715402, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- 膝蓋骨 malalignment に対する内側膝蓋大腿靭帯 (MPFL) 再建術の術後成績Many surgical techniques have been reported for the treatment of malalignment of patella. Over recent years, as the medial patellofemoral ligament (MPFL) has been shown to be the primary restraint to lateral patellar translation, MPFL reconstruction has become a common procedure. The purpose of this study was to investigate the short term results of 8 cases (4 men, 4 women, mean age 22.8 years), who underwent MPFL reconstruction in our hospital using hamstring tendons. Mean follow-up period was 1.7 years. The mean Kujala score improved from preoperative 55.6 points to postoperative 95.5 points, with no occurrence of patella apprehension. Furthermore, patellofemoral alignment improved after surgery in all cases. Based on these results, we concluded that MPFL reconstruction is useful for the treatment of patella malalignment.中国・四国整形外科学会, 2007年, 中国・四国整形外科学会雑誌, 19(1) (1), 27 - 31, 日本語

- 日本学術振興会, 科学研究費助成事業 基盤研究(C), 基盤研究(C), 神戸大学, 2021年04月01日 - 2025年03月31日炭酸ガスを利用したロコモティブシンドロームに対する新たな予防・治療法の開発加齢に伴い骨粗鬆症と骨脆弱性骨折のリスクは増大する。これは閉経後の女性で顕著であり、現在骨粗鬆症に対しては薬物治療が一般的である。我々はこれまでに炭酸ガス経皮吸収が、局所組織内の酸素化、血流増加、血管新生を介し、骨折治癒の促進や破骨細胞活性の抑制効果を有する事を報告してきた。本研究の目的の一つは、卵巣摘出(OVX)ラット骨粗鬆症モデルを用いて、炭酸ガス経皮吸収システムにより骨粗鬆症の病態が改善するかを検討する事である。 12週齢の雌ラットを用い、両側OVXを施行し骨粗鬆症モデルを作成した。これらを炭酸ガス経皮吸収群、対照群の二群に分け、炭酸ガス群に対してはOVX術後翌日より炭酸ガス投与を開始する実験系(骨粗鬆症の予防を検討)と、OVX術後8週経過してから炭酸ガス投与を開始する実験系(骨粗鬆症の治療を検討)の二通りの実験系を組んだ。炭酸ガス経皮吸収は1日20分間、週5日行った。対照群に対しては同様のゲルを塗布しポリエチレン袋にて密閉するのみとした。両群において、炭酸ガス経皮吸収開始後8週マイクロCTを用いて大腿骨遠位部の骨量などのパラメータを比較した。現在、各実験系の各群において5サンプルずつの介入が終了し評価を行ったが両群間に有意差は認めていない。 また、今後の研究に密接に関わってくると考えられることから、炭酸ガス経皮吸収の至適治療時間についての検討も行っている。ラット大腿骨骨折モデルを作成し、従来の20分投与に加え、60分投与の群を設定した。頻度は上記と同じく週5日としている。骨折作成後4週までの毎週のレントゲン撮影を終了しており、順次データ解析予定である。また、同様のタイムポイントでの組織評価用のサンプル採取を完了しており、切片作製予定である。さらに、術後2・3週での骨遺伝子学的検討と免疫組織学的検討を行うためのサンプル採取と、術後4週での骨密度評価を行う予定としている。

- 日本学術振興会, 科学研究費助成事業 基盤研究(C), 基盤研究(C), 神戸大学, 2017年04月01日 - 2020年03月31日【背景】外傷や骨感染症、骨腫瘍により骨を失った患者に対して骨延長術は有用で確立された治療法であるが、長い治療期間を必要とすることが欠点である。我々はこれまでにラット大腿骨骨折モデルにおいて、炭酸ガス経皮吸収療法により骨折治癒が加速されるという知見を得ている。本研究では、骨延長術に炭酸ガス経皮吸収療法を組み合わせることで、骨形成が促進し、治療期間が短縮されるかを検証した。 【目的】骨延長術に炭酸ガス経皮吸収を応用することで骨再生を促進できるという仮説を検証することを、平成29年度から30年度にわたる研究目的とした。 【方法】24週齢、メスのNew Zealand white rabbitを使用した。片側脛骨に創外固定器を装着、骨幹部で骨切りを行い、1週間の待機期間を置いた後、1日1mm、計10mmの骨延長を行った。患側下肢に炭酸ガス経皮吸収促進効果を有するハイドロジェルを塗布し、1日20分間、週5日間、炭酸ガスを経皮吸収させた。延長完了時、完了後2週、4週で安楽死させ、経皮吸収を行った炭酸ガス群20羽と行わなかった対照群20羽で、骨形成をX線学的、組織学的に、また、骨強度を力学試験にて評価し、比較検討を行った。 【結果】単純X線撮影を行い、画像解析ソフトを用いて骨形成の程度を定量化したところ、炭酸ガス群では延長完了後4週で延長部のピクセル値が有意に高かった。組織学的評価では炭酸ガス群で、延長完了後2週での軟骨形成が旺盛であり、延長完了時および延長完了後2週で新生血管数が有意に多かった。マイクロCT評価では延長完了後2週において延長仮骨の骨塩量と骨梁幅が炭酸ガス群で有意に高値であった。延長完了後4週に行った力学試験では炭酸ガス群で破断エネルギーが有意に高かった。 【考察】炭酸ガス経皮吸収は、骨延長術における骨形成を促進する有用な併用療法として臨床応用が期待できる可能性を示せた。競争的資金
- 日本学術振興会, 科学研究費助成事業 基盤研究(C), 基盤研究(C), 神戸大学, 2017年04月01日 - 2020年03月31日糖尿病患者では骨折後の骨癒合不全の発生頻度が高く、長期間の治療を要することが知られている。糖尿病動物モデルを用いた研究で、軟骨内骨化の阻害がその一因であることが証明されている。我々はこれまでに、炭酸ガスを経皮吸収させることで軟骨内骨化が促進され骨折治癒が進行することをラット大腿骨骨折モデルで証明した。炭酸ガス経皮吸収が糖尿病動物モデルにおいても同様の機序で骨折治癒を進行させる可能性が高いと考えられる。本研究の目的は、糖尿病動物モデルにおいて炭酸ガス経皮吸収が骨折治癒を進行させるかを検討することである。 12週齢、雌のstreptozotocin誘発1型糖尿病ラットの大腿骨に閉鎖性大腿骨横骨折モデルを作成する。炭酸ガスを週5回投与する炭酸ガス群(炭酸ガス群)と、対照群(炭酸ガス非吸収群)の2群に分け、炭酸ガス群には、骨折肢に炭酸ガス経皮吸収促進ゲルを塗布し、袋で密閉して1日1回20分間100%炭酸ガスを経皮吸収させた。対照群には、同ゲルを骨折肢に塗布するのみとした。 骨折作成後1、2、3、4週で骨癒合評価、組織学的評価、real time PCRを用いた遺伝子学的評価を、骨折作成後4週の時点で三点曲げ試験による骨強度評価を行った。 単純X線像で骨折作成後4週の時点で炭酸ガス群で有意に高い骨癒合率を認めた。組織学的な骨折治癒過程進行度を表すAllen’s grading scoreは、評価した全てのtime pointで炭酸ガス群において有意に高く、骨折治癒過程が進行していた。骨強度評価では評価項目全てにおいて炭酸ガス群で有意に高い数値を示した。以上の結果から、糖尿病という骨折治癒に不利な状況下でも炭酸ガス経皮吸収が骨折治癒を促進することが証明された。 現在、炭酸ガスの詳細な作用機序の解明のため、順次real time PCRを行っている段階である。競争的資金
