Research Contents
The fieldof orthopaedics covers the treatment of a wide range of patients of all ages with various joint disorders, including disorders of the hip, knee, foot, shoulder, and elbow, spinal disease, hand and peripheral nerve injuries, rheumatoid arthritis; osteoporosis, bone and soft-tissue tumors, fractures; and sports injuries. We engage in both basic and clinical research aiming to elucidate pathological conditions and to develop new methods of diagnosis and treatment for these disorders. Our research is funded not only publicly, by Grants-in-Aid for Scientific Research from the Ministry of Health, Labour and Welfare and by research funds from the Ministry of Education, Culture, Sports, Science and Education, but also privately, through the acquisition of various competitive funding sources. One of the representative research topics of our department is the piezoelectricity of bone, the elucidation of which was an outstanding achievement now engraved into the history of Japanese Orthopaedic Association. Another of our research theme is idiopathic osteonecrosis of the femoral head (ION): our department is a global leader for the prevention of steroid-induced ION (development of preventive method such as gene analysis and electromagnetic field stimulation, so on). Basic research is also being conducted in several other areas, including development of the new treatment method for osteoarthritis targeting HIF-1 alpha, comprehensive study concerning fracture healing and circadian rhythm, investigation of the reaction mechanism of chondroblasts under stress of physiological hypoxic environment, treatment of joint disorders using small interfering RNA, the promotion of regeneration of peripheral nerves and skeletal muscle, intervertebral disc regeneration using platelet-rich plasma and biodegradable gelatin hydrogel microspheres, and the anticancer or antimetastatic effect of bisphosphonate and sulforaphane, which target cancer-related genes and may help treat malignant bone and soft-tissue tumors. We are also conducting clinical research in several areas, namely, radial imaging as a method of evaluating the condition of the acetabular labrum in hip dysplasia, minimally invasive microscopic or microendoscopic muscle-preserving interlaminar decompression for lumbar spinal canal stenosis, 10 year epidemiological study of deformity in the rheumatoid hand, visualization of pain in lumber spinal canal stenosis using functional MRI of the brain, establishment of a new image analysis method for foot and ankle deformity. Through these studies, we aim to realize original research with a global impact.
