Orthopaedic Surgery, Division of Reconstruction for Musculoskeletal Disorders

shfuji Shunsuke Fujibayashi, MD, PhD. Program-Specific Professor

The purpose of our research program is the reconstruction of musculoskeletal disorders in orthopaedic surgery. The loss of musculoskeletal function decreases the QOL of the patients. Especially in elderly patients, it related to disuse syndrome and dysfunction of other organs. Rapid reconstruction using artificial joint, metal implant, and artificial bone is required in such cases. We are developing patient-specific and disease-specific medical device for next-generation surgery.

Research and Education

Artificial joint: We have developed original implants for total hip arthroplasty (THA), which have superior mechanical properties and biocompatibility. Currently we are developing bioactive bone cements for arthroplasties, as well as bioabsorbable screws for the reconstructive surgeries. Knee kinematics and mechanical properties have been analyzed for long-term durability using computer simulation for total knee arthroplasty (TKA).
Biomaterials: Our research interests of biomaterials are the development of artificial bone and artificial joint using titanium metal and polymers by surface bio-chemical treatment. And additive manufacturing technology is introduced to realize the patient-specific and disease specific device.
