The purpose of our research program is the reconstruction of musculoskeletal disorders in orthopaedic surgery. The loss of locomotor function reduces the patient’s quality of life. if it takes time to reconstruct the function, there is a risk of disuse syndrome and complications of other organ diseases. Rapid functional reconstruction using artificial joint, metal implant, and artificial bone is desired for such patients. We are developing patient-specific and disease-specific medical device for next-generation surgery.
Research and Education
We are developing original artificial hip joint implant, 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. The artificial knee joint aims to improve long-term durability and patient satisfaction by analyzing the knee joint kinematics using computer simulations.
Spinal fusion cage:
We have developed a spinal fusion cage using bioactive porous titanium porous and are applying it clinically.
We are developing artificial bones that have a high affinity with living bone. By applying special treatment to the surface of titanium metal and polymer, we are developing new artificial bones and artificial joints that have functions such as bone formation and antibacterial properties. And additive manufacturing technology is introduced to realize the patient-specific and disease-specific devices.
