Orthopedic Surgery

Research Summary

Orthopedic surgery is used to treat musculoskeletal disorders, including those of the bone, cartilage, joint, ligament, tendon, and nerve. Therefore, our department has conducted various clinical and basic studies on orthopedic surgery. Among the studies, one of the most important is about the “Detection of bacteria in the bone and joint infection using the next-generation sequencer.” Implant infection is the one of the most serious complications of joint replacement and spinal fixation. The conventional cultivation method sometimes cannot detect, or takes a long time to detect, the causative bacteria. The next-generation sequencer method can detect the causative bacteria at the genetic level. Therefore, it can be used when the conventional cultivation method fails to detect the causative bacteria and to detect them faster. The development of a technique for this method is highly important and may contribute to future medical treatments.
The other clinical studies include the following: “An evaluation of gait pattern of patients after total knee replacement using 3-D kinematic analysis device,” “Analyses of fragile bones at the spinal fixation,” and “Analyses of the EMG during a spine surgery.” The basic studies include “Regenerative organization using bone marrow cells” and “Treatment of autoimmune diseases using bone marrow cells.”
