Outline of Final Research Achievements

This study was aimed to develop an instrumented prosthesis to measure joint reaction forces during total hip arthroplasty surgery. In this study, measurements of existing prostheses, design, manufacturing and measurements were scheduled. As results, we have developed measuring sensor that is ready to use. Moreover, a musculoskeletal computer model was developed to validate the measurements.

Academic Significance and Societal Importance of the Research Achievements

本研究で目指す、人工股関節手術中に関節反力を測定が可能となれば、人工股関節の手術後の脱臼をはじめとする問題が減少し、その結果患者に対して負担となりうる再置換手術件数の減少も予想される。人工股関節の初回埋め込み件数自体は今後増加することは避けられないが、再置換手術の件数減少は可能と考えている。それは、患者への負担軽減のみならず、我が国の医療費の軽減にもつながり、今後の高齢化社会において目指すべき方向だと考えられる。
