Design and optimization of a hip disarticulation prosthesis using the remote center of motion mechanism.
Background: Hip disarticulation prostheses (HDPs) are not routinely seen in clinical practice, and traditional hip prostheses rotate around an axis at the front side of the pelvic socket.Objective: This study proposes a mechanism to restore the rotation center to the acetabulum of the amputated side...

Optimization was achieved by a genetic algorithm with the maximal integral size and minimal driving force of the mechanism.Results: The prototype was developed by final optimal results and tested by a hip disarticulated amputee. Testing results revealed that the RCM-HDP improved the range of motion of the hip prosthesis by 78%. The maximal flexion of the assorted prosthetic knee was closer to the sound side than a traditional HDP by 15%.Conclusion: The proposed RCM-HDP promoted the kinematic performance and symmetry of the hip prosthesis compared to the traditional design. pubtype: Academic Journal doctype: research Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
