This paper describes a newly developed hip disarticulation prosthesis of which a rotational center of a hip joint was made closer to an anatomical position. The new hip joint was proposed and designed, and a prototype of the hip joint was fabricated. The hip joint was integrated with a socket of a hip disarticulation prosthesis, and a new hip disarticulation prosthesis (nHDP) was made. Choosing an appropriate knee joint and foot for the nHDP through the trial and error, a hip amputee could walk using the nHDP. In order to evaluate the nHDP, analyses of walking motion were performed for one subject. The result showed gait using nHDP had less unsymmetrical motion of lower limb compared with gait using a existing hip disarticulation prosthesis which was used by the subject in his daily life. It was shown that the nHDP was effective for changing gait of hip disarticulation amputee better.
