Abstract

Dislocation and wear of an artificial hip joint are still serious problems to be solved for THA. Specifically, the mechanism of dislocation of an artificial hip joint has not been clarified. The hip joint simulator has been developed to analyze the phenomenon of dislocation of an artificial hip joint. In the simulator, the muscle model is applied in addition to the floor reaction force in order to calculate the hip joint contact force vector. However, since individual differences in the locations of the muscle insertions exist, the resultant force vector which is generated by the muscles around the hip joint is different between individuals even though the motion is almost the same. In this paper, the influence of the personal difference of the location of muscle insertions on dislocation of an artificial hip joint is investigated.
