Abstract

The magnitude and direction of the resultant hip joint force are generally different in different body positions. Therefore the stress distribution in the hip joint is also affected. The aim of this work is to calculate the stress distribution in the hip joint articular surface for various directions and magnitudes of the resultant hip joint force. For this purpose a simple three-dimensional mathematical model of the hip joint is developed. The articular stress integrated over the weight bearing area yields the resultant hip joint force. The value of stress at the pole and coordinates of the p
