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 pole are determined by solving this vector equation. it is shown that inclination of the resultant hip joint force with respect to the frontal plane of the body increases the maximal value of stress in the articular surface.
