THE PEAK STRESS, WEIGH BEARED AREA AND STRESS DISTRIBUTIONS AT HUMAN HIP JOINT

Abstract

The peak stress, the weight beared area and the stress distributions of the articular contact at the human hip joint are the most important factors, which determine the location of the degenerative foci that later result in degenerative damage and in the development of osteoarthritis. In this paper, firstly a generalization analytical modelling for evaluating the peak stress, the weight beared area and the stress distributions of the articular contact at the human hip joint is developed; secondly, as an example, the numerical results for evaluating the peak stress, the weight beared area and the stress distributions of the articular contact at the human hip joint are presented. The results show that the numerical values from the present modelling are good agreement with the literatures.
