A stress analysis using a three dimensional finite element method was made in order to enhance the understanding of characteristics of the stress distribution in artificial hip joint systems. A simplified axisymmetric model was employed to get an insight into effects of several design aspects on the stress distribution in the system. The analysis included considerations of variations in elastic constants of the bone cement and of the prosthesis. Some guidelines for an advanced design which will minimize the risk of loosening of the femoral component were suggested.
