Biomechanical analysis of a hip joint with resurface type prosthesis was performed to characterize the stress conditions on the surfaces and interiors of the bones. Three different types of cementing were considered in the analysis in order to assess the effects of cementing on the stress state in the femoral head. The finite element analysis clearly exhibited the existence of stress shielding due to the difference of elastic modulus between the hard head component and the softer bone tissue. It was also found that the cementing affects the stress states in the femoral head and a partial cementing with gap region tends to increase the stress level.
