A semi-automatic procedure to generate a three-dimensional finite element mesh of a cadaver femur from computerized tomography (CT) slices was studied using GE 9800 CT scanner. Femoral stem prostheses were simulated to implant into the femur through a computer aided design (CAD) system and the pseudo CT slices were generated producing a three-dimensional mesh of this system. The biomechanical response of the system were investigated by finite element analysis. Due to the versatility of finite element technique, a powerful tool for the analysis of bone/endoprosthesis systems was established. The study also provided a way to investigate the biomechanical influences of surgical positioning inaccuracy of an implanted system seldom studied in this field.
