Abstract

The adaptive bone remodeling phenomenon in the femur before and after prosthetic total hip joint replacement (THR) was investigated using the three dimensional finite element method. A normal hip joint model which composed of the proximal femur and the pelvic bone including femoral head and acetabular was constructed three-dimensionally by our method reported previously. The simulation model was use to determine the bone density distribution in a normal femur using the adaptive bone remodeling theory proposed by Weinans et al. It was confirmed that the bone density distribution obtained from the simulation was almost similar to the physiological distribution of mineral content of a normal human femur observed by an X-ray photograph. Subsequently, THR model was constructed by the insertion of a noncemented pro
