ABSTRACT
By integrating bone-remodeling theory with finite element (FEM) models, the behavior of femoral remodeling after implantation of artificial femoral head was simulated and the stress shield effect of artificial femoral head on the femur was analyzed quantitatively. Bone was calculated with finite element code of the FEM model. The normal loading condition of femur was used as Model One, and the stress condition that bone was fixed by the bone-cement of the artificial head with collar was used as Model Two. It has been shown that bone was stress-shielded by the artificial femoral head and femur resorbed. Bone resorption near the proximal artificial stem was very severe. Its cross-section resorbed the greatest. The ratio of cross-sectional resorption was psi = 31.3% and the ratio of loss of the anti-bend cross-sectional modulus was zeta = 54.58%.
