Femoral resurfacing implantation is alternative option to total hip replacement for the surgery of femoral head osteonecrosis. Although it was developed first in the 1970s, it did not come into wide use because postoperative stability was not sufficient for a long period. Femoral resurfacing implantation has been attracted the attention of orthopedic surgeon again, since material and design technology has been recently progressed In this study, finite-element models of femoral head replacement with the resurfacing implantation were created based on clinical CT images, and stress analyses were carried out considering inhomogeneous property of bone. Furthermore, influence of stress distribution around the femoral head with arrangement of the resurfacing implant was investigated by changing position of the implantation.
