Abstract
In order to obtain the optimal model of femoral head prosthesis, a novel modeling method is proposed in this paper. It can revert the necrotic femoral head into the satisfactory model that primely matched with the acetabulum. This new method not only affords a theoretical model for the accurate operation position fixing in orthopaedic clinic, but also provides an innovative practical means for the individualized manufacturing of artificial femoral head prosthesis. Two male sufferers with different femoral head necrosis extent were chosen as the experimental subject for the prosthetic modeling simulation. The prosthetic models highly presented the primary shape of the femoral heads.
