Prosthetic modeling of the femoral head based on mesh segmentation

For the sake of getting the optimal femoral head prosthesis model, a novel modeling method is proposed. It can reconstruct the shape of the subsided femoral head owing to ischemic necrosis. In this paper, two male sufferers with different necrosis extent were chosen as the experimental subject for contrastive simulation. The prosthetic models highly presented the primary shape of the femoral heads. The results proved that the fitted models primely matched with the acetabulum.
