Abstract:
Objective To address the medical problems, in treatment of avascular necrosis of the femoral head, on loosening and subsidence of the prosthesis of femoral head. A set of Mushroom Shaped Surface Prosthesis of Femoral Head was designed. Methods Based on biomechanical of the femoral head and the principle of transferring the force through femoral head while reducing stress-sheltered, nickel-titanium alloy and other new medical alloy materials were used to develop a prosthesis, which not only can be a weight-bearing device, but also promotes bone-growth. Results The prosthesis is novel, compact and little-volume, and the manipulation of surgery is convenient and secure. Conclusion The design of this prosthesis can provide new ways or ideas for designing the femoral head replacement prosthesis to solve problems on loosening and subsidence.
