摘要： Bipolar prostheses which include various structures and other techniques for optimizing material wear and mechanical strength properties. Such prostheses feature, for example, improved resistance to polyethylene wear while also reducing potential for dislocation of the femoral stem from the prosthesis. Such techniques and structures include varying wear resistance and mechanical strength treatment in various components of the prostheses or portions of those components as desired to improve, accentuate or optimize wear performance and dislocation reduction, locking ring structural features, structures for retaining locking rings in the bipolar prosthesis shell, and structures for limiting or reducing movement or rotation of locking rings and liners in bipolar prosthesis shells.
