    摘要： Implants are made of materials having asymmetric modulus gradients. For example, an implant, such as a hip implant, is made of a material having a stiffness gradient between a proximal portion near a hip joint and a distal portion extending downward into the marrow of the femur. Among other benefits, the asymmetric modulus gradient mitigates problems associated with stress shielding and does not excessively wear or deteriorate the proximal portion of the implant.

    摘要翻译： 植入物由具有不对称模量梯度的材料制成。 例如，诸如髋关节植入物的植入物由在髋关节附近的近端部分和向下延伸到股骨髓的远侧部分之间具有刚度梯度的材料制成。 除了其它益处之外，不对称模量梯度减轻了与应力屏蔽相关的问题，并且不会使植入物的近端部分过度磨损或劣化。
