用于关节替代物的金属轴承
摘要：
本发明涉及用于关节替代物的金属轴承。本发明提供了一种矫形关节假体，该矫形关节假体包括具有软金属轴承表面的第一组件和具有硬金属轴承表面的第二组件。所述软金属轴承表面具有至少大约20Rc的硬度，而所述硬金属轴承表面具有比所述软金属轴承表面高至少大约15Rc的硬度。所述软金属轴承表面和所述硬金属轴承表面构成为彼此关节连接。所述硬金属轴承表面相对于所述软金属轴承表面的硬度比优选为至少大约1.5，并且优选为小于大约3。所述硬金属轴承表面优选地比所述软金属轴承表面硬出不超过大约40Rc。所述硬金属轴承表面优选地具有大约40Rc与大约60Rc之间的硬度。
摘要（英）：

An orthopedic joint prosthesis comprising a first component having a soft metal bearing surface and a second component having a hard metal bearing surface. The soft metal bearing surface has a hardness of at least about 20 Rc, while the hard metal bearing surface having a hardness greater than the soft metal bearing surface by at least about 15 Rc. The soft and the hard metal bearing surfaces are configured to articulate with one another. The differential hardness of the hard metal bearing surface to the soft metal bearing surface is preferably at least about 1.5, and is preferably less than about 3. The hard metal bearing surface is preferably not more than about 40 Rc harder than the soft metal bearing surface. The hard metal bearing surface preferably has a hardness of between about 40 Rc and about 60 Rc.
