    • Endoprosthetic bone joint devices commonly comprise one or more components having one part adapted for securement with a bone of the joint and another part adapted for mutual articulatory engagement with another such component or natural integer of the joint. This invention provides such a component which is substantially wholly porous, but in varying manner with greater porosity in the one part than the other part. This variation preferably involves pore diameters in the one and other parts within respective ranges from 10 to 250 (Alpha) and substantially zero to 150 (Alpha). Also, the component is preferably made of fibre reinforced material with the reinforcement conforming to a predetermined pattern, a suitable material being carbon - fibre - reinforced carbon.
    • 人造内骨关节装置通常包括一个或多个部件,所述一个或多个部件具有适于与关节的骨固定的一个部分和适于与关节的另一个这样的部件或自然整数相互关节接合的另一部分。 本发明提供了基本上完全多孔的部件,但是以不同的方式在一部分中具有比另一部分更大的孔隙率。 该变化优选包括在10至250(α)和基本上0至150(α)范围内的一个和其他部分中的孔径。 而且,部件优选地由纤维增强材料制成,其中增强件符合预定图案,合适的材料是碳纤维增强碳。
