<p>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. </p> |
