    摘要: A metallic implantable finger joint has a biocompatible protective coating and includes both a base member and a protraction member. The base member is formed with a recess and has a protrusion projecting from inside the recess. The protraction member has a hemispherical surface which is slidingly engageable with the recess of the base member. Additionally, the protraction member is formed with a groove which engagingly receives the protrusion from the base member. This engagement is such that when the base member is juxtaposed with the protraction member, the interaction between the protrusion and the groove allows for relative movement between the members in flexion-extension, lateral rotation and pure rotation. The finger joint can also include implant barbs which are selectively engageable with the base member and the protraction member.

    摘要: A ceramic prosthesis for the living body wherein a plurality of globular or indefinite-shaped ceramic particles are bonded by sintering into one body directly or indirectly with the surface of a ceramic substrate of alumina ceramics, ziroconia ceramics or the like to permit the ingrowth of bone cells into gaps between the particles of the ceramic particles. The material is very suitable for a prosthesis such as an artifical joint in that the material is enabled to provide stront bonding and fixing thereof to the living bone by permitting early ingrowth of bone cells in the living body and to provide stability of the bonding and fixing over a long period of time.
