A prosthesis in the form of a cage having opposed complimentary bearing surface assemblies. The bearing surface assemblies moveable towards and away from each other. The moving mechanism being part of the bearing surface assemblies. Each of the bearing surface assemblies having an outer bearing surface whereby movement of one bearing surface assembly in one direction will move the bearing surface assemblies away from each other and movement in the opposite direction will move the bearing surface assemblies towards each other.

1. A prosthesis comprising:(a) at least one set of opposed complimentary bearing surface assemblies, each of said bearing surface assemblies comprises top and bottom sections, each section having an outer bearing surface with an inner face and a wall extending therefrom, said wall comprising a plurality of inclined cam surface extending substantially vertically from the inner face of said bearing surface and away therefrom; (b) means for moving said bearing surface assemblies towards and away from each other, said moving means being integral of the bearing surface assemblies, whereby movement by the moving means in one direction will move the bearing surface assemblies away from each other and movement by moving means in the opposition direction will move the bearing surface assemblies towards each other, thereby increasing and decreasing, respectively, the height of said prosthesis; and (c) partition means extending substantially vertically and away from the inner face of said bearing surface of each section comprises a pair of outer partitions and an inner partition, wherein said outer partitions of said top section engage said inner partition of said bottom section and said outer partitions of said bottom section engage said inner partition of said top section to allow movement of said top section relative to said bottom section.
