ABSTRACT OF THE DISCLOSURE A method and apparatus for affixing a prosthesis to bone is provided wherein stresses are transferred from the prosthesis to hard bone in a manner which corresponds to the stress transfers which occur in natural bone. The apparatus comprises a body having an outer surface at least a portion of which is contoured to mate with a portion of the inner surface of the hard bone to which the prosthesis is being affixed so that, in the region of said mating portions, a substantial fraction of the hard bone is in close proximity to or in contact with the outer surface of the body, said outer surface in said mating region being textured to increase the frictional engagement of the surface with the hard bone. In certain preferred embodiments of the invention, a prosthesis made from a titanium-containing material and having high overall strength and flexibility is provided which includes a portion having a coating of porous metal into which bone can grow.
