Title: Hip joint prosthesis

Abstract: A prosthesis for replacement of a damaged joint or load-bearing structure in an animal or human body comprises a shaped structural member, a relatively thick or cushioning coating of a physiologically inert elastomer over the surfaces of the structural member in load-bearing relationship with the skeletal structure of the body, and an open-pore, tissue-ingrowth-receptive fabric coating the elastomer, all elements being firmly bonded to each other. In many embodiments, a stem of the prosthesis comprising the above elements is adapted to be inserted into a bone cavity, and is eventually affixed firmly thereto by fibrous tissue and bony ingrowth. Stability of the stem portion is enhanced by buttresses integral with the base of the stem.
