ABSTRACT:
A bone implant prosthesis having an outer stress-free surface and a subsurface carried generally beneath and parallel to the outer surface for bearing tensile stresses. The prosthesis of the invention includes a plurality of slots undercutting the outer surface of the prosthesis thus forming a stress bearing subsurface to free the outer surface from being subjected to substantial stresses. The stress-free outer surface is readily adaptable to receive a porous coating to enhance bone ingrowth without decreasing the stress resistance characteristics of the prosthesis.
