ABSTRACT:
An acetabular cup includes a plurality of bone receiving depressions on its convex exterior surface. Bone, obtained from the femoral head of the hip to be replaced, is morselized and then compressed in the bone receiving depressions. The dense bone on the exterior surface of the acetabular cup serves as a graft and acts as a new subchondral bone. The bony fixation technique may be used on other prosthesis (e.g., shoulders, and the like). Variations in size, shape, depth and distribution of the recesses can be modified to make this form of fixation applicable to all forms of bone/prosthesis fixation.
