摘要:
A hip resurfacing femoral prosthesis has a partial ball component (20) having an outer surface (22) shaped to conform to an acetabular socket and has a mating sleeve component (10) with an internal bore (14) adapted to receive a femoral head (7). The head (7) has been shaped (71) and dimensioned to engage the bore (14) and is retained by bone ingrowth, an interference fit or by bone cement. The ball component (20) and sleeve (10) axes (E,F) may be offset to reposition the outer surface (22).
