Abstract
A femoral component (10) for a hip prosthesis. The femoral component (10) comprises a femoral stem (18) including a proximal stem portion (24) for being implanted in the proximal portion of a femur and a distal stem portion (28) for being closely received in the medullary canal of the femur. The distal stem portion (28) is releasably secured to the lower end (32) of the proximal stem portion (24) such that the proximal and distal stem portions (24 and 28) can be independently sized to accommodate a specific femur configuration. The femoral component (10) further comprises a neck portion (20) and a head portion (22), the head portion (22) being releasably secured to the outboard end (52) of the neck portion (20). In the preferred embodiment, the proximal stem portion is held in place in the proximal femur through the use of a porous surface portion (42) which receives bone ingrowth from the femur.
