Abstract
A modular femoral hip joint prosthesis can include a proximal femoral body having a distal end and a proximal end. The proximal end can be adapted to mate with a femoral head. A femoral stem can have a proximal section and a distal section. The femoral stem can be adapted to matingly connect with the distal end of the proximal femoral body. The proximal section can have a porous metal coating that is adapted to facilitate bony ingrowth. The distal section can have at least one spline formed along an outer surface.

A modular femoral hip joint prosthesis comprising:
- a proximal femoral body having a distal end and a proximal end, the proximal end being adapted to mate with a femoral head;
- and
- a femoral stem having a proximal section and a distal section, the femoral stem being adapted to matingly connect with the distal end of the proximal femoral body, the proximal section having a porous metal coating adapted to facilitate boney ingrowth, the distal section having at least one spline formed along an outer surface.
A modular femoral hip joint prosthesis comprising:
- a one-piece femoral stem having a proximal section and a distal section, the proximal section adapted to matingly connect with a proximal femoral body and having a porous metal coating that covers substantially all of the proximal section and is adapted to facilitate boney ingrowth, the distal section having a plurality of longitudinally extending splines formed along an outer surface, wherein the distal section tapers toward a distal tip.
