ABSTRACT:
A machining assembly, including a novel broach design, are disclosed for preparing a femoral medullary cavity for receipt of a femoral prosthetic stem, wherein the configuration of the implantation site allows for the neutral alignment of the prothesis within the medullary cavity for improved rigid fixation of the prosthetic stem therein. Aspects of the inventive machining assembly include a novel broach comprising a proximal lateral recess that allows for initial avoidance of the greater trochanter during implantation, thereby resulting in the preparation of a neutrally aligned cavity with respect to the broach. The machining assembly also includes a means for subsequently removing the bone of the greater trochanter once neutral alignment between the medullary cavity and broach are achieved for the subsequent implantation of a neutrally aligned femoral prosthesis.
