A femoral component for a hip prosthesis includes a proximal end shaped in an anatomic manner to form asymmetrical sides. In particular, a lateral side forms an acute angle with an anterior side and a medial side forms an arcuate surface.

A femoral component for a hip prosthesis having a distal end adapted for disposition within an intramedullary canal of the femur and a proximal end extending outwardly of the intramedullary canal for disposition adjacent an acetabulum, the femoral component defining a straight longitudinal axis and a proximal portion which substantially matches the contour of the intramedullary canal for a tight fit therein, the proximal portion including a porous surface to enhance fixation of the femoral component within the intramedullary canal, and the proximal portion further including substantially planar anterior, posterior, and lateral sides and a medial side a lateral side and a medial side, a cross section of the proximal portion forming substantially linear edges for the anterior, lateral and posterior sides while the cross section forms a substantially arcuate surface for the medial side to generate a predetermined asymmetric contour substantially matching a contour of the intramedullary canal of the femur, and the linear edge of the lateral side cooperates with the linear edge of the posterior side to form a slightly obtuse angle therebetween.
