Abstract
A femoral insert combines bone ingrowth surfaces in the proximal portion of the shaft which is wide in the medial-lateral direction and curved in the medial aspect with a distal portion which has a round cross-section and is curved in the direction of the anterior bow of the femur. Accordingly, firm fixation of the implant is initially provided by the distal portion functioning as an intramedullary rod while long term stabilization is achieved proximally through bone ingrowth. Also, the neck connecting the spherical head to the shaft through the collar is anteverted with respect to the collar at an angle of about 10.degree. to 12.degree.. The prosthesis for the left femur is basically a mirror image of the prosthesis for the right femur.
