Abstract
An improved femoral component for use in a total hip replacement prosthesis comprises a stem portion and a combined head and neck portion. The stem portion includes a proximal portion and a distal portion which are angularly related with respect to one another and with the proximal portion including a recess formed therein for receipt of the tapered portion of the head and neck component. The head and neck component includes a substantially part spherical head portion attached to a neck portion and a tapered portion angularly attached to the neck portion via a basalar neck portion with the tapered portion being adapted to be permanently inserted into the recess portion of the proximal end of the above described stem portion. The stem portion includes a plurality of recesses on the periphery and longitudinal extent thereof which recesses receive fiber metal pads which are provided to allow bony ingrowth therein to retain the femoral component permanently installed in the proximal end of the femur.
