ABSTRACT:
A method and apparatus for performing hip surgery utilizes a preformed sleeve formed of bone cement material and having apertures which is positioned in the femoral cavity. Fresh bone cement is injected under pressure to fill the femoral cavity including the apertures and any spaces or voids between the preformed sleeve and the wall of the cavity. A femoral prosthesis having a stem portion is implanted therein. The interior wall of the sleeve is larger than the stem exterior wall portion encircled by the sleeve such that fresh bone cement is between the interior wall of the sleeve and the stem.
