    Abstract: A procedure for contouring the wall of a femoral cavity in a femur for the reception of a femoral stem to be seated within the femoral cavity employs a femoral broach which includes cutting teeth aligned along peripherally spaced apart longitudinal rows extending along a portion of the outer surface of the blade of the broach for forming a multiplicity of alternating longitudinally extending generally parallel grooves and ribs in the wall of the cavity, at least some of the grooves being contiguous with harder portions of the bone of the femur while the ribs are comprised of softer portions of the bone so that completion of the contouring will be signalled by bottoming of the blade of the broach upon the harder portions of the bone and upon implant, the femoral stem will be seated upon the harder portions of bone while the softer portions of bone will be compressed between the femoral stem and the harder portions of bone to accomplish fixation by an interference fit. Upon completion of the contouring of the wall of the cavity, and prior to withdrawal of the blade of the femoral broach, the seated blade of the broach serves as a true gauge of the subsequent location of the femoral stem relative to the femur. A vented, interchangeable distal tip on the blade of the broach pilots the broach for precise alignment of the blade during the contouring procedure.

    Abstract: An acetabular cup prosthetic device comprised of an outer shell component and a inner bearing insert and the method of implanting the acetabular cup prosthetic within a patient. The outer surface of the shell component for the present invention acetabular cup has a plurality of regions which conform to the curvature of at least one ellipsoid. To implant the shell component, the acetabulum of a patient is spherically reamed to a size slightly smaller than that of the outer surface of the shell component. As the shell component is inserted into the spherically shaped acetabulum, the interior surface of the acetabular cavity deforms to assume a substantially ellipsoidal curvature, producing an interference fit between the rim region of the shell component and the upper peripheral rim region of the acetabulum. The remaining surface regions of the acetabulum conform substantially to the ellipsoidal shape or shapes defined by the remaining surface regions of the shell component so that surface contact is established without the development of ejection forces therebetween.

    Abstract: A prosthetic implant device for use in replacing the ball end of a biological joint, the replacement including a spherical head for insertion into a natural socket, an insert in the head, a ball-shaped member captured in the insert and having a neck and a stem for mounting the ball-shaped member on the end of the biological member on which the ball is being replaced, and a radially-expansible ring for capturing the ball-shaped member within the insert the ring having a downwardly and inwardly sloping outer wall and seated in a recess in the insert, the recess having upper and lower end walls for defining upper and lower limits of axial movement of the ring within the recess to permit selective removal of the ball-shaped member from the insert and to prevent inadvertent disengagement of the ball-shaped member from the insert.
