Abstract: An acetabular cup has a shell having a recess therein, the recess is open to an outer surface of the shell. The recess has an enlarged portion spaced from the shell outer surface with a diameter greater than the diameter of the opening at the surface. An insert is provided for insertion into the recess in the shell outer surface. The insert has a height greater than a depth of the recess and has a solid portion and a bifurcated portion having at least two side openings forming two to four sectors. A base of the sectors formed by bifurcated portion has an outwardly extending flange for insertion into the enlarged portion of the recess.

Abstract: An acetabular rim cutter has an annular cutting face provided on a rotatable carrier. A coupler is provided for attaching the carrier to a rotational power source. A guide element is axially aligned with the cutting face to locate and align the cutting face on the acetabulum with which it is to be used. Preferably, the guide element is axially movable in relation to the cutting face and a resilient element is provided for biasing it axially away therefrom.

Abstract: A kit and a method for implanting a prosthetic acetabular cup in an acetabular has a prosthetic acetabular cup having an open end for receiving a head of a prosthetic femoral component. The cup has a flange extending outwardly from a surface thereof adjacent the open end. The flange is angled toward the acetabulum. The acetabulum is prepared to receive the prosthetic acetabular cup, the preparation includes forming a circumferential rim shaped seat in the bone around the acetabulum. The cup flange has a maximum diameter less than the outer diameter of the circumferential rim.

Abstract: A targeting apparatus for use in performing endofemoral osteotomy surgery has a support element provided with a drill guide. The apparatus has a connector for securing a support element to the proximal end of a prosthesis to be implanted. The apparatus includes a proximal location element which is shaped to extend around the great trochanter and muscle of the femur in which the implant is to be located. An adjustor is provided for adjusting the angular position of the drill guide in relation to the femur about a proximal-distal axis.

Abstract: A targeting apparatus for use in performing transfemoral osteotomy surgery includes a support element provided with a drill guide. A device is provided for securing the support element to a prosthesis to be implanted, and to a resectioned femur. An adjusting device for adjusting the angular position of the drill guide in relation to the resectioned femur about a proximal-distal axis is also included.

Abstract: A targeting apparatus for use in resectioning a femur when performing transfemoral osteotomy surgery has a drill guide element which includes a line of drill openings each of which is adapted to guide a drill for drilling holes in the femur. A connector is provided for securing the drill guide element to a femur to be resectioned with the line of openings extending in a proximal/distal direction along the femur.
