Abstract

An implant removal tool used to remove a femoral implant from a femur bone by providing a substantially U-shaped body having a substantially rectangular-shaped opening located thereon that allows the substantially U-shaped body to be placed over a neck of a femoral implant so a sharpened front edge of the substantially U-shaped body makes direct contact with an inner surface of the stem of the femoral implant. The U-shaped body may have front side edges that extend beyond a front edge to allow the front side edges to cut anterior and posterior surface of the implant.

Claims (18)

1 . An implant removal tool, comprising:

a substantially U-shaped body including two side walls; and

an opening in a curved portion of the substantially U-shaped body,

wherein the opening forms a through-hole in the curved portion and is shaped to accommodate at least a portion of a femoral implant to pass therethrough,

wherein the opening has a curved opening front edge,

wherein the two side walls each have a side front edge that is connected to the front edge,

wherein each of the side front edges has a triangular-shaped point extending beyond the front edge away from the opening.

2 . The implant removal tool of claim 1 , wherein the substantially U-shaped body has a front edge configured for cutting.

3 . The implant removal tool of claim 2 , wherein the front edge of the substantially U-shaped body is sharpened.

4 . The implant removal tool of claim 1 , wherein the curved opening front edge is curved to conform to a femoral implant.

5 . The implant removal tool of claim 1 , wherein the opening has an opening right side edge and an opening left side edge.

6 . The implant removal tool of claim 5 , wherein the opening right side edge and the opening left side edge have a length equal to a height of an upper portion of the femoral implant.

7 . The implant removal tool of claim 1 , wherein the opening has a width substantially equal to a distance between the two side walls.

8 . The implant removal tool of claim 1 , further comprising:

a portion extending from a rear surface of the substantially U-shaped body, the portion being configured to attach a handle.

9 . The implant removal tool of claim 1 , further comprising:

a handle integrated into the substantially U-shaped body.

10 . The implant removal tool of claim 1 , wherein each of the side front edges are sharpened.
