Abstract

A surgical cutting guide is described which can guide a cutting implement to cut in a pair of planes at a defined relative orientation. The cutting guide comprises a first plate defining a first cutting plane, a second plate defining a second cutting plane at an angle to the first cutting plane; and a base member to which both the first plate and the second plate are attached. The first and second cutting planes intersect each other at a line of intersection and both the first plate and the second plate extend beyond the line of intersection.

Claims

1. A surgical cutting guide for use in cutting part of a bone, the surgical cutting guide comprising:

a first plate defining a first cutting plane, the first plate having spaced edges defining a first opening;

a second plate defining a second cutting plane at an angle to the first cutting plane, the second plate having spaced edges defining a second opening; and

a base member attached to the first plate and the second plate and having a pair of pins extending outwardly from the base member for mounting the surgical cutting guide on the bone;

wherein the first and second cutting planes intersect one other at a line of intersection and portions of both the first plate and the second plate extend beyond the line of intersection on both sides of the line of intersection, and wherein the first and second plates comprise metal and the base member comprises a different material

wherein the first opening is aligned with the second opening along the line of intersection; and

wherein at least one of the first opening and the second opening are enclosed within the first plate and the second plate, respectively.

2. A surgical cutting guide for use in cutting part of a bone, the surgical cutting guide comprising:

a first plate defining a first cutting plane, the first plate having spaced edges defining a first opening;

a second plate defining a second cutting plane at an angle to the first cutting plane, the second plate having spaced edges defining a second opening; and

a base member attached to the first plate and the second plate and having a pair of pins extending outwardly from the base member for mounting the surgical cutting guide on the bone;

wherein the first and second cutting planes intersect one other at a line of intersection and portions of both the first plate and the second plate extend beyond the line of intersection on both sides of the line of intersection, and wherein the first and second plates comprise metal and the base member comprises a different material; and

wherein the base member comprises a first substantially planar surface, to which the first plate is attached and a second substantially planar surface to which the second plate is attached, and wherein the first substantially planar surface and the second substantially planar surface meet at an edge parallel to the line of intersection.
