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 comprising:

a first plate defining a first cutting plane;

a second plate defining a second cutting plane at an angle to the first cutting plane;

a base member attached to the first plate and the second plate; and

wherein the first and second cutting planes intersect one other at a line of intersection and both the first plate and the second plate extend beyond the line of intersection.

2. The surgical cutting guide of claim 1, wherein the first plate and the second plate are interlocked or engaged with each other along the line of intersection.

3. The surgical cutting guide of claim 1, wherein the first plate defines a first opening and the second plate defines a second opening, at least a portion of the first plate extends through the second opening, and the first opening is aligned with the second opening along the line of intersection.

4. The surgical cutting guide of claim 3, wherein the first opening has at least one substantially straight edge that is parallel to the line of intersection and spaced from the second cutting plane.

5. The surgical cutting guide of claim 3, wherein the second opening has at least one substantially straight edge that is parallel to the line of intersection and spaced from the first cutting plane.

6. The surgical cutting guide of claim 3, wherein the first opening and the second opening are enclosed within the first plate and the second plate, respectively.

7. The surgical cutting guide of claim 3, wherein the first plate and the second plate each have at least one side, the first opening extends to a side of the first plate, the second opening extends to a side of the second plate, and at least a portion of the second plate extends through the first opening.

8. The surgical cutting guide of claim 1, wherein the first plate and second plate each have substantially the same shape as each other.

9. The surgical cutting guide of claim 1, wherein at least one of the first plate and the second plate has an edge portion defining a shape for indicating the position of the at least one of the first plate and the second plate relative to a patient in use.

10. The surgical cutting guide of claim 9, wherein the edge portion defines a curved surface with a notch.

11. The surgical cutting guide of claim 3, wherein the base member further defines an impaction surface and the first opening and the second opening are each configured to allow access to the impaction surface.

12. The surgical cutting guide of claim 1, 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.

13. The surgical cutting guide of claim 12, wherein the first substantially planar surface and the second substantially planar surface meet at an edge parallel to the line of intersection.

14. The surgical cutting guide of claim 1, wherein the base member further comprises a pair of outwardly extending arms positioned opposite each other.
