Abstract

A surgical cutting guide is adapted to receive a cutting instrument during a surgical procedure. The surgical cutting guide comprises at least one body portion including a bone engaging surface. A plurality of separate plates are secured to the at least one body portion. At least one cutting slot is formed in the surgical cutting guide between the plurality of separate plates. The at least one cutting slot is configured to receive the cutting instrument and orient the cutting instrument for the surgical procedure. The at least one body portion is comprised of a first material, such as a plastic material, and the plurality of separate plates are comprised of a second material, such as a metal material.

Claims

1. A surgical cutting guide adapted to receive a cutting instrument during a surgical procedure, the surgical cutting guide comprising:

at least one body portion including a bone engaging surface;

a plurality of separate plates secured to the at least one body portion; and

at least one cutting slot formed in the surgical cutting guide between the plurality of separate plates, the at least one cutting slot configured to receive the cutting instrument and orient the cutting instrument for the surgical procedure.

2. The surgical cutting guide of claim 1 wherein the at least one body portion includes a superior body portion and an inferior body portion with the plurality of separate plates trapped between the superior body portion and the inferior body portion.

3. The surgical cutting guide of claim 2 wherein the bone engaging surface is provided on the inferior body portion, and wherein at least one bone fastener extends from the bone engaging surface.

4. The surgical cutting guide of claim 1 wherein the plurality of separate plates include a first plurality of plates that form an angled cutting slot, the angled cutting slot forming an acute angle relative to a plane of the bone engaging surface.

5. The surgical cutting guide of claim 4 wherein the plurality of separate plates include a second plurality of plates that form a perpendicular cutting slot, the perpendicular cutting slot provided generally perpendicular to the plane of the bone engaging surface.

6. The surgical cutting guide of claim 1 wherein the plurality of separate plates include a first cutting plate and a second cutting plate, the first cutting plate including a notch that engages a slotted seat in the at least one body portion, wherein the slotted seat separates the first cutting plate from the second cutting plate.

7. The surgical cutting guide of claim 1 wherein the at least one body portion is comprised of a plastic material.

8. The surgical cutting guide of claim 7 wherein the plurality of separate plates are comprised of a metal material.

9. A surgical cutting guide comprising:

at least one body member comprised of a first material; and

at least one guide member comprised of a second material that is different than the first material, the at least one guide member positioned in the at least one body member such that the at least one guide member provides a wall of a cutting slot formed in the surgical cutting guide.

10. The surgical cutting guide of claim 9 wherein the first material is a plastic material and the second material is a metal material.

11. The surgical cutting guide of claim 9 wherein the at least one guide member is not integral with the at least one body member.

12. The surgical cutting guide of claim 9 wherein the at least one guide member is positioned in a seat formed in the at least one body member.

13. The surgical cutting guide of claim 9 wherein the at least one body member comprises a superior body member and an inferior body member and wherein the at least one guide member is positioned between the superior body member and the inferior body member.

14. The surgical cutting guide of claim 9 wherein the at least one guide member comprises at least one metal plate including fastening features configured to engage complimentary fastening features on the at least one body member.

15. A surgical cutting guide adapted to receive a blade of a cutting instrument during a surgical procedure, the surgical cutting guide comprising:

a block member including an inferior body portion having a bone engaging surface and a superior body portion connected to the inferior body portion;

a plurality of guide members positioned in the cutting block, the plurality of guide members comprised of a different material than the block member; and

at least one cutting slot extending through the block member, wherein the plurality of guide members define opposing walls in the at least one cutting slot, the at least one cutting slot adapted to receive the blade of the cutting instrument.

16. The surgical cutting guide of claim 15 wherein the plurality of guide members include a plurality of angled guide members defining opposing walls of an angled cutting slot that is generally at an acute angle with respect to the bone engaging surface.

17. The surgical cutting guide of claim 16 wherein the plurality of guide members further comprise a plurality of upright guide members defining opposing walls of an upright cutting slot that is generally perpendicular to the bone engaging surface.

18. The surgical cutting guide of claim 15 wherein the plurality of guide members comprise a plurality of plates comprised of a metal material.

19. The surgical cutting guide of claim 15 wherein the plurality of plates are generally rectangular in shape and include seating features configured to engage seats for the plates provided in the cutting block.

20. The surgical cutting guide of claim 15 wherein the at least one of the plurality of guide members is fastened to the block member using a post member that extends from a cavity in the one of the plurality of guide members to a cavity in the block member.
