Abstract

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.

First claim

What is claimed is:

1. A surgical method comprising:
attaching a plate to an anterior surface of a vertebra;
creating an access channel only in the vertebra through an opening in the plate, the access channel extending through the anterior surface of the vertebra and through a posterior surface of the vertebra without entering an adjacent disc space; and
removing a source of compressing neural pathology through the access channel.

2. The surgical method of claim 1 , wherein attaching the plate to the anterior surface of the vertebra is performed via a control sleeve.

3. The surgical method of claim 2 , wherein the control sleeve comprises an internal cylinder.

4. The surgical method of claim 1 , wherein creating the access channel in the vertebral through the plate is performed via a cutting tool.

5. The surgical method of claim 4 , wherein the cutting tool comprises at least one of a drill, burr, reamer or trephine.

6. The surgical method of claim 1 , wherein removing the source of compressing neural pathology through the access channel comprises removing osteophytes.

7. The surgical method of claim 1 , further comprising inserting an implantable bone repair device into the access channel to repair a vacancy in the vertebra created by the access channel.

8. The surgical method of claim 7 , wherein the repair device comprises a cylindrical shaft and abutting surface.

9. The surgical method of claim 1 , wherein the plate comprises a first opening and a second opening.

10. The surgical method of claim 9 , wherein the first opening is sized and configured to receive a retention screw and the second opening is sized and configured a bone cutting device therethrough.

11. A surgical method comprising:
attaching a plate to an anterior surface of a vertebra;
creating an access channel only in the vertebra through an opening in the plate, the access channel extending through the anterior surface of the vertebra and through a posterior surface of the vertebra without entering an adjacent disc space;
removing a source of compressing neural pathology through the access channel; and
repairing the access channel following removal of the source of compressing neural pathology.

12. The surgical method of claim 11 , wherein attaching the plate to the anterior surface of the vertebra is performed via a control sleeve.

13. The surgical method of claim 12 , wherein the control sleeve comprises an internal cylinder.

14. The surgical method of claim 11 , wherein creating the access channel in the vertebral through the plate is performed via a cutting tool.

15. The surgical method of claim 14 , wherein the cutting tool comprises at least one of a drill, burr, reamer or trephine.

16. The surgical method of claim 11 , wherein removing the source of compressing neural pathology through the access channel comprises removing osteophytes.

17. The surgical method of claim 11 , wherein repairing the access channel comprises an implantable bone repair device into the access channel to repair a vacancy created by the access channel.

18. The surgical method of claim 17 , wherein the repair device comprises a cylindrical shaft and abutting surface.

19. The surgical method of claim 11 , wherein the plate comprises a first opening and a second opening.

20. The surgical method of claim 19 , wherein the first opening is sized and configured to receive a retention screw and the second opening is sized and configured a bone cutting device therethrough.
