Abstract

A system for establishing an intramedullary path includes a body sized and configured to be received within a resected bone space. The body defines a first aperture that extends through the body and is sized and configured to receive a surgical tool therethrough. A first bone engaging structure extends from the body in a first direction and includes a first surface that is complementary to a surface topography of a first bone. When the first surface of the bone engaging structure engages the surface topography of the first bone to which the first surface is complementary, an axis defined by the first aperture is substantially collinear with a mechanical axis of the first bone.

Claims

1. A system, comprising:

a foot holder assembly, comprising;

a base plate;

at least one rod extending from the base plate; and

a mounting member defining at least one hole at a first end sized and configured to receive the at least one rod therethrough, the mounting member configured to position a drill guide with respect to the base plate, and further comprising;

a mount having a hollow interior and including;

a first side, a second side, a third side, and a fourth side, the first side being spaced apart from the second side, the third side being spaced apart from the fourth side, and the third and fourth sides each extending between the first and second sides;

an engagement structure extending from the third side and including a conformal engagement surface for mating to a surface topography of at least a portion of a bone,

wherein each of the first, third, and fourth sides of the surgical mount define a respective aperture that communicates with the hollow interior, and

wherein the mount is configured to be coupled to the mounting member of the foot holder assembly.

2. The system of claim 1 wherein the base plate extends between a first end and a second end, and wherein at least one of the first end or the second end define a hole.

3. The system of claim 1 wherein the hole is sized and configured to removably couple a drill bushing to the base plate.

4. The system of claim 1 wherein each of the first end and the second end define a hole.

5. The system of claim 1 wherein the base plate comprises an extension coupled to the first end and the second end extending in a substantially perpendicular direction to the first end and the second end.

6. The system of claim 5, wherein the extension is coupled to an approximate mid-point between the first end and the second end.

7. The system of claim 1 wherein the mounting member defines one or more holes at a second end configured to correspond to one or more holes formed in the drill guide.

8. The system of claim 1, wherein the second end of the mounting member defines a slot sized and configured to receive a rod in a pivoting arrangement with respect to the mounting member, and wherein the rod is configured to couple the mounting plate to the mount.

9. The system of claim 1 wherein comprising a first rod and a second rod extending substantially perpendicular to the base plate in a predetermined spaced relationship, and wherein the first end of the mounting plate defines a first hole sized and configured to receive the first rod and a second hole sized and configured to receive the second rod.

10. The system of claim 1 wherein the first end of mounting member includes a locking mechanism configured to lock the mounting member at a selected position along the first and second rods.

11. A system, comprising:

a foot holder assembly, comprising;

a base plate;

a first rod and a second rod extending substantially perpendicular to the base plate in a predetermined spaced relationship; and

a mounting member extending between a first end and a second end, the first end defining a first hole sized and configured to receive the first rod therethrough and a second hole sized and configured to receive the second rod therethrough; and

a mount configured to releasably couple a drill guide to the mounting member, wherein the mount has a hollow interior and includes;

a first side, a second side, a third side, and a fourth side, the first side being spaced apart from the second side, the third side being spaced apart from the fourth side, and the third and fourth sides each extending between the first and second sides;

an engagement structure extending from the third side and including a conformal engagement surface for mating to a surface topography of at least a portion of a bone,

wherein each of the first, third, and fourth sides of the surgical mount define a respective aperture that communicates with the hollow interior, and

wherein the mount is configured to be coupled to the mounting member of the foot holder assembly.

12. The system of claim 11 wherein the mounting plate is configured to releasably couple to the mount, wherein a guide hole formed through a drill guide coupled to the mount is substantially aligned with the hole configured to removably couple a drill bushing to the base plate when the mount is coupled to the mounting plate.

13. The system of claim 11 wherein the first end of mounting member includes a locking mechanism configured to lock the mounting member at a selected position along the first and second rods.

14. The system of claim 11 wherein the base plate extends between a first end and a second end, and wherein at least one of the first end or the second end define a hole sized and configured to removably couple a drill bushing to the base plate.

15. The system of claim 11, wherein the second end of the mounting member defines a slot sized and configured to receive a rod in a pivoting arrangement with respect to the mounting member, and wherein the rod is configured to couple the mounting plate to the mount.

16. The system of claim 11, comprising a cartridge defining at least one slot extending perpendicular with respect to a longitudinal axis of the cartridge, wherein the cartridge is sized and configured to be received within the hollow interior of the mount.

17. A method, comprising:

inserting a drill guide into a space defined between a first bone and a second bone;

coupling a mount to the drill guide; and

coupling the mount to a foot holder assembly, the foot holder assembly comprising a base plate, a first rod and a second rod extending substantially perpendicular to the base plate in a predetermined spaced relationship, and a mounting member extending between a first end and a second end, the first end defining a first hole sized and configured to receive the first rod therethrough and a second hole sized and configured to receive the second rod therethrough, and the second end defining at least one hole configured to releasably couple the mounting member to the mount.

18. The method of claim 17, comprising coupling a drill bushing to the base plate of the foot holder assembly, wherein drill bushing is positioned substantially in alignment with a guide hole formed in the drill guide.

19. The method of claim 18, comprising inserting a surgical instrument through the drill bushing and the guide hole formed in the drill guide.
