Abstract

A resection guide can be configured to guide a resection tool toward a graft source or a tissue body. The resection guide can include a resection guide body with at least one opening, and a guide member configured to be at least partially inserted into the at least one opening.

First claim

What is claimed:

1. A resection guide configured to guide a resection tool toward a graft source, the resection guide comprising a resection guide body that defines:
an upper body surface;
a lower body surface opposite the upper body surface and elongate along a longitudinal direction, the lower body surface being concave from a first terminal edge of the lower body surface to a second terminal edge of the lower body surface in a plane that is normal to the longitudinal direction;
a first resection guide opening that extends through the resection guide body from the upper body surface to the lower body surface; and
a second resection guide opening that is spaced from the first resection guide opening along the longitudinal direction and that extends through the resection guide body from the upper body surface to the lower body surface, each of the first and second resection guide openings defined by a pair of opposed inner side surfaces of the resection guide body that face one another and a pair of opposed inner end surfaces of the resection guide body that face one another such that (i) the first resection guide opening extends along a first plane that is parallel to the inner side surfaces of the first resection guide opening, (ii) the second resection guide opening extends along a second plane that is parallel to the inner side surfaces of the second resection guide opening, and (iii) the longitudinal axis intersects and passes through the first and second planes,
wherein the resection guide body has a minimum distance from the first resection guide opening to the second resection guide opening along the longitudinal direction that is greater than a distance from the first terminal edge to the second terminal edge along the select direction.

2. The resection guide according to claim 1 , further comprising at least one guide member configured to be at least partially inserted in at least one of the first and second resection guide openings, such that at least a portion of the least one guide member is aligned with the inner side surfaces and inner end surfaces of the at least one of the first and second resection guide opening along the longitudinal direction, the at least one guide member having a guide member body and a guide member opening that extends through the guide member body, the guide member opening being elongate along a graft resection axis and being configured to receive at least a portion of the resection tool such that the guide member guides the resection tool along the graft resection axis when the resection tool is received in the guide member opening.

3. The resection guide according to claim 2 , wherein the resection guide body is at least partially made from a first material and the at least one guide member is at least partially made of a second material that is harder than the first material.

4. The resection guide according to claim 3 , wherein the second material has a Brinell hardness ranging between about 10 HB and about 200 HB.

5. The resection guide according to claim 4 , wherein the second material has a Brinell hardness of about 120 HB.

6. The resection guide according to claim 3 , wherein the second material is metallic.

7. The resection guide according to claim 6 , wherein the first material is polymeric.

8. The resection guide according to claim 6 , wherein at least a portion of the at least one guide member is removably disposed in the first resection guide opening or the second resection guide opening.

9. The resection guide according to claim 2 , wherein the guide member body defines a front wall, a rear wall opposite to the front wall, and a pair of side walls that extend from the front wall to the rear wall, wherein the front wall, the rear wall and the pair of side walls at least partially define the guide member opening.

10. The resection guide according to claim 2 , wherein the guide member is metallic and is configured to be selectively inserted into each of the first and second resection guide openings.

11. The resection guide according to claim 1 , wherein the resection guide body defines at least one drill guide opening that extends through the resection guide body from the upper body surface to the lower body surface, wherein the at least one drill guide opening is spaced from the first and second resection guide openings.

12. The resection guide according to claim 1 , wherein the graft source is a long bone.

13. The resection guide according to claim 1 , wherein the resection guide body further defines a third resection guide opening that is spaced entirely from the first and second resection guide openings along the longitudinal direction, that extends through the resection guide body from the upper body surface to the lower body surface, and that is defined by a respective pair of opposed inner side surfaces that face one another and a respective pair of opposed inner end surfaces that face one another.

14. The resection guide according to claim 13 , wherein the third resection guide opening extends along a third plane that is parallel to the pair of inner side surfaces of the third resection guide opening such that the longitudinal axis intersects and passes through the third plane.
