Method for performing a high tibial osteotomy
First Claim
1. A method for performing an osteotomy procedure on a bone having a first side and a second side, comprising the steps of:
- making a first cut in the bone extending in a first direction from an outside surface on the first side of the bone to a first line being disposed within the bone and extending in a second direction orthogonal to the first direction substantially through the bone;
making a second cut in the bone extending in a first direction from an outside surface on the second side of the bone to a second line being disposed within the bone and extending in a second direction orthogonal to the first direction substantially through the bone, wherein the second cut is spaced apart from the first cut along a longitudinal axis of the bone; and
making a third cut in the bone extending in a first direction from an outside surface on the first side of the bone to a third line near being disposed within the bone and extending in a second direction orthogonal to the first direction substantially through the bone, wherein the first cut and third cut form an intersecting angle therebetween along the respective first directions thereof such that an apex is formed along a the third line.

Abstract
A cutting block for use in a bone osteotomy procedure is disclosed, and includes a first cutting guide surface, a second cutting guide surface, and a third cutting guide surface. The first, second, and third cutting guide surfaces are adapted to be temporarily affixed to a bone having a first side and a second side such that the first cutting guide surface is disposed on the first side of the bone, and such that the second cutting guide surface and third cutting guide surface are disposed on the second side of the bone forming an angle therebetween.

37. A method for performing a high tibial osteotomy comprising:
-
making a first cut in a proximal tibia in a first plane; making a second cut in a proximal tibia in a second plane, said first and second planes spaced in a proximal-distal direction; making a third cut in the proximal tibia in a third plane, said third plane at an angle with and intersecting one of said first and second planes, said first, second and third cuts open to a medial or lateral side of the proximal tibia; removing a bone wedge formed by said intersection of said third cut with said one of said first or second cuts; closing a wedge shaped opening formed by the removal of the bone wedge by rotating the proximal tibia about an anterior to posterior axis to open the one of said first and second cuts not intersecting with said third cut; and inserting the bone wedge into said one of said first and second bone cuts opened by the rotation about the anterior-posterior axis. - View Dependent Claims (38, 39)
