Abstract
The present invention encompasses a device for providing a wedge osteotomy comprising an osteotomy guide having a guide body that provides reference slots at specific angles to one another and which define planes, all of the planes meeting at a predetermined line of intersection. The slots are employed to properly position resection blocks, which are placed against the bony surface into which the osteotomy is to be cut. The resection blocks have saw blade guiding slots defining the desired planes in which cuts are to be made and which guide s surgical saw blade during a cutting operation. Through the use of a calibrated guide pin, the guide body is so oriented as to position the planes of the cuts so that they intersect at a predetermined line of intersection adjacent the medial surface of the tibia, thereby providing an uncut bone bridge of the desired width and orientation.
