Abstract
A cannulated offset drill guide and surgical methods for repairing Bankart lesions. The cannulated offset drill guide comprising a shaft which is offset from the guide center line by about 1 to 3 mm, more preferably of about 1.5 mm. The cannulated offset drill guide is provided at its proximal end with a concave clear tip which allows a surgeon to visualize the drill and the insertion of an anchoring device, for example a suture anchor. The concave clear tip has beveled, smooth edges to prevent damage to adjacent bone and tissue, and to avoid damage to the rubber dam of the cannula through which the offset drill guide is inserted. The configuration of the concave clear tip is designed to engage and match the generally convex-curve articulating face of the glenoid, and to precisely aligning the offset drill guide with the glenoid face. The clear tip may also be employed in a standard drill guide having a shaft which is not offset from the center line of the guide.
