Glenoid alignment guide and method of use.

摘要

A glenoid alignment guide (30) for aligning a drill bit relative to the glenoid and the glenoid neck of a patient. The alignment guide comprises a retractor plate (32) for displacing the posterior and superior aspect of the deltoid muscle, and a drill guide (40) slidably movable along the retractor plate. The tip (36) of a narrow, curved finger (34) on the retractor plate is adapted to engage the bone of the glenoid neck to form a fulcrum for levering the muscle and other tissue clear of the glenoid. When the tip of the retractor plate engages the glenoid neck and the drill guide is advanced along the retractor plate against the glenoid face, the drill guide is adapted to guide a drill bit to make a hole from the glenoid face into the glenoid neck along the axis of the glenoid neck. This hole is then used to receive a fastener or locating peg of a glenoid component of a shoulder implant. The method of using the alignment guide is also disclosed.
