Abstract

An apparatus for guiding the resection of the head of a humerus is provided. The apparatus includes a base, a cut block, and a stylus. The guide is used in connection with a reamer or other tool that is inserted into the intramedullary mayal of the humerus with the shank of the reamer extending superiorally above the head of the humerus to establish the axis of the humerus. The base is in rotatable connection with the reamer. The cut block is removably attached to the guide and has a component for receiving a saw blade. The stylus attaches to the cut block, preferably by engaging the component for receiving the saw blade, and extends around the articular margin of the humeral head to aid in setting height and version.
