Abstract
An apparatus for guiding the resection of the head of a humerus is provided. The apparatus includes an intramedullary alignment member having a longitudinal axis and structured for substantial axial alignment with the intramedullary canal of the bone, one point of reference for the resection. The apparatus also includes an extramedullary alignment member and a collar rotatably mounted on the intramedullary member for rotating the extramedullary alignment member about the longitudinal axis of the intramedullary alignment member to a desired degree of retrotorsion. A cutting block and a first shaft and a second shaft in a perpendicular orientation relative to the first shaft for positioning the cutting block in a desired orientation relative to the head of the bone are also provided.
