Abstract
A new set of surgical instruments is described which provides a movable constraint such that the instruments include a saw guide which may be used in either a constrained or unconstrained fashion. The instruments have a movable restraint which, in the down position provides a continuous surface with the remainder of the instrument for guiding a saw, and when in the up position provides a constrained slot for guiding the saw of a surgeon in making cuts in prosthesis implantation surgery.
