Abstract:
An apparatus for modeling a skeletal structure before and after a surgical procedure is performed on the structure, the apparatus comprising:a base, the base including a generally planar surface; first and second bone members coupled to the base, the bone members representing bones involved in the surgical procedure, wherein the second bone member is movably coupled to the first bone member to simulate a skeletal joint, with the second bone member being movable between an extended position and a flexed position relative to the first bone member; and at least one bone portion movably coupled to the bone member, the bone portion representing a part of the bone involved in the surgical procedure that is repositioned in the surgical procedure from a preoperative position to a postoperative position; wherein the bone portion may be selectively moved between a preoperative position, representing the position of the part of the bone before the surgical procedure is performed, and a postoperative position representing the position of the part of the bone after the surgical procedure is performed; and a spring coupled between the base and the second bone member to urge the second bone member into one of the extended position and the flexed position.
