Abstract: An apparatus for modeling a skeletal structure before and after a surgical procedure is performed on the structure. The apparatus comprises a base, the base including a generally planar surface, at least one bone member coupled to the base, the bone member representing a bone involved in the surgical procedure, 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. 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. The bone member may be coupled to the base generally parallel to the surface of the base.

Abstract: A joint support is attachable to a limb of an animal to limit movement of an associated limb joint substantially about a single axis. The joint support includes a radial element having a longitudinal axis and a transverse element having a longitudinal axis. The transverse element is pivotally connected to the radial element about an axis of rotation. The longitudinal axis of the radial element substantially intersects with the axis of rotation, and radial rotation of the radial element is restricted about the axis of rotation. The longitudinal axis of the transverse element is partially fixed relative to the radial element so that the same is substantially coplanar with the longitudinal axis of the radial element and substantially offset from the axis of rotation.
