ABSTRACT:
The present invention is a simple machine that permits the concentrated application of a bending moment to a stiff metallic bone plate. The present invention permits bends along three orthogonal torsional axes. The present invention can be scaled so that modest sized operators can bend the most stout bone plates. The bending moments are transmitted to the bone plates through the edges of curved apertures so that the built in transverse curvature of the plate is not crushed with resulting weakening of the plate. Finally, the apertures are rotated and angled to provide comfortable hand clearance and to permit efficient application of muscle force by the operator.
