ABSTRACT:
A bone cutting device for precision elbow surface replacement arthroplasty and osteotomy is described. A humeral clamping device is provided with an outrigger to hold the ulna in preselected and rigid relation to the humerus. A bond cutting tool such as a burr is inserted into a selected guide sleeve mounted for oscillatory arcuate movement on the medial side of the clamping device, so as to precisely prepare the humerus. The humeral guide sleeve is removed and replaced with a slightly longer second sleeve which provides the precise spacing required to prepare the ulna in similar manner. A planar radial cutting guide may be mounted on the lateral side of the clamping device, to guide a planar oscillating saw used to prepare the proximal end of the radius.
