Abstract
A device for guiding an osteotomy to be performed on the proximal end of a humerus that has a proximal sawguide alignable on a selected surface of the proximal end of the humerus for defining a saw line thereon; a radial arm connecting the sawguide to a distal mechanism for stably aligning the sawguide, the distal alignment mechanism has a pair of opposing lateral and medial epicondyle arms pivotally engageable with the lateral and medial sides of the distal end of the humerus, the epicondyle arms being pivotally mounted in a distal cross arm, the distal end of the radial arm being slidably mounted in the cross arm for distal to proximal slidable movement therein; the proximal end of the radial arm being rotatably connected to the sawguide through a proximal guide bar; the radial arm being supported above the humerus by the proximal guide bar and the epicondyle arms.
