Abstract
Abstract The bone saw guide of this invention allows precise perpendicular or angular cutting of a bone with a conventional bone saw. An inverted U-shaped blade guide portion positions the blade and an upstanding saw guide portion guides the neck of the saw. A plate connects the two portions. The invention allows a bone segment to be removed and the cut ends to be compressed together to shorten the bone.
