Abstract
A wedge guide system of variable but precise angular dimensions that allows the excision of a precise bony wedge by the alternate use of arcuate (crescentic) and planar saws in a stable and accurate manner. Right and left sided wedges can be taken. The precise wedge can be angulated in respect to the long axis of the bone by a directional guide structure that complies with data for each surgical case enabling the surgeon to make triplanar bone corrections.
