Abstract
A method and apparatus for performing an upper tibia osteotomy comprising cutting a wedge from the bone using a first guide assembly to cut a first slot partially through a bone and a second guide assembly to cut a second intersecting slot to define a wedge shaped bone segment. An external compressor device draws the osteotomy closed by plastic deformation of the unsevered portion of the bone. The bone is secured by a plate and screws.
