Method and apparatus for corrective osteotomy

A gauge for use in an arcuate osteotomy procedure comprising:

• a central member provided with a pair of spaced, depending arms adapted to fit on either side of the bone on which the osteotomy is to be performed for the purpose of determining the center axis, radius, and position of a cut through the bone, said central member being provided with a central alignment index point for locating the center axis of said arcuate cut through said bone, while the spacing of said arms gauges the length of the chord demarcating the arcuate cut.

A gauge for use in an arcuate osteotomy procedure comprising:

• a longitudinal arm for disposition generally along a bone upon which an osteotomy is to be performed, and a crossbar joined to said longitudinal arm, said crossbar having a length approximating the length of a chord demarcating an arcuate bone cut to be made during said procedure, said crossbar having spaced, depending arms at the ends thereof adapted to fit on either side of the bone on which the osteotomy is to be performed for the purpose of determining the center axis, radius, and position of the cut, said crossbar providing a central alignment index point for positioning the center axis of a semi-cylindrical saw for making said arcuate cut.
