ABSTRACT:
A method and apparatus for performing arcuate osteotomies wherein a wedge-shaped correction is filed rather than sawed from the bone. A combined saw and file for use in the method has a curved blade with teeth along a longitudinal edge for making an arcuate cut in the direction perpendicular to the edge, and file teeth on one or both of its curved faces for filing out the correction. The effective width of the the blade determines the tip width of the correction; the thickness of the blade determines the width of the arcuate kerf; and the radius of curvature of the blade determines the radius of the arcuate cut. Also disclosed is cutting guide for guiding a saw/file or other cutting implement to make the arcuate cut and the correction.
