Long oblique ulna shortening osteotomy jig

摘要

An ulnar osteotomy jig and method for use of said jig for the correction of ulnar impaction syndrome. The jig in cross section is shaped substantially like a right triangle. It has a flat top, a concave bottom which is adapted to closely conform to the surface of an ulna, two flat leg surfaces, and a flat hypothenuse surface. Two holes are defined in the jig and extend between the top and bottom surfaces. When in use, the jig is secured to an ulna with two surgical screws which pass through the holes defined in the jig. A surgeon cuts the ulna with a bone saw into two pieces using the hypothenuse side of the jig as a guide. The two cut ends of the ulna pieces will be repositioned, thereby adjusting the ulna to the proper length and the ulnar pieces will then be secured together with surgical screws.
