Long oblique ulna shortening osteotomy jig

A method of surgically correcting ulnar impaction syndrome, comprising the steps of:

• a) providing a jig having a longitudinal cross-section shape like a substantially right triangle, a flat top surface, a concave bottom surface adapted to closely conform to the surface of an ulna bone, a flat hypothenuse side surface, a first flat leg side surface, a second flat leg side surface and two holes defined through the jig and extending between the top surface and the bottom surface;
• b) placing the bottom surface of said jig securely against the ulna to be operated on with the concave bottom surface conforming to the surface of the ulna;
• c) securing said jig to the ulna with two surgical screws positioned in the holes defined in said jig;
• d) obliquely cutting said ulna into two pieces with a bone saw using the hypothenuse side of said jig as a cutting guide;
• e) removing said jig from the ulna;
• f) sliding the two pieces of the ulna past one another such that the overall length of the ulna is shortened to alleviate the symptoms of ulnar impaction syndrome;
• and
• g) securing the pieces of said ulna together with a plurality of countersunk surgical screws.
