This overloading occurs as a result of the distal ulnar articular surface being more distal than the ulnar articular surface of the distal radius. This situation has been termed positive ulnar variance, and it can quickly lead to ulnar-sided wrist degenerative changes and functional losses. Patients often have vague, ulnar-sided complaints of chronic pain and swelling with an insidious onset that does not correlate with any specific traumatic event. Many procedures have been developed to alleviate this condition, but the gold standard for correcting positive ulnar variance is the ulnar shortening osteotomy. The goals of the shortening procedure are to relieve pain and prevent arthritis by reestablishing a neutral or slightly negative ulnar variance. We describe a new plate and compression system in which an oblique ulnar diaphyseal osteotomy is both completed and stabilized through the same jig-based system. © 2007 Lippincott Williams & Wilkins, Inc.
