Abstract
Thirty wrists of 27 patients with ulnar impaction syndrome who underwent ulnar shortening osteotomy were retrospectively reviewed. The average follow-up was 51 months. The wrists were graded preoperatively and postoperatively according to a wrist-grading system modified from Gartland and Werley. The parameters of grading included pain, function, range of motion, grip strength, radiographic analysis, bony union, and complications. Twenty-four wrists were graded excellent, 4 good, 1 fair, and 1 poor after the surgery in comparison with 28 poor and 2 fair before the operative treatment. Complications were rare, with no ulnar nonunions. This long-term follow-up study revealed that distal ulnar shortening osteotomy is an excellent procedure for the treatment of ulnar impaction syndrome.
