Abstract: | PurposeThe gold standard for treatment of ulnar impaction has become ulnar shortening osteotomy. Previous reports in the literature have shown not only good results with relief of ulnar-sided wrist pain but also significant nonunion rates and painful hardware necessitating further surgery and potentially, metal removal. The purpose of this paper is to review the success rate of ulnar shortening osteotomy utilizing a low profile compression plate designed specifically for ulnar shortening osteotomy.MethodsNinety-three patients with ulnar abutment syndrome underwent ulnar shortening osteotomy with the low profile osteotomy plate. There were 47 males and 46 females. The Acumed’s ulnar shortening system was utilized in all cases. The patients were evaluated for pain, range of motion, grip strength, return to work, time to union, and hardware removal. The patients’ results were validated using the Mayo Wrist Score.ResultsThere was a 100 % union rate in the 93 patients. There were no nonunions or delayed unions, or any hardware removal. All patients noted an improvement in their ulnar-sided wrist pain. Utilizing the Mayo wrist classification, the average postoperative score was 84.5. The average preoperative Mayo score was 49.4, for an average increase of 35.1 points.ConclusionThe Acumed’s low-contact plate designed specifically for ulnar shortening osteotomy demonstrated 100 % union rate and no implant removal in our series. This is the largest study to our knowledge of a series of ulnar shortening osteotomies and successful healing without the removal of any implants. Furthermore, the specifically designed ulnar shortening osteotomy plate significantly simplifies the procedure for the surgeon and improves patient outcomes with relief of ulnar-sided wrist pain. |
