AbstractA retrospective review was performed that compared the results of 2 different surgical treatments for ulnar impaction syndrome in 22 patients over a 6-year period. Ulnar shortening osteotomy and wafer distal ulna resection (wafer resection procedure) were each performed in 11 patients based on the preference of 3 individual hand surgeons. All patients presented with ulnar wrist pain and positive ulnar variance on either neutral rotation or pronated-grip x-rays and each failed conservative management. At a minimum follow-up time of 18 months, 9 patients had good to excellent results following ulnar shortening osteotomy compared with 8 following the wafer resection procedure. This difference was not statistically significant. All patients regained functional wrist motion and 21 of the 22 patients had satisfactory pain relief. There was 1 poor result in the wafer group that required revision to complete resection of the distal ulna. Five secondary procedures were required in the osteotomy group to remove painful hardware and union was delayed in 2 patients. Although ulnar shortening osteotomy provides effective treatment for ulnar impaction syndrome, the wafer resection procedure provides favorable pain relief and restoration of function but without the potential for nonunion or hardware removal.
