Preoperative and postoperative ulnar length, ulnar shortening, percentage of ulnar shortening, carpal slip. (A) Average preoperative ulnar length was 168.0 mm, and 202.7 mm at the last follow up. (B) Average preoperative ulnar shortening was 29.7 mm, and -1.0 mm at the last follow up. (C) Average preoperative percentage of ulnar shortening was 17.5%, and -0.3% at the last follow up. (D) The average preoperative carpal slip was improved, preoperatively 69.5%, and most recent follow up 43.9%. Testing for statistical significance was performed using the Wilcoxon signed rank test, but we found no statistical significance.
