Preoperative and postoperative radial length, radial bowing, percentage of radial bowing, radial articular angle. (A) Average preoperative radial length was 170.5 mm, and 174.2 mm at the last follow up. (B) Average preoperative radial bowing was 16.0 mm, and 13.2 mm at the last follow up. (C) Average preoperative percentage of radial bowing was 9.9%, and 7.8% at the last follow up. (D) The average preoperative radial articular angle was 40.7 degree, and 37.5 degree at the last follow up. Testing for statistical significance was performed using the Wilcoxon signed rank test, but we found no statistical significance.
