Preoperative computer simulation in all patients. Preoperative computer simulations in all patients are shown (from case 1 to 10). The result of case 11 is shown in Fig. 1. The impingement area was computed at elbow flexion angles of 0° and 140°, and shown in red. Preoperative clinical data of extension and flexion angles are shown below
