title: Osteotomy of the humerus to improve external rotation in nine patients with brachial plexus palsy.
abstract: Malfunction of the infraspinatus muscle and teres minor muscle illustrate the typical clinical picture in patients with brachial plexus palsy. The arm hangs down in an inwardly rotated position and elbow flexion is hindered by striking of the lower arm against the thorax. Between 1995 and 2000, we have done external rotational osteotomy of the humerus for nine patients with brachial plexus palsy. The mean age of the patients at the time of operation was 29 years (range 15 to 42). The mean follow-up time was 24 (6 to 69) months. Preoperatively, the patients all had appreciable deficits of external rotation (mean deficit 37 degrees, range 10 degrees to 70 degrees). As a result of osteotomy, external rotation was improved in all patients, the mean increase being 42 degrees (range 25 degrees to 60 degrees). All patients were subjectively content with the improved position of the arm and its function. They were able to move their hands to their faces without striking the lower arm against the chest on elbow flexion, or without compensatory evasive movement of the shoulder.
