Transfer of the superior portion of the pectoralis major flap for restoration of shoulder abduction.

Shoulder function is frequently impaired or lost following brachial plexus injuries. We introduce a novel method of restoring shoulder abduction by transferring the superior portion of the major flap of the pectoralis. Between March 1998 and June 2003, eight patients with insufficient abduction of the shoulder joint were treated with transfer of the superior portion of the pectoralis major flap. The mean follow-up period was 6 years. In all cases, shoulder mobility was improved. The mean increase in active abduction was from 6 degrees to 74 degrees. The mean forward flexion increased from 10 degrees to 75 degrees, and subluxation was abolished. All patients were satisfied with their improvement in function. Transfer of the superior portion of the pectoralis major flap is an easy and practicable method to restore abduction without serious complications. The patients achieved good stability and functionality of the shoulder.
