ABSTRACT
BACKGROUND:
This study evaluated the functional outcomes of bipolar pedicled pectoralis major (PM) transfer to restore elbow flexion.METHODS:
We retrospectively reviewed 29 transfers in 28 patients with a mean age of 31.2 years (range, 5-65 years). The loss of elbow flexion was due to brachial plexus palsy in 24 patients, elbow flexors necrosis in 4, and poliomyelitis in 1. The entire PM muscle was mobilized and fixed proximally to the coracoid process. Intraoperative positioning and postoperative immobilization of the shoulder and the elbow flexed at 60° and 120°, respectively, allowed direct distal fixation of the muscle to the biceps brachii tendon.RESULTS:
At the last follow-up (mean, 13 months; range, 4-37 months), 41% of the transfers (n = 12) recovered grade 4 elbow flexion strength and were able to lift 2.2 kg on average (range, 0.5-5 kg), 52% (n = 15) recovered grade 3 strength, and 7% (n = 2) had a poor result (ie, grade 2 elbow flexion). The mean active elbow flexion was 100° (ranging, 30°-150°), and the patients had 0° to 10° elbow flexion contracture.CONCLUSIONS:
Our results indicate that bipolar PM transfer is a reliable and effective procedure to restore elbow flexion. Flexion of the shoulder and elbow allowed the transfer to reach the elbow fold and avoided an interposition graft between the distal PM and the biceps brachii tendon.Palavras-chave
