Intercostal nerve transfer for brachial plexopathy.
Thirteen patients with traumatic brachial plexopathy underwent intercostal nerve transfer to the biceps motor branch (9 patients) or combined gracilis muscle and intercostal nerve transfer (4 patients; 3 for elbow flexion and 1 for elbow extension). Follow-up time ranged from 12 to 48 months (mean, 25 months) on 12 patients. Useful elbow flexion or extension was obtained in a total of 9 patients. Comparison of pre- and postoperative spirometry in 4 patients demonstrated a mild decline in pulmonary function, although there was no subjective change in respiratory status. Intercostal nerve transfer and combined gracilis muscle and intercostal nerve transfer are viable, although technically demanding, alternatives for restoring active elbow motion in patients with irreparable brachial plexus lesions when conventional tendon transfers are not feasible. The morbidity of intercostal nerve harvest with respect to pulmonary function is minimal.
