Nerve Transfers for Elbow Flexion in Traumatic Brachial Plexus Injuries
Abstract
Objective: To evaluate the results of different nerve transfers used for elbow flexion in patients with traumatic brachial plexus injury. Materials and Methods: Between April 2012 and January 2019, 13 patients (12 men) with traumatic brachial plexus injury underwent surgery. 5 patients had total paralysis and did not recover, 4 had total paralysis and partially recovered the lower trunk, and 4 had high paralysis. The nerve transfers performed for elbow flexion were: 3 intercostal nerves with a sural graft to the musculocutaneous nerve or its motor branch(es) (4 patients), 3 intercostal nerves to the musculocutaneous nerve without graft (3 patients), the accessory spinal nerve to motor branches of the musculocutaneous nerve with sural graft (2 patients), fascicles of the ulnarnerve to the motor branch of the biceps (3 patients) and fascicles of the ulnar nerve and fascicles of the median nerve to the motor branches of the biceps and anterior brachialis (3 patients). We assessed elbow flexion strength (M0-M5), pain on the visual analog scale, and DASH score. The average follow-up was 50 months. Results: Elbow flexion strength was M5 (1 patient), M4 (7 patients), M3 (1 patient), M2 (1 patient), and M1 (2 patients). The mean DASH score was 54.1 before surgery and 29.5 postoperatively. The preoperative pain score was 7 and 0.9 postoperatively. There were no complications. Conclusions: Nerve transfers achieved satisfactory outcomes for active elbow flexion reconstruction in patients with brachial plexus injury.Downloads
