Abstract
- Elbow flexion is the first goal in upper partial brachial plexus palsy treatment. However, elbow extension is essential for daily living activities. To recover this function, one fascicle of ulnar nerve can be transferred to the branch of the long head of the triceps, but this procedure has been previously published in only two patients. The goal of our study is to assess a larger series of transfers of one fascicle of ulnar nerve to the branch of the long head of the triceps to help patients recover elbow extension. Ten male patients with C5, C6 and C7 brachial plexus injuries underwent operation. For shoulder recovery, we transferred the spinal accessory nerve and rhomboid nerve. For elbow flexion, one fascicle of median nerve was transferred to the nerve of the biceps. For elbow extension, we transferred one fascicle of ulnar nerve to the branch of the long head of the triceps. Tendon transfers were performed for wrist and finger extension. Nine patients recovered M4 elbow flexion and extension. One patient had M3 elbow extension and flexion. Average active shoulder elevation was 85° and average active shoulder external rotation was 65° All patients recovered finger and wrist extension. The classical techniques of grafts or phrenic or intercostal nerve transfers to recover elbow extension are not always reliable, according to the literature. Because the harvested ulnar nerve motor fascicle is close to the branch of the long head of the triceps, the recovery time for this procedure is shorter than that of other described nerve transfers. The isolated recovery of the reinnervated long head of the triceps muscle excludes spontaneous recovery occasionally noted in upper root plexus injuries. The transfer of one fascicle of ulnar nerve to the branch of the long head of the triceps is reliable for active elbow extension recovery in C5, C6 and C7 brachial plexus palsies.<br /> (Copyright © 2019.
