Particularly challenging after complete brachial plexus avulsion is reestablishing effective hand function, due to limited neurological donors to reanimate the arm. Acute repair of avulsion injuries may enable reinnervation strategies for achieving hand function. This patient presented with pan-brachial plexus injury. Given its irreparable nature, the authors recommended multistage reconstruction, including contralateral C-7 transfer for hand function, multiple intercostal nerves for shoulder/triceps function, shoulder fusion, and spinal accessory nerve-to-musculocutaneous nerve transfer for elbow flexion. The video demonstrates distal contraction from electrical stimulation of the avulsed roots. Single neurorrhaphy of the contralateral C-7 transfer was performed along with a retrosternocleidomastoid approach. The video can be found here: .

Particularmente desafiante después de la avulsión completa del plexo braquial está restableciendo la función de la mano efectiva, debido a los donantes neurológicos limitados para reanimar el brazo. La reparación aguda de lesiones por avulsión puede permitir estrategias de reinervación para lograr la función de la mano. Este paciente presentó una lesión del plexo pan-braquial. Dada su naturaleza irreparable, los autores recomendaron la reconstrucción de múltiples etapas, incluida la transferencia C-7 contralateral para la función de la mano, múltiples nervios intercostales para la función hombro / tríceps, fusión de hombro y la transferencia nerviosa espinal-musculocutánea espinal para la flexión del codo. El video muestra la contracción distal de la estimulación eléctrica de las raíces avulsionadas. La neurorrafia simple de la transferencia contralateral C-7 se realizó junto con un abordaje retrosternocleidomastoideo.

Brachialis to Anterior Interosseous Nerve Transfer with Extended Forearm Incision
Standard Edition (140312.140314)



Loss of flexor pollicis longus and radial profundus function results in a deficit of pinch and reduced grip strength in the hand. This palsy can be isolated or commonly included in a lower brachial plexus injury. The brachialis nerve is an available, synergistic, and powerful donor for transfer in these scenarios, especially in C7,8,T1 injuries and when other common donors are unavailable due to injury like the extensor carpi radialis brevis. In this case, the patient presented three months following a partial C7 and C8,T1 brachial plexus injury from a fall with no recovery on electrodiagnostic studies. The brachialis to anterior interosseous nerve transfer was elected with the supinator to flexor digitorum superficialis nerve transfer and lateral antebrachial cutaneous to ulnar sensory nerve transfer. This video details the specifics for the brachialis transfer with an extended incision into the forearm to confirm the proximal topography of the anterior interosseous fascicle in the median nerve. Additionally, this patient has an anomalous sensory nerve anastomosis from a brachialis nerve branch to the sensory component of the median nerve.
