The Prespinal Route in Contralateral C7 Nerve Root Transfer for Brachial Plexus Avulsion Injuries

Contralateral C7 nerve root transfer for brachial plexus injury is described, passing the nerve through a subcutaneous tunnel on the anterior surface of the neck and chest. We recommend passing the nerve graft through the retropharyngeal space. This route has the benefits of a simpler dissection, a shorter distance and protected placement of the graft. It has been used in one clinical case.
