cord is the most common pattern of injury (~72% prevalence of at least 1 root avulsion) which requires surgery to reanimate the arm. Prognosis The site and type of brachial plexus injury determine the prognosis. Avulsion and rupture injuries require timely surgical intervention for any chance of recovery. Equally, reconstruction of elbow flexion in patients with pan-plexus injuries should be performed as soon as possible, because delays lead to worse motor outcomes. For milder injuries involving buildup of scar tissue and for neurapraxia, the potential for improvement varies, but there is a fair prognosis for spontaneous recovery, with a 90–100% return of function.
