Pectoralis major transfer for serratus anterior paralysis.
Serratus anterior paralysis can result in winging of the scapula and weakness of arm elevation. The etiology of the condition is injury to the long thoracic nerve. There are many proposed causes of long thoracic nerve injury including acute trauma, Parsonage-Turner syndrome, or viral illness. The long length of the long thoracic nerve makes it prone to compression injury along the chest wall. Most patients recover nerve function with conservative treatment. In those in whom nerve function fails to recover, surgical treatment involving pectoralis major transfer may be beneficial. In this study 9 patients underwent pectoralis major transfer with a fascia lata extension graft. The symptoms of most were improved, with correction of the winging and improved movement in the affected shoulder.
