REPAIR OF ISOLATED AXILLARY NERVE LESIONS AFTER INFRACLAVICULAR BRACHIAL-PLEXUS INJURIES - CASE-REPORTS

Stretch injuries of the infraclavicular brachial plexus have a much better prognosis for spontaneous recovery than do their supraclavicular counterparts. We present three patients with stretch injuries of the infraclavicular brachial plexus who had spontaneous restoration of function in all muscles except the deltoid. Decreased shoulder abduction was a serious handicap to these individuals. At surgical exploration, each patient had an isolated, complete axillary nerve disruption at the quadrilateral space. Deltoid muscle function was restored in all three patients by repair of the axillary nerve with sural nerve grafts across the quadrilateral space.
