Contralateral brachial plexus neuropathy after arthroscopic shoulder surgery.

Abstract

This case report presents a neurologic complication that occurred after shoulder arthroscopic surgery on the contralateral arm. This brachial plexus palsy has been documented as a reversible C7-T1 lesion, which was the consequence of the patient's unknown cervical rib and the applied lateral position during the operation. In this case, the recovery was almost complete within 3 months postoperatively; however, one should take care to prevent these complications with an appropriate positioning of patients with an anatomic variant.
