Nerve lesions associated with shoulder dislocation; an electrodiagnostic study of 11 cases

Electrodiagnostic examination of 11 patients with shoulder dislocation revealed nerve damage not previously reported. Although axillary nerve lesions were most common, posterior cord and musculocutaneous nerve damage occurred each in five cases. The mechanism of injury was important. The most surprising patterns were associated with blunt injury or recurrent spontaneous dislocation.
