Case report and rehabilitative management of a complete musculocutaneous nerve injury caused by shoulder dislocation.

Abstract

Anterior shoulder dislocation can secondarily cause nerve injury and/or rotator cuff tear. An elderly male with a recent shoulder dislocation and multiple medical comorbidities was transferred to a rehabilitation inpatient service in order to maximize his functional status. Physical exam suggested a brachial plexus injury. Electrodiagnostic testing confirmed a complete musculocutaneous and a partial axillary nerve lesion. This specific combination of nerve lesions is a previously unreported complication of anterior shoulder dislocation. Prognosis and treatment are discussed, particularly the use of electrodiagnostic findings to tailor rehabilitation program design.
