Proximal Median Neuropathy Following Anterior Shoulder Dislocation: The Use of Magnetic Resonance Neurography.

Proximal median nerve injury is an uncommon consequence of anterior shoulder dislocation, especially occurring in isolation of other upper limb peripheral nerve injury. We report the case of an 82-year-old woman with a median nerve injury as detected by clinical and neurophysiological examination following a fall and anterior shoulder dislocation. Magnetic resonance neurography confirmed the diagnosis, but also detected asymptomatic brachial plexus and ulnar nerve involvement. Management was non-operative and there has been some improvement over several months. Our case expands the differential diagnosis for proximal median neuropathy and discusses the utility of neurography in cases of neural injury.
