Simultaneous bilateral posterior dislocation of the shoulder: diagnostic problems and management. A case report.

Abstract

We present the case of a patient who sustained simultaneous bilateral posterior dislocation of the shoulder after a possible epileptic fit. The confirmation of the diagnosis was reached only by a computed tomography (CT) scan, after the clinical suspicion. Under general anesthesia, close reduction of both shoulder dislocations was done. Posterior dislocation of the shoulder-especially the bilateral one-is very rare. When the history describes an electric shock or convulsive seizure, any shoulder injury demands a careful clinical and radiological evaluation. It is usually associated with reverse Hill-Sachs lesion (an impression defect of the anteromedial aspect of the humeral head), in which the size determines the treatment options.
