Simultaneous bilateral posterior fracture-dislocation of the shoulder.

Simultaneous bilateral posterior dislocation of the shoulder complicated with a fracture (fracture-dislocation) is an extremely rare condition and the relevant literature contains very few published case reports. Besides its rarity, this complicated condition may cause delays in diagnosis because of the physicians’ tendency to use plain radiography which is known to have low sensitivity in detecting concomitant fractures. This report describes a successfully treated case of simultaneous bilateral fracture-dislocation of the shoulder which could be clarified by computed tomography (CT) performed following a failed reduction of the shoulders. In conclusion, physicians should consider this rare entity and if there is a doubt CT should be performed for accurate diagnosis.
