[Unrecognized posterior dislocations of the shoulder. Apropos of 6 cases]

Reporting six cases of posterior dislocation of the shoulder examined in a rheumatological setting, the authors emphasize the diagnostic difficulties in this condition. The post-epileptic aetiology is often unrecognized. Certain radiological techniques permit recognition of the dislocation, when the antero-posterior film shows little abnormal. The authors analyze the anatomical lesions, which sometimes include fracture, and review the orthopaedic and surgical treatments, and the results obtained.
