Non-operative treatment of neglected bilateral posterior four-part fracture- dislocation of the shoulders--a case report.

BACKGROUND: Bilateral posterior dislocation of the shoulders is rare and may result from a seizure. A 48 year-old HIV-positive man who presented eight weeks after bilateral posterior shoulder dislocation and bilateral fractures of the surgical necks of both humeri is reviewed. He was treated with an algesics and physiotherapy and was able to return to work after 9 months. CONCLUSION: The rarity of this lesion, its late presentation, the importance of a high index of suspicion in making the diagnosis and the fair outcome of non-operative treatment informed this report.
