An unusual case of traumatic bilateral hip dislocation without fracture.

Bilateral traumatic hip dislocations are extremely rare. Most of these are related to acetabular or proximal femoral fractures, consisting of complex lesions, and are rarely pure ligamentous injuries. Posterior dislocation is the most frequent. Some dislocations are accompanied by sciatic nerve palsy. The present case is a posterior bilateral hip dislocation with no other associated lesions, there are very few reports published with this clinical setting. The patient had good functional outcome.
