Simultaneous asymmetric bilateral traumatic hip dislocation.

A 25-year-old man presented to the emergency department with simultaneous right anterior and left posterior hip dislocations resulting from a motor vehicle accident. Simultaneous bilateral traumatic hip dislocation is an uncommon occurrence. More rare is asymmetric simultaneous bilateral hip dislocation, with only ten cases documented in the English-language literature. The importance of an anteroposterior pelvic radiograph after significant major trauma is emphasized. Several serious complications can be associated with this condition, so expeditious management in the ED is warranted.
