ABSTRACT
Bilateral traumatic dislocation of the hip is rare and infrequently reported. Bilateral traumatic hip dislocation with an associated unilateral acetabular fracture is even rarer. A case where a 43 year old lady sustained bilateral hip dislocation associated with a right acetabular fracture when she was sitting with her left leg crossed over the right in a bus which was involved in a collision is reported. Sitting with the legs crossed somewhat locks lower limbs and the femora in a fixed position with respect to the acetabuli and perhaps enables the impact of the collision to be concentrated. Had the lower limbs not been in this "locked" position this rare injury may not have occurred. Sitting crossed legged facing the direction of travel in moving vehicles may possibly predispose to the injury.
