Bilateral Traumatic Symmetric Posterior Hip Dislocation in a Teenager

Abstract

Traumatic hip dislocation is rare in children, accounting for 2 to 5% of all traumatic dislocations. Bilateral hip dislocations are unusual. There is no consensus on the protocol after reduction. We report the case of a 14-yearold girl sustaining a bilateral posterior hip dislocation after a road traffic accident in a limited resource setting. The concentrically reduction was performed 22 hours after the admission. Post-reduction radiograph showed an intraarticular fragment in the left hip and CT scan prescribed has not been performed. The patient was kept on bilateral skin traction for 3 weeks. At the end of the period of traction, bilateral hip spica cast was applied for 3 weeks. At 4 years 11 months follow-up the hips were pain-free. CT scan showed osteoarthritis secondary to AVN of the femoral head on the right hip.
