Traumatic hip dislocations with associated posterior wall fractures in children are injuries that can result in severe morbidity if not recognized and treated appropriately. Open reduction and internal fixation is recommended if the hip remains unstable after relocation or if there is significant incongruity of the articular surface of the hip after reduction. Hearty et al. recently published two cases of a posterior wall fracture in a skeletally immature patient showing how plain radiographs and CT scans were inadequate in determining the extent of the injury and that MRI was a much more reliable indication of what was seen at surgery [1].

In this case report, we describe an unusual case of a skeletally immature patient who sustained a traumatic hip dislocation with an associated posterior wall fracture. With similarity to the experience already reported [1], both CT and plain x-ray imaging failed to completely illustrate the joint injury.
