Traumatic inferior hip dislocation in an adult with ipsilateral trochanteric fracture.

Traumatic Inferior dislocation of hip in adult is an extremely rare occurrence. We report a case of an inferior hip dislocation associated with an intertrochanteric fracture. Treatment consisted of an initial closed manipulative reduction of the dislocation with the aid of a Schanz screw inserted in a T handle universal chuck and using C-arm imaging. A dynamic hip screw was then used to fix the intertrochanteric fracture. At 2.5 years after the injury, the patient has symmetrical range of motion versus his contra lateral normal hip. Radiographs of the hip show normal anatomy without signs of avascular necrosis of the femoral head. To our knowledge, this is the first reported case of an adult with an inferior hip dislocation with a trochanteric fracture.
