Obturator hip dislocations with an associated osteochondral fracture of the femoral head are uncommon. The treatment of these injuries is challenging and the functional outcomes are poor. This case report illustrates a novel technique for fixation and stabilization for an unusual injury involving an obturator hip dislocation and an osteochondral impaction fracture of the femoral head. A 30-year-old African American male, involved in a motor vehicle collision, sustained an obturator dislocation of the left hip with a large posterior osteochondral fracture of the femoral head. An emergency closed reduction procedure was performed followed by a computed tomography (CT) scan of the hip joint which demonstrated a large osteochondral defect (25 x 10 mm, Depth: 5 mm) of the femoral head, visualized within the weight-bearing area. Surgical intervention was planned as a fracture of the femoral head with a defect deeper than four millimeters has been shown to be a risk factor for the development of post-traumatic arthritis, often with the onset of symptoms within 5 years of the date of injury.
