case_images: When brought to the local hospital, plain radiograph showed a right posterior hip dislocation associated with a femoral head fracture (Fig. 1).

case_images: Manipulation and reduction (M and R) were attempted, approximately within 6 h to injury, to relocate the right hip and subsequent post M and R radiographs showed iatrogenic fracture of the femoral neck (Fig. 2).

case_images: An urgent computed tomographic scan was done which showed a fracture-dislocation of the right hip (Fig. 3).

case_images: The fracture line ran inferior to the fovea separating a main superior and grossly comminuted inferior fragment (Fig. 4 and 5).

case_images: The femoral head was then reduced within the acetabulum and the trochanteric flip osteotomy was fixed usingheadless and cortical screws (Fig. 6).
case_images: Plain radiograph showing avascular necrosis of the femoral head with progressive shrink and collapse.

case_images: Plain radiographs showed avascular necrosis of the femoral head with progressive shrink and collapse (Fig.7), resulting in prominent compression screws abutting against the acetabulum.
case_images: Plain radiograph post-right total hip arthroplasty.

case_images: Given the clinical picture, we counseled the patient for the removal of implants and conversion to the right total hip arthroplasty (Fig.8).The patient underwent surgery uneventfully.
