case_images: It showed that the femoral head-neck junction was entrapped through the hiatus created by the medially displaced quadrilateral surface between the anterior and posterior columns (Figure 2).

case_images: Immediate post-op AP pelvis X-ray showed adequate reduction and fixation of the fracture dislocation (Figure 3).
case_images: Medial displacement of both the quadrilateral surface and femoral head resulting in focal joint space narrowing at the superomedial joint surface.

case_images: Anteroposterior radiographs of the pelvis and lateral radiographs of the hip were obtained and showed a millimetric medial displacement of both the quadrilateral surface and femoral head resulting in focal joint space narrowing at the superomedial joint surface (Figure 4).
case_images: Terminal right hip osteoarthritis.

case_images: On follow-up radiographs, the patient was found to have progression of joint degeneration till reaching, after two years, a severely degenerated joint with joint space narrowing and femoral head sclerosis with possible avascular necrosis (Figure 5).
