Late complication of Acetabular fracture

Avascular necrosis - osteonecrosis of the femoral head may occur even if the hip is not fully dislocated. The condition is probably overdiagnosed because of an erroneous interpretation of x-ray appearance following impacted marginal fractures of the acetabulum. Other complications : *iliofemoral venous thrombosis *sciatic nerve injury *heterotopic bone formation *loss of joint movement & secondary osteoarthritis
