A 42‐year‐old woman was involved in a traffic accident in which she sustained a transtectal transverse fracture of the acetabulum. (a) Immediate anteroposterior radiograph. The arrow indicates a typical fracture disrupting the ilioischial and iliopectal lines and both lips of the acetabulum. (b) Representative section from the CT scan showing a fracture line located on the weight‐bearing dome of the acetabulum. (c) Postoperative anteroposterior radiograph. The reduction was graded as anatomical. (d) Anteroposterior radiograph obtained at the 26th month of follow‐up showing a normal appearing hip with type I heterotopic ossification (arrow).
