a) Pre operative AP radiograph; Preoperative radiograph clearly showing the anterior dislocation of the hip, disruption of anterior column of the acetabulum and the ischial ramus fracture; b) CT image, 3D CT image depicting the position of the femoral head. Note that there is no bony obstacle to reduction; c) Post operative radiograph, Post operative anteroposterior radiograph showing concentric hip reduction and accurate reduction and fixation of the fracture with a 10 hole 3.5 mm reconstruction plate

The radiographs showed a superior type of dislocation hip with break in the iliopectineal line and fracture of the ischial ramus (Figure 1 (a)). No bony obstruction to reduction could be identified on CT images (Figure 1 (b)). The postoperative radiographs showed concentric reduction of the hip with accurate reduction of the fracture (Figure 1 (c)).
a) Intraoperative image, Intraoperative image showing the completely intact articular surface of the femoral head; b)Twin incision, the twin incision technique as used. Note the intervening skin bridge is the vascular supply zone of the circumflex iliac arteries
