a–c X-rays of Case no. 1, who was involved in a traffic accident resulting in a right T-shaped acetabular fracture; d–g the free fragment of “square zone” and low level posterior column fracture line were demonstrated in three-dimensional reconstruction radiograph; h preoperative design of the placement of oblique-ilioischial plate; i reduction and fixation were performed with the oblique-ilioischial plate through a single modified Stoppa approach. Postoperative radiographs of the pelvis (anteroposterior) j, obturator oblique k, and iliac crest oblique l showed a satisfactory reduction of the fracture, and computed tomography images showed a good anatomic reduction of the fracture m, n. The three-dimensional reconstruction shows the location of the implant o–q. Photographs at 9-months postoperatively show that satisfactory hip function was achieved
