The rotation and fixation of acetabular fragments. A Place the Schanz nail between the upper and lower anterior superior iliac spine and hold it with a T handle. B The reduction towel clip was clamped at the pubic branch osteotomy end and the ilium osteotomy end respectively, so as to cooperate with the T handle to complete the rotation coverage, including rotate clockwise when looking down vertically (a), lifting, pressing down and turning inversion (b). C The fragments were fixed with stainless steel screws (Zimmer, 3.5-mm screw diameter and 2–5 cm length for fixation of anterior superior iliac spine, 4.5-mm screw diameter and 5–13 cm length for the others), triangular support and fixation as much as possible, and finally fix the bone block of sartorius muscle stop
