Current preoperative planning. The surgical margin was designed based on the images after neoadjuvant chemotherapy. Then, size of ready-made total sacral endoprosthesis was selected accordingly. The surgical jig was designed with osteotomy planes being matched to bilateral surfaces of prosthesis precisely. Anatomical contour of the posterior iliac spine was used as the placement reference of the jig intraoperatively.
