Percutaneous sacroiliac screw is one of the main methods to treat posterior pelvic ring injury. Due to the complicated pelvic anatomy, the probability of malposition of screws under conventional fluoroscopy freehand operation ranges from 2% to 15%1, 2,which may result in neurovascular complications. Meanwhile, upper sacral vertebral body(S1) dysmorphism is widely recognized and the requirement of biomechanical stability is increased, people began to explore the clinical application of second sacral vertebrae(S2) fixation.
