CS: cannulated screw; exfix: external fixator; EBL: estimated blood loss; min: minutes; TITS: transiliac–transsacral screw; FU: follow-up. During the operation, the SEP amplitude on the injured side was lower than that on the contralateral side. ^#The patient had a spontaneous burst of EMG activity when the guidewire was inserted.
