case_images: Screw tightening is performed under fluoroscopic guidance to avoid over compression of the zone 2 sacral fracture (Figures 2(a) and 2(b)).
case_images: Intraoperative clinical photographs during definitive sacral ORIF. (a) Vertical zone 2 sacral fracture visible after irrigating and debriding the fracture site. Schantz pins attached to T-handle chucks placed in both posterior superior iliac spines are used as reduction tools. (b) Reduction of the sacral fracture maintained with a pelvic reduction forceps.

case_images: Reduction was performed using a pelvic reduction forceps placed on the spinous process and lateral ilium, and Schanz pins placed in the posterior superior iliac spines (Figures 3(a) and 3(b)).
