A new approach for percutaneous ilio-sacral screw fixation: CT-based pre-operative planning with conventional fluoroscopy to reduce malposition rate and operating time

Percutaneous ilio-sacral screw (ISS) insertion using conventional C-arm fluoroscopy has been a widely employed technique for pelvic posterior ring fixation, particularly in developing regions. However, this approach presents technical challenges, leading to a high malposition rate. We introduced a new method for ISS insertion without additional equipment or software and suggested whether it could reduce the malposition rate and operating time.
