However, PSSF is technically challenging due to the complex pelvic anatomy and surrounding neurovascular structures, requiring precise fluoroscopic guidance. Issues such as poor visualization due to body habitus, bowel gas or fecal loading can prolong surgical time, increase radiation exposure, and increase the risk of nerve injury. This randomized controlled trial aimed to evaluate the effect of preoperative bowel preparation using a cleansing enema on fluoroscopic pelvic image quality and radiation exposure during PSSF.en-USUnstable pelvic ring injurypercutaneous sacroiliac screw fixation (PSSF)fluoroscopic pelvic image quality score (FPIQS)radiation exposure (KAP)bowel preparationcleansing enemarandomized controlled trialscrew insertion timepostoperative reduction qualityneurovascular injury.Thesis
