Abstract Background The sacrum is the mechanical nucleus of the axial skeleton, located at the base of the lumbar spine and acts as the keystone at the centre of the pelvic ring. Traumatic sacral fractures are an increasingly recognized diagnosis. Sacral fractures remain a relative uncommon entity in the general population. Objective The aim of this work is to compare between percutaneous iliosacral screw and ilioilial fixation in sacral fractures fixation as regard operative time, need of intraoperative fluoroscopy, blood loss & related transfusion, infection, neurovascular complication, hardware failure and screws miss- displacement, clinical and radiological outcomes, revision rate and rate of non-union. Patients and Methods After obtaining the hospitals Research/Ethics Committee approval and written informed consents from the patients. This study was carried on 51 Patients with sacral fractures injuries through the period from August 2019 to November 2021. A prospective randomized controlled clinical trial was conducted to compare the functional and radiological outcome of closed reduction and percutaneous fixation of traumatic sacral fractures using iliosacral screw or ilioilial fixator. Results There is no statistically significant difference in functional outcome, radiological outcome operative time, blood loss, postoperative complication, union rate or follow up. There is statistically significant difference in incision length between the two groups as mean length of incision in iliosacral screw and Ilioilial fixator is 1.2 cm and 4.8 cm respectively. There is statistically significant relation between number of intraoperative fluoroscopic and fixation principles (P value <0.001) with higher risk for radiation exposure in IS screw group. Conclusion Iliosacral screw and ilioilial fixator have comparable functional and radiological outcome and similar biomechanical stability .We suggest the ilioilial fixator as an alternative to IS screw in sacral fracture management. The ilioilial fixator is a useful option in patients who do not qualify for IS screw fixation.
