Percutaneous Ilio-sacral Screw Fixation for Unstable Pelvic Ring Injuries

This prospective interventional study was planned to determine the clinical and radiological outcome of percutaneous iliosacral screw fixation for unstable pelvic ring injuries. It was conducted from March 2008 to June 2014 at the Department of Orthopaedic Surgery Combined Military Hospital (CMH) at Lahore, Multan, Rawalpindi and Muzaffarabad. It comprised 50 patients with unstable pelvic ring injuries. Visual analogue scale (VAS), Majeed pelvic score and Lindahl criteria were used for functional and radiological outcomes assessment. The mean age of the patients was 47.82±8.94 years. Moreover, 33(66%) participants were males and 17(34%) were females. The mean pre-operative Majeed and VAS scores were 38.98±6.28 and 9.04±0.67, respectively. Operating time and blood loss were reduced significantly. VAS score for post-operative pain was 3.82±1.26 at 1 month and decreased further to 2.68±1.30 at 12 months post-operatively (p<0.001). Radiological outcome and the post-operative Majeed scores were good to excellent in 43(86%) cases. Thus Percutaneous iliosacral screw fixation of unstable pelvic ring injuries resulted in excellent radiological and functional outcome with significantly decreased post-operative VAS score for SI joint pain.
