Which Technique Should Be Choosed in Posterior Pelvic Ring Injuries: Percutaneous Sacroiliac Screw Fixation Technique or Posterior Percutaneous Transiliac Plating Technique?

Objective: Besides the difficulties in both the diagnosis and treatment of sacral fractures, there exists controversy for choosing surgical procedure. The aim of our study is to compare the applicability and the postoperative results of percutaneous sacroiliac screw fixation technique and posterior percutaneous transiliac plating technique, which are the commonly used techniques in our clinic. Material and Method: A total of 29 patients who were operated for unstable posterior pelvic ring injury in Mugla S？tk？ Ko？man University Medical Faculty Hospital between May 2013 and June 2018 with a minimum follow-up of 6 months were included in the study. Patient data/radiographs were reviewed for patient demographics, type of the trauma, duration of surgery, operative time, number of intraoperative fluoroscopic imaging, postoperative complications. After the 8th postoperative week, full weight bearing was permitted to the patients. Pelvic outcome score was evaluated at the 3rd month postoperatively. Results: There was no significant difference between Pelvic Outcome Score and fixation types (p>1.0). There was no significant difference between gender and Pelvic Outcome Score (p>1.0). There was no significant difference between age and Pelvic Outcome Score (p=0.056). The mean duration of surgery was 35.3 minutes in patients who underwent posterior percutaneous transiliac plating, and 48.56 minutes (32-67 min) in patients who had percutaneous sacroiliac screw fixation (p<0.001). When the number of introperative fluoroscopy imaging was evaluated, it was found that the average number of imaging was 2.46 and 37.3 in the posterior percutaneous transiliac plating technique and percutaneous sacroiliac screw fixation technique, respectively (p<0.001). Conclusion: Treatment results were similar with both methods. In patients with posterior percutaneous transiliac plate fixation, duration of surgery is shorter and the exposure to the fluoroscopy is quite low
