ObjectiveOpen reduction and internal fixation of unstable posterior pelvic ring injury provides better bony stability and less long term morbidity than nonoperative treatment. However, open reduction and internal fixation of the posterior pelvis may involve substantial intraoperative blood loss, reported infection rates of 6 to 25%, and wound complications in 25%. Our hypothesis was that percutaneous cannulated iliosacral screws placed by fluoroscopic control would provide early, rapid, definitive stabilization with minimal blood loss, infection, and wound complications.DesignA retrospective medical record and radiographic study. MATERIALS, METHODS, MEASUREMENTS AND MAIN RESULTS: Twenty consecutive patients with an unstable posterior pelvic ring injury treated by percutaneous fixation (41 screws) under fluoroscopic guidance were reviewed. Average patient age was 34 years, trauma score was 14.4 +/- 3.3, and Injury Severity Score was 22.9 +/- 10.6. Mechanisms were motor vehicle collisions (11), falls (3), crush injury (3), and pedestrian/auto (3). Pelvic injuries were classified as Tile B (5) or Tile C (15). Associated injuries were present in 80%. Seventy-five percent of patients underwent pelvic fixation less than 72 hours after injury with closed percutaneous screw placement achieved in 60%, assisted by open reduction in 25% or aided by anterior external fixation in 15%. Mean operative time was 52 minutes for patients requiring percutaneous screws only (7 of 20 patients, 35%), whereas average blood loss was 233 mL for all cases (including open anterior and posterior procedures). No loss of fixation or wound complications occurred during 9.6 months follow-up.ConclusionsPercutaneous iliosacral screw fixation for unstable posterior pelvic disruption provided early fixation with minimal operative time, minimal blood loss, and wound-related morbidity.
