TREATMENT OF POSTERIOR PELVIC RING FRACTURE WITH SPINAL INSTRUMENTATION SYSTEM

IntroductionSacral fractures were previously treated with transiliac bars, sacroiliac screws or posterior plates. Sacroiliac screws are not as invasive, but the risk of intra-operative neurovascular damage must be considered. Posterior plate fixation is slightly invasive. In 2006, we conceived a new fixation method with spinal instrumentation system, and I will introduce it.ProcedureWe make 5cm skin incisions just above each side of post. sup. spine of ilium and make a tunnel under the soft tissue. Then, we insert 4 screws to ilium, pass two rods through the tunnel and fix them. If needed we make reduction or compression. Finally, set the transvers connecting device on both sides.Material and MethodWe indicate this method for type C1 and C2 sacral fracture on AO classification. We treated 17 cases, C1 for 6 and C2 for 11 cases. We evaluated clinically and radiologically.ResultMean operating time was 105 minutes, and mean hemorrhage was 125ml. We had 2 miss-directional insertions of screws out of 68 screws...
