Técnica quirúrgica para facilitar la colocación de tornillos sacroilíacos percutáneos

Percutaneous iliosacral screw fi xation Percutaneous iliosacral screw fi xation is a useful technique for fi xation ofposterior pelvis ring injuries but it has potential complications.We describe a surgical technique modifi cation of the original technique described by Routt et al. Using the surface of the C-arm as a guide in the inlet and outlet views, exact positioning of the guide wire is easier and surgical time as radiation exposure are decreased. We hope that this modifi cation, in addition to a better understanding of sacral anatomical variations and risk factors for misplacement of iliosacral screws would reduce complications related to this procedure.
