CT-guided iliosacral screw placement

摘要

Computed tomography (CT)-guided iliosacral screw placement for posttraumatic instability of that joint is a safe procedure that may be performed in a radiology department. CT guidance allows more accurate screw placement than traditional fluoroscopic imaging in the operating room. This article describes the technique for placing cannulated surgical screws percutaneously across the iliosacral joint in patients with unstable pelvic fractures using CT for guidance. We also discuss the pitfalls of the procedure and the complications.
