Abstract
Unstable pelvic ring injuries require definite operative fixation. While the posterior ring can be fixed utilizing open approaches, percutaneous screw fixation has become the treatment of choice avoiding the complications of open approaches. As the pelvis is a complex three-dimensional (3D) shape with many neurovascular structures situated within it, a thorough knowledge and understanding of the anatomy and radiographic imaging is required to accomplish the task of percutaneous iliosacral screw placement, while avoiding potential complications. Recent advances in computer assisted surgery (CAS) has provided some powerful tools in overcoming the obstacles associated with this procedure. This review examines the evolution of image guided surgery used for iliosacral screw placement, the current available options, and future perspectives.
