Figure A shows an APC III injury, which is a rotationally and vertically unstable injury, with damage to the anterior ring, pelvic floor, and posterior ligamentous stabilizing structures.

The referenced study by Sagi et al found that biomechanically, a percutaneous iliosacral screw and anterior ring internal fixation was the most stable construct. In addition, he found no biomechanical support for addition of a second iliosacral screw.

Biomechanical analysis of fixation for vertically unstable sacroiliac dislocations with iliosacral screws and symphyseal plating.
