(a) Oblique sagittal reformatted view of the pelvis CT scan (bone window, slice thickness 1 mm) acquired after osteosynthesis (first step of the procedure). The first screw was placed into the iliac bone from the posterior iliac crest to the anterior inferior iliac spine along the arcuate line. The cross section of the proximal part of the second screw inserted into the sacroiliac joint is visible (small arrow). (b) Oblique axial reformatted view of the pelvis CT scan after iliac screw fixation. (c) Oblique axial reformatted view of the pelvis CT scan after sacral screw fixation. This second screw was inserted into the sacroiliac joint to the sacral wing.
