Exemplarily preoperative, intraoperative and postoperative radiographs of a patient treated by MIS ISS placement guided by navigation for a traumatic fracture of the sacrum. A and B shows the preoperative CT scan (A in frontal view, B in axial view). C and D shows p.a. (C) and lateral (D) intraoperative radiographs after the ISS placement guided by navigation with the guide wire still in situ. E–G shows screw positioning in the postoperative CT scan (E in sagittal, F in frontal view and G in axial view)
