Figure 8 :Sagittal (cranial-caudal) and transverse (medial-lateral) angles for pedicle screw placement in the thoracolumbar and sacral spine. The transverse angle is calculated with basis on pedicle’s angle and the midline. The sagittal angle is calculated with basis in the pedicle’s angle and a line parallel to the ground.
