Figure 1 :Technique of measuring the pedicle width and the axis length in the axial CT image before planning screw insertion. The pedicle width (red line) is measured at its narrowest part between the two cortices. The pedicle axis length (blue line) is measured along its axis from the lateral mass till the anterior vertebral body
