Fig. 3From: Morphology analysis of the C2 pediculoisthmic component and feasibility of safe C2 pedicle screw placement: comparison of multiplanar reconstruction versus traditional radiographic methodsComparison between the transverse PIC width (TPW), oblique PIC width (OPW) and minimum PIC diameter (MPD) at the parameters of endosteal diameter, outer diameter and the ratio of ED/OD (a) and between the left and right widths of the PIC at TPW1, TPW2, OPW1, OPW2, MPD1 and MPD2 (b). Error bars show standard deviations, *P < 0.05, **P < 0.01, ****P < 0.0001Back to article page
