Abstract               Background: Axis vertebra (C2) is atypical in its shape and morphological characteristics and forms an integral part of the craniovertebral junction Aims and Objectives: Study of measurement of unpaired and paired parameters of axis vertebra in males. Methodology: This was a cross-sectional study carried out in the apparently normal individuals undergone MRI for neck included into the study over a six month period i.e. January 2018 to June 2018 in the six month period 50 males were included into study. We have done morphometric analysis of Axis Vertebra with respect to Body Axis – AP and Transverse diameter, Ant. height, Post. Height; Dense of axis –AP, Transverse diameter, Vertical height; Vertebral canal–AP and Transverse diameter etc. The paired parameters like Pedicle, Superior articular facet, Inferior articular facet, Lateral mass, Foramina transversarium, Lamina etc. was measured and data entered excel sheets and analyzed by excel software for windows. Result: In our study we have found in males the Body of Axis the Mean±SD in mm - AP diameter was -13.2± 0.42; Transverse was 17.96±0.87; Ant. height was 9.64± 0.38; Post. Height was 9.06± 0.56. In Dense axis it was, AP diameter -7.61 ±0.19, Transverse- 7.60 ± 0.20; Vertical-15.79 ± 0.87; Vertebral canal – AP Was 12.40 ± 0.55, Transverse was 18.64 ± 0.77. The measurement on Lt. and Rt. Respectively of Pedicle -Length was 27.98± 4.12 and 27.87± 3.45 Width was 6.98± 2.87 and 6.54± 3.12 ; Height was 8.78±2.61 and 8.74 ± 3.42 ; Median angle -8.12±1.32 and 8.18± 3.42; Superior articular facet AP-diameter was 16.21±1.65 and 16.31±1.81; Trans. Diameter was 14.63±2.13 and 14.42±1.45; Superior angle of SAF was 78.81±4.35O and 78.62±3.75. Conclusion: It can be concluded from our study that parameters of Axis vertebra on unpaired and paired i.e. Rt. and Lt. side is definitely useful for the diagnosis, surgical management and understanding the pathology cervical neck etc.
