The axis is the second cervical vertebra and differs from the others by presenting particular anatomical landmarks. Morphological variations of the axis in different populations have clinical importance, since the lack of anatomical reference may compromise surgical procedures in this region. Objective: To analyze the morphometry of axis vertebra in northeastern Brazil. Methodology: Data collection was performed at the Federal University of Paraiba. Fifty-eight axis were used. Damaged or infantile vertebrae were excluded.Morphometric analysis was performed using a digital caliper and the data were statistically analyzed. Results were considered significant when p<0.05. Results: The width of the pars interarticulares was 9.25±1.68mm and the height was 7.37±1.87mm. The height of the dens of the axis in an anterior view was 16.29±1.82mm and the width was 9.41±0.86mm. The width of the articular face of the dens was 8.27±0.88mm. The anteroposterior length of the vertebral body was 15.29±2.02mm, the width was 16.79±1.68mm, and the height in anterior view was 19.96±2.48mm. The mean height of the vertebral lamina was 10.89±1.64mm and the anteroposterior length was 20.33±2.13mm. Significant difference was observed between right and left sides of anteroposterior length (p=0.012). Conclusion: Axis morphometry was shown for the first time in a specific population from northeastern Brazil. Morphological differences were observed in the present study and differ from others in the literature. These data may serve as guidance for professionals who will perform any procedures in this region, highlighting the importance of anatomical knowledge and its variations.
