Abstract

The distinguishing characteristic of the axis vertebra is the odontoid process. The axis vertebra has a very different form from the other cervical vertebrae. Surgery for axis vertebral fractures is very risky. These fractures are rather prevalent. As such, it is essential to have a solid grasp of the anatomical diversity prior to performing the surgery. Measuring the precise morphometric parameters of the odontoid process of the axis vertebra was the goal of the current investigation. This study analyzed 50 fully ossified human axis vertebrae of unknown gender and age, using a cross‐sectional design. We measured various dimensions of the odontoid process, including its anterior height, anteroposterior (AP) diameter, maximum width, width and dens axis sagittal angle. A digital vernier caliper and conventional goniometer were used to measure different morphometry of the odontoid process. The data was collected, tabulated, and statistically analyzed using GraphPad Prism version 4.03. In our study, we found that the average height of the odontoid process of the axis vertebra was 14.81±1.17 mm, while the anteroposterior (AP) diameter was 10.05±0.88 mm. The maximum width of the odontoid process was 10.24±0.90 mm and the average width was 9.34±1.06 mm. Additionally, the dens axis sagittal angle was found to be 12.86±4.70 degrees. To help surgeons avoid and minimize complications like vertebral artery injury, cranial nerve damage and injury to other vital structures when performing any surgical or interventional procedure around the cranio‐vertebral region the present study provided us with important anatomical data on various parameters of the axis of Indian origin.
