Morphometeric study of dens and its clinical importance

Background The axis vertebra's distinguishing characteristic is the existence of the odontoid process. The axis vertebra's morphology is very different from the morphologies of the other cervical vertebrae. Surgery on the axis vertebrae is exceedingly risky, and dens of axis vertebrae fractures are fairly common. As a result, it is essential to have a good grasp of the anatomical variance before performing the procedure. The study aimed to evaluate the morphometric parameters of the odontoid process of the axis vertebra. The different anatomical parameters of the odontoid process of the vertebra will be measured and compared with the previously studied parameters.

Methods Thirty dried human axis vertebrae of unknown sex will be taken. The linear and angular morphometric measurements of odontoid process will be recorded by using vernier caliper and goniometer.

Results The mean height, a-p diameter, and minimum and maximum width were 15.8mm, 10.7mm, 10.3mm and 8.5mm respectively. The total height and vertical angle were 38.1mm and 52.2 degrees respectively.

Conclusions To prevent damage to vital components and to help treat dens fractures, the information gleaned from this study may be helpful to surgeons working around the dens of the axis vertebra.
