Abstract :

Morphometric Evaluation of Anterior Aspect of Atlas and Axis Background: Median atlanto–axial joint dislocation and fracture of dens may require the surgical decompression by anterior approach in certain cases. Aim and objective: To evaluate the dimensions of anterior part of atlas and axis verteae quantitatively and discuss its clinical importance. Material and Methods: Morphometric measurements were done for forty atlas (thickness, transverse distance, height of anterior arch) and forty axis verteae (odontoid height, widest odontoid diameter in coronal plane, height and width of facet on dens). Mean, standard deviation, standard error and 95% confidence interval were calculated for each parameter. Results: The mean anterior arch thickness and height were 5.81 +/– 1.19 mm and 11.45+/–2.79 mm respectively. The distance between medial margins of lateral masses was 15.58 +/– 2.75mm. The height and widest odontoid diameter were 15.26+/–2.51mm and 10.68+/– 0.78 mm respectively. Conclusions: Our study provides the useful data on dimensions of atlas and axis for anterior approach surgery at c1–c2 junction.
