Abstract:

Objective To study the morphology of the occipital condyles. Methods The occipital condyles were measured and classified in 165 occipital bones. The anteroposterior dimension, mediolateral dimension, the thickness and the angle between the anteroposterior axis and the medial sagittal line of the foramen magnum were measured. Results The mophology of the occipital condyles can be divided into 6 types, namely, elliptical shape in two sides, accounting for 66.1%(109 cases), dumbbell-like shape in two sides, accounting for 7.9%(13 cases), elliptical shape at the left and dumbbell-like in the right, accounting for 6.7%(11 cases), dumbbell-like at the left and elliptical at the right, accounting for 8.5%(14 cases), elliptical shape at the left and triangular shape at the right, accounting for 3.6% (6 cases) triangular shape at the left and elliptical shape at the right, accounting for 7.3% (12 cases). Conclusions The occipital condyles have more anatomical shapes than traditional description With the elliptical shape occupying the majority.
