Axis is the second cervical vertebra which is atypical. Dens or odontoid process of the axis forms the median atlantoaxial joint and also gives attachment to apical and alar ligaments. Apical ligament of dens is the remnant of embryologic notochord which may sometimes calcify causing compression, pain and restriction of neck movements as seen in crowned dens syndrome. 68 dried cervical vertebrae have been observed after excluding broken ones. 24 Atlas and axis vertebrae were examined where one axis showed a prominent dens. Morphometric measurements recorded with vernier calipers were 24.2 X 10.4 X 11.1 mms. The present study showed lengthier dens when compared with other studies. Etiology of crowned dens syndrome should be suspected in such cases. The apical ligament may be calcified at its attachment with the dens contributing to the lengthy odontoid process. Calcified apical ligament due to granular deposition gives crown like appearance of the crowned dens syndrome which commonly affects aged individuals. The present study reports an abnormal dens of the axis vertebra which may be due to crowned dens syndrome.
