|Bone: Clivus (anatomy)|
|Superior view of the clivus|
|Longitudinal section of the head and neck showing the anatomical relation of the dens (labeled odontoid process of axis) and clivus (not labeled).|
|Gray's||subject #35 148|
Behind the dorsum sellæ is a shallow depression, the clivus, which slopes obliquely backward, and is continuous with the groove on the basilar portion of the occipital bone; it supports the upper part of the pons.
Relation of the clivus and dens
The clivus is an important landmark for checking for anatomical atlanto-occipital alignment; the clivus, when viewed on a lateral C-spine X-ray, forms a line which, if extended, is known as the known as Wackenheim's clivus line. Wackenheim's clivus line should pass through the dens of the axis or be tangential to it.
