Wackenheims line

Wackenheims line (also known as the clivus canal line or basilar line) is formed by drawing a line along the clivus and extending it inferiorly to the upper cervical canal.

Normally the tip of the dens is ventral and tangential to this line. In basilar invagination odontoid process transects this line.
