C1 / Atlas


Anatomy Monday: Cervical Vertebra 1 (C1 or Atlas)

Since I showed a case of a posterior cleft of C1 last week I thought I’d follow up with some key anatomy of C1 as seen on cone beam computed tomography (CBCT) images. These are all axial views that have been rotated as such to show the entire ring on […]


Case of the Week: Posterior Cleft of Cervical Vertebra 1 (C1 or Atlas)

This week I have a developmental anomaly where the posterior arch of C1 does not completely fuse together. This can be seen best on axial views on cone beam computed tomography (CBCT). Due to the angle of the scan you won’t likely see the entire arch as I have shown […]
