Accordingly, what causes Ponticulus Posticus?
The ponticulus posticus is a bony bridge in the first cervical vertebra between the lateral mass and the posterior arch. It results due to ossification of the posterior atlanto-occipital ligament of atlas and encloses the vertebral artery and the first cervical nerve root [6].
Also, what is a posterior Ponticle? A complete posticus ponticus is one continuous bridge that extends from the posterior aspect of the lateral mass to the anterior aspect of the posterior tubercle. A partial lower posticus ponticus is one that extends partway from the posterior tubercle toward, but not touching, the posterior aspect of the lateral mass.
Herein, what is Kimmerle anomaly?
The Kimmerle anomaly is an anatomical variant of the atlas that results in obstruction of the vertebral artery by an osseous ponticle or a calcified ligament.
