Besides, 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].
One may also ask, 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.
Hereof, what is Ponticulus Posticus?
(Left) Unilateral partial ponticulus posticus. Ponticulus posticus, which means “little posterior bridge” in Latin, is actually a bony prominence arising from the posterior arch or the superior articulating process of the atlas that completely or partially encircles the vertebral artery [1].
