Moreover, 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].
Similarly, 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.
Additionally, 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].
