Abnormal Foramina on the Posterior Arch of the Atlas Vertebra: A Unique Anatomical Phenomenon
Author(s): Lignar Cross*
The presence of abnormal foramina on the posterior arch of the atlas vertebra is a rare but intriguing anatomical anomaly. The atlas vertebra, or C1 vertebra, plays a vital role in supporting the skull and facilitating head movement. While the posterior arch of the atlas is typically smooth, the existence of foramina in this region is a subject of fascination for anatomists and medical professionals. These foramina, small bony openings, occur in less than 1% of the population and exhibit considerable variation in size, number, and location. Their exact etiology remains uncertain, with possible links to developmental anomalies or genetic factors. While most cases are benign, rare instances of complications, such as impingement on nearby structures, underscore the need for continued research into these anomalies. This abstract highlights the uniqueness of abnormal foramina on the poster.. Read More»
