dc.description.abstractIntroduction: The atlas, the first cervical vertebra, supports the head. It is unique in that it fails to incorporate acentrum. Because it supports the skull, it was named after Atlas who, according to Greek mythology, supportedthe earth on his shoulders. Frequently bony spurs arise from the anterior and posterior margins of the groove forthe vertebral artery. These are sometimes referred to as Ponticles, and they occasionally convert the groove intoa foramen. More often the foramen is incomplete superiorly. Arcuate foramen also known as ponticulus posticus(Latin for “little posterior bridge”).Aims and Objectives: To study the proportion and various types of ponticuli.Materials and methods: Present study was conducted on 100 adult human atlas vertebrae, collected from thedepartment of Anatomy, Mysore Medical College and Research Institute, Mysuru.Observations and Results: Out of 100 atlas vertebrae examined, 20 atlas vertebrae showed ponticuli of varioustypes. 27 Ponticuli was observed in twenty (20) atlas vertebra as follows: a) Ponticulus posticus -15. b) Ponticuluslateralis -07. c) Ponticulus posterolateral -05. d) Complete Ponticulus -11. e) Incomplete Ponticulus -16.e) Bilateral Ponticulus -07. f) Unilateral Ponticulus -13. g) Right side -17 and Left side -10.Conclusion: Proper identification of this anomaly on preoperative lateral radiographs should alert the surgeonto avoid using the ponticulus as a starting point for a lateral mass screw in order to not injure the vertebralartery. It is also useful to surgeons who face regularly the patients complaining about the symptoms ofvertebrobasilar insufficiency like headache, vertigo, migraine.en_US
