Abstract
Objectives: The aim of the present study was to know the incidence of double foramen transversarium (FT) in the dried cervical vertebrae and its clinical importance. Materials and Methods: A total number of 150 dried cervical vertebrae were collected from the department of anatomy to investigate the presence of double FT. The occurrence of double foramina was observed on both sides of the same vertebrae. Results: In the present study out of 150 cervical vertebrae, double FT was observed in 33 (22.00%) vertebrae among them double foramen seen unilaterally in 16 (10.67%) vertebrae and bilaterally in 17 (11.33%) vertebra. Conclusion: In the present study, bilateral double FT was found to be more common than unilateral, contrary to the findings as mentioned in most of the previous similar studies. This anatomical knowledge is clinically important since the course of the vertebral artery may be distorted in such situations and may result in certain clinical conditions like posterior headache, migraine, fainting attack, etc. This study may be useful to neurosurgeons and radiologists.
