ABSTRACT
Background & Objective: The foramen transversarium in the transverse process is the characteristic feature for cervical vertebrae and distinguish it from other vertebrae. It transmits the vertebral artery, vertebral vein and sympathetic nerves. These foramina show variations in its size, shape and number. The present study was done to find out the incidence of accessory foramen transversarium and compare it with other study. Methodology: A total 150 dried cervical vertebrae were observed macroscopically for accessory foramen transversarium in the department of anatomy. Results: Out of 150 vertebrae, accessory foramen transversarium was found in 41(27.33%) vertebrae. Among 41 vertebrae unilateral accessory foramen transversarium was found in 27(18%) vertebrae and bilateral was found in 14(9.33%) vertebrae. Conclusion: The knowledge of accessory foramen transversarium is useful for spine surgeons in surgery around cervical vertebrae. It helps radiologists in interpretation of computed tomogram and magnetic resonance image scans. It is also helpful for anatomist, anthropologist and clinicians.
