ABSTRACT
To find the incidence of accessory foramen transversarium in dried cervical vertebrae. 150 dried cervicalvertebrae were collected from Postgraduate department of Anatomy Government Medical College Jammuand examined for the accessory foramen transversarium.Out of 150 cervical vertebrae, only 24 hadaccessory foramen transversarium with preponderance in sixth cervical vertebrae. Amongst the vertebraewith accessory foramen transversarium, 14 were bilateral and 10 were unilateral. In the present study theincidence of accessory foramen transversarium was 16%. This is important for Radiologists to interpretComputed Tomography Images and Magnetic Resonance Imaging of cervical spine.
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.
ABSTRACT
Introduction: Foramen transversaria are located on transverse processes of each cervical vertebra and transmit the vertebral artery, vertebral vein, and sympathetic nerves. These foramina are known to exhibit variations in size, shape and numbers and may be absent, incomplete or duplicate, which may lead to various symptoms. Their etiology is related with the variations in the course of vertebral artery due to developmental reasons. Objective: The present study was conducted to find the incidence of accessory foramina transversaria in the cervical spine.The recognition of these variations provide accurate and safety for the posterior surgical approaches of the cervical spine. Methodology: 210 dry cervical vertebrae of both sexes were studied in the Department of Anatomy, GCS Medical College, Ahmedabad. During our study we excluded all broken, damaged cervical vertebrae and observed the variations of foramen transversarium both in right and left transverse process of each cervical vertebra. Result: Variations in foramina were found unilaterally as well as bilaterally. 34 (16.19%) out of total 210 vertebrae studied presented accessory foramen transversarium. Conclusion: Variations in foramina may indicate, the variation in course of vertebral artery.The present study has important clinical implications for head and neck and vascular surgeons and radiologists
