AI Article Synopsis

  • The foramen transversarium, located in the cervical vertebrae, is crucial for the passage of essential neurovascular structures, and abnormal ossifications in this area can lead to serious clinical issues.
  • A study evaluating 182 dried cervical vertebrae and 190 patients with neck-related problems found various types of abnormal ossifications, including accessory foramina and stenosis.
  • Notably, some patients experienced severe conditions like cervical kyphosis and spinal canal stenosis due to these changes, highlighting the importance of recognizing these ossifications for effective diagnosis and management in spinal disorders.

Article Abstract

Background: The foramen transversarium is a vital anatomical structure found in the cervical vertebrae of the spine. Typically, it serves as a passageway for important neurovascular structures, including the vertebral artery and vein, as well as the vertebral nerve. However, abnormal calcification or ossification of soft tissues in and around this area can lead to various clinical implications. Understanding the presence and implications of abnormal ossified structures in and around the foramen transversarium is crucial for clinicians involved in the diagnosis and management of cervical spine disorders.

Aims: Accordingly, this present study was designed to evaluate the abnormal ossified structures anatomically and radiologically within and around the foramen transversarium.

Materials And Methods: This study was conducted on 182 (26 sets of cervical vertebrae) dried human cervical vertebrae obtained from the respective departments of anatomy and on 190 (95 males and 95 females) adult patients who visited the radiology department for neck-related problems such as stiff neck, neck/shoulder pain, dizziness, vertigo, imbalance, visual disturbances, and cognitive impairment.

Results: Among 182 examined cervical vertebrae, unilateral complete accessory foramen transversarium was found in 23 vertebrae (12.63%), bilateral complete in 19 (10.44%), bilateral incomplete in 6 (3.29%), unilateral complete double in 4 (2.19%), and unilateral complete absence of foramen transversarium in 3 (1.64%). Stenosis due to aberrant osteophytes was noted in 9 vertebrae (4.9%). Out of 190 patients, three males presented with cervical kyphosis, severe spinal canal stenosis, and spinal cord compression due to ossification of the posterior longitudinal ligament and osteophyte complexes at C3-C6, with the most significant compression at C5-C6.

Conclusion: A thorough understanding of abnormal ossifications in and around the foramen transversarium is crucial for the management of cervical spine disorders; imaging modalities such as X-ray, computed tomography, and magnetic resonance imaging are crucial for recognizing and intervening in these cases, which is essential to prevent adverse neurological outcomes associated with vertebral artery involvement.
