The Cervical Intervertebral Foramen: Microanatomy, Pathology, and Clinical Implications

Area of Science:

• Spine anatomy and biomechanics
• Interventional pain management
• Neurosurgery

Background:

• The cervical intervertebral foramen (cIVF) is a complex anatomical corridor for cervical nerve roots.
• Degenerative changes like facet hypertrophy and disc herniations can compromise the cIVF, leading to nerve root compression and cervical radiculopathy.

Purpose of the Study:

• To provide a comprehensive primer on cervical intervertebral foramen (cIVF) anatomy.
• To aid spine surgeons, interventionalists, and physiatrists in treating cervical spine pathology.
• To encourage further research into cIVF microanatomy.

Main Methods:

• Evidence-based narrative review of existing literature.
• Synthesis of key imaging, cadaveric, and clinical studies.
• Focus on the microanatomical structures within the cIVF.

Main Results:

• Exploration of dynamic changes affecting foraminal size and nerve root compression.
• Detailed analysis of the dorsal root ganglion's relationship to the cIVF.
• Discussion of the function and clinical significance of foraminal ligaments, arteries, and veins.

Conclusions:

• Alterations in the cIVF are a common basis for cervical degenerative pathologies.
• A thorough understanding of cIVF microanatomy enhances the treatment of underlying disease processes.
• Improved anatomical knowledge facilitates better patient outcomes for cervical radiculopathy.
