Cervical anterolisthesis at C5–C6 happens when the C5 vertebra slips forward over C6, disrupting normal alignment in the neck. This forward shift can pinch nerves or compress the spinal cord, causing pain, stiffness, or weakness in the shoulders, arms, or hands. RadiopaediaMedical News Today


Anatomy of the C5–C6 Segment

Structure & Location

  • Vertebral Bodies & Facets: C5 sits just above C6 in the middle of the neck. Each has a drum-shaped body up front and paired facet joints at the back, guiding movement and bearing load.

  • Transverse Foramina: Tiny holes on each side of C5 and C6 let the vertebral arteries pass to supply the brain. TeachMeAnatomy

Muscle Origins & Insertions

Several neck muscles anchor on C5–C6, stabilizing and moving your head:

  • Scalenes: Originate on transverse processes of C3–C6; insert on ribs 1–2 to bend and rotate the neck.

  • Longus Colli: Originates on bodies of T1–C5; inserts on anterior C1–C3 to flex the neck and maintain posture. Wikipedia

Blood Supply

  • Vertebral Arteries: Branch from the subclavian arteries, ascend through transverse foramina of C1–C6 and feed the upper spinal cord and brainstem.

  • Radicular Arteries: Small branches from vertebral and ascending cervical arteries supply the vertebral bodies and nearby ligaments. Kenhub

Nerve Supply

  • C5 & C6 Nerve Roots: Exit above their respective vertebrae through intervertebral foramina, join to form the upper trunk of the brachial plexus, and send motor signals to shoulder and arm muscles. Sensory fibers relay touch and pain from the outer shoulder and lateral arm. NCBI

Key Functions

  1. Head Support: Bears weight of the skull.

  2. Flexion/Extension: Allows nodding and looking up/down.

  3. Rotation: Turns head side to side.

  4. Lateral Bending: Tilts head toward shoulders.

  5. Protection: Shields the spinal cord passing through the vertebral canal.

  6. Load Transmission: Passes forces between head and torso. Cleveland Clinic


Types of Cervical Anterolisthesis

  1. Degenerative: Age-related wear of facets and discs.

  2. Isthmic: Fatigue fracture (spondylolysis) of the neural arch.

  3. Traumatic: High-force injury fracturing posterior elements.

  4. Pathologic: Bone weakened by infection or cancer.

  5. Post-surgical (Iatrogenic): Following cervical spine surgery. Wikipedia

When to See a Doctor

Seek medical care if you experience:

  • Severe or worsening neck pain

  • Radiating arm weakness or numbness

  • Difficulty walking or balance issues

  • Loss of bladder or bowel control (medical emergency)

  • Pain that isn’t relieved by rest or simple treatments


Frequently Asked Questions

QA
1. What grade is mild C5–C6 anterolisthesis?Grade I (0–25% forward slip).
2. Can physical therapy fix anterolisthesis?It can strengthen stabilizers and relieve symptoms but won’t reverse slippage.
3. Is surgery always needed?No—most cases respond to conservative care unless there’s severe spinal cord compression.
4. How long for recovery after ACDF?Typically 3–6 months to fuse fully; many resume light activity within 4–6 weeks.
5. Does an artificial disc last?Modern discs can last 10–20 years or more but may wear out eventually, requiring revision.
6. Can I drive with C5–C6 anterolisthesis?Yes if pain and mobility allow; otherwise, limit long trips until better controlled.
7. Are cervical collars helpful?Short-term use may relieve pain, but prolonged use can weaken neck muscles.
8. Will weight loss help?Losing excess weight reduces load on the cervical spine, easing pain and slowing degeneration.
9. What home remedies work best?Heat, gentle traction over a doorway, and posture correction often help mild cases.
10. How to prevent recurrence after surgery?Follow doctor’s rehab plan, avoid heavy lifting, maintain neck exercises.
11. Can anterolisthesis cause headaches?Yes—tension at C5–C6 can refer pain to the back of the head.
12. Is cervical anterolisthesis genetic?There’s no direct inheritance, but congenital spine abnormalities can increase risk.
13. Does smoking affect recovery?Yes—smoking slows bone healing and fusion after surgery.
14. How to sleep comfortably with neck slippage?Sleep supine with a cervical pillow; avoid stomach sleeping.
15. When is anterolisthesis life-threatening?Rarely; only if severe spinal cord compression causes paralysis or loss of autonomic control.
