Cervical Retrolisthesis at C6 over C7

Cervical retrolisthesis at C6 over C7 is a backward slipping of the sixth cervical vertebra (C6) relative to the seventh (C7). Unlike a normal spine alignment where each vertebra sits directly atop the one below, retrolisthesis means C6 has moved slightly toward the back. This displacement can pinch nerves, strain muscles, and alter the curve of the neck, leading to pain and reduced motion.

Anatomy

Structure and Location

• Vertebrae: The cervical spine has seven small vertebrae (C1–C7). C6 and C7 are at the lower end of the neck.

• Facet Joints: Small joints between vertebrae that guide motion.

• Intervertebral Disc: A soft, gel-like cushion between each vertebra absorbing shock.

Origin and Insertion

• Origin: The posterior elements of C6, including the lamina and facets, attach to muscles (e.g., semispinalis cervicis originates partly on C6).

• Insertion: Ligaments (e.g., the posterior longitudinal ligament) run along the back of C6, attaching to C7 and other levels to stabilize alignment.

Blood Supply

• Vertebral Arteries: Arise from the subclavian arteries, running through the transverse foramina of C6 up into the skull. They supply blood to the spinal cord and brainstem.

Nerve Supply

• Cervical Nerve Roots: The C7 nerve root exits just below C6. If C6 slips backward, it can irritate the C7 root, leading to pain or numbness in its distribution (back of arm, middle finger).

Functions

1. Support: Carries the weight of the head.

2. Protection: Encases and shields the spinal cord.

3. Motion: Allows flexion, extension, rotation, and side bending of the head and neck.

4. Shock Absorption: Intervertebral discs cushion forces.

5. Load Transmission: Transfers loads from the head to the thoracic spine.

6. Postural Control: Maintains the cervical curve crucial for balance.

Types of Cervical Retrolisthesis

1. Anterior Retrolisthesis: Forward slip; rare at C6–C7.

2. Posterior Retrolisthesis: Backward slip (what we describe).

3. Translation: Pure sliding without tilt.

4. Rotatory: Involves twisting of one vertebra relative to another.

5. Degenerative: Caused by wear-and-tear of discs and joints.

6. Traumatic: From sudden injuries (e.g., falls).

7. Post-surgical: Occurs after neck surgery.

8. Pathologic: Due to tumors or infections weakening structures.

---

Causes

1. Degenerative disc disease: Disc thinning leads to instability.

2. Osteoarthritis: Joint wear loosens facet joints.

3. Whiplash injury: Sudden hyperextension-flexion strains ligaments.

4. Repetitive stress: Heavy lifting or forward head posture.

5. Congenital anomalies: Abnormal vertebral shapes.

6. Rheumatoid arthritis: Inflammation erodes joint surfaces.

7. Spinal infection: Weakens bone and ligaments.

9. Osteoporosis: Bone loss reduces vertebral strength.

10. Spondylolysis: Stress fractures in the vertebral arch.

11. Previous neck surgery: Alters stability.

12. Obesity: Extra load on the spine.

13. Smoking: Impairs disc nutrition.

14. Poor posture: Forward head increases strain.

15. Genetic predisposition: Family history of spine issues.

Frequently Asked Questions

1. What is the difference between retrolisthesis and spondylolisthesis?
   Retrolisthesis is backward slip; spondylolisthesis usually refers to forward slip.

2. Can cervical retrolisthesis heal on its own?
   Mild cases may improve with rest, therapy, and exercise over weeks to months.

3. Is surgery always required?
   No. Most respond to non-surgical care. Surgery is for severe or progressive cases.

4. How long does recovery take?
   Non-surgical recovery: 6–12 weeks. Post-surgery: 3–6 months for fusion healing.

5. Will my motion be limited?
   Some loss of motion may occur, especially after fusion surgery.

6. Can I continue working?
   Many return to light work in a few weeks; heavy labor may require longer rest.

7. Is caffeine bad for my discs?
   Excessive caffeine can dehydrate discs; moderate intake is acceptable.

8. Does retrolisthesis cause headaches?
   Yes, muscle strain and nerve irritation at C6–C7 can trigger headaches.

9. Are neck braces helpful?
   Soft collars help short-term rest but are not recommended for long-term use.

10. Can I drive with this condition?
    Only if neck motion and strength are adequate; ask your doctor.

11. Is chiropractic safe?
    Gentle adjustments by a licensed chiropractor can help, but aggressive thrusts should be avoided.

12. What exercises should I avoid?
    Heavy overhead lifts, neck hyperextension, and sustained forward head positions.

13. Does weight loss improve symptoms?
    Yes—reducing overall load on the spine often reduces pain.

14. Can I use a cervical pillow?
    Yes—a supportive pillow maintains natural neck curvature during sleep.

15. Are injections effective?
    Epidural steroid injections can reduce inflammation and pain temporarily.
