Cervical Disc Lateral Recess Protrusion

A cervical disc lateral recess protrusion occurs when the soft, gel-like center of an intervertebral disc in the neck (cervical spine) bulges backward into the space called the lateral recess, compressing nearby nerve roots. This can irritate or press on spinal nerves, leading to pain, numbness, or weakness that radiates into the shoulder, arm, or hand. Verywell Health

Anatomy

1. Structure & Location

   • The cervical spine comprises seven vertebrae (C1–C7).

   • Between each pair lies an intervertebral disc made of an outer fibrous ring (annulus fibrosus) and a soft inner nucleus pulposus.

   • The lateral recess is a narrow channel on each side of the spinal canal where nerve roots descend before exiting through the neural foramen. ScienceDirect

2. Origin & Insertion

   • Discs “originate” between vertebral bodies, attaching via the endplates of each bone above and below.

   • They “insert” snugly, acting as cushions and spacers, maintaining distance and flexibility between vertebrae.

3. Blood Supply

   • Cervical discs are largely avascular internally; they receive nutrition by diffusion from tiny capillaries in the vertebral endplates.

   • Surrounding vertebral bodies receive branches from vertebral and ascending cervical arteries. Physiopedia

4. Nerve Supply

   • Outer annulus fibrosus has sensory fibers from the sinuvertebral (recurrent meningeal) nerves, detecting pain when the disc is injured. Physiopedia

5. Functions

   1. Shock absorption during head movement.

   2. Maintaining spinal alignment and curvature.

   3. Allowing flexion, extension, lateral bending, and rotation of the neck.

   4. Distributing loads evenly across vertebral bodies.

   5. Protecting spinal cord and nerve roots by spacing vertebrae.

   6. Facilitating nutrient exchange via endplate diffusion.

Types of Lateral Recess Protrusion

1. Mild Protrusion: Disc bulges <3 mm into the recess.

2. Moderate Protrusion: Bulge 3–5 mm, may touch the nerve root.

3. Severe Protrusion: Bulge >5 mm, compresses the nerve root significantly.

4. Contained Protrusion: Annulus fibrosus intact, nucleus still contained.

5. Uncontained (Extruded): Annulus torn, nucleus material extends into nearby spaces.

13. Dynamic MRI: In flexion/extension, less commonly used.

14. Somatosensory evoked potentials (SSEPs): Measure spinal cord function.

15. Motor evoked potentials (MEPs): Evaluate motor pathway integrity.

16. Blood tests: Exclude inflammatory or infectious causes.

17. CT angiography: If vascular compression suspected.

18. Myelogram: Contrast in the thecal sac, older technique.

 FAQs

1. What exactly is a lateral recess?
   The lateral recess is a side channel of the spinal canal where nerve roots travel before exiting the spine through foramina.

2. How does a protrusion differ from a herniation?
   A protrusion bulges but remains contained by the annulus fibrosus; a herniation means the nucleus breaks through the annulus.

3. Can imaging miss a lateral recess protrusion?
   Rarely. MRI is very sensitive; CT myelogram helps if MRI is inconclusive.

4. Is surgery always required?
   No. Most cases improve with non-surgical care over 6–12 weeks.

5. How long does recovery take?
   Non-surgical: weeks to months. Surgical: often full recovery by 3–6 months.

6. Will I need a fusion after discectomy?
   Often yes with ACDF, but disc replacement or posterior foraminotomy may avoid fusion.

7. Can physical therapy worsen my condition?
   Properly guided therapy helps; avoid aggressive movements that worsen pain.

8. Are there exercises I should avoid?
   Heavy overhead lifting and prolonged neck hyperextension can aggravate the recess.

9. Is acupuncture effective?
   Many patients find acupuncture helpful for pain relief, but evidence varies.

10. Can weight loss reduce symptoms?
    Yes—less load on the spine means less nerve irritation.

11. What lifestyle changes help?
    Posture correction, ergonomic adjustments, regular low-impact exercise.

12. Are injections safe?
    Epidural steroid injections are generally safe but carry small risks (infection, bleeding).

13. Will my condition worsen over time?
    Degenerative changes progress slowly; early care slows or halts worsening.

14. Can I return to sports?
    Most return with guided rehab; high-impact sports may require caution.

15. How can I prevent recurrence?
    Ongoing posture awareness, strengthening exercises, and ergonomic habits.
