Prolapsed Cervical Intervertebral Disc Between C3–C4

A prolapsed (herniated) disc at the C3–C4 level occurs when the soft inner core of the intervertebral disc pushes through a tear in its outer ring, pressing on nearby nerves. This can cause neck pain, arm weakness, numbness, and other symptoms. Understanding the anatomy, causes, symptoms, diagnostic methods, and treatments helps patients and caregivers recognize the condition early and seek proper care.

Anatomy of the C3–C4 Intervertebral Disc

Structure

The C3–C4 intervertebral disc is a cushion-like fibrocartilaginous pad located between the third and fourth cervical vertebral bodies. It consists of a tough outer ring called the annulus fibrosus and a soft, gel-like center called the nucleus pulposus, which work together to absorb shock and allow movement NCBI.

Location

This disc sits directly between the C3 and C4 vertebrae in the neck region of the spine. It helps separate and connect these vertebrae, creating the necessary space for nerve roots to exit the spinal canal Kenhub.

Origin & Insertion

The annulus fibrosus attaches securely to the bony endplates of the C3 and C4 vertebral bodies. These attachments anchor the disc in place, preventing excessive slippage while allowing slight movement ScienceDirect.

Blood Supply

Small blood vessels from the adjacent vertebral bodies penetrate the outer layers of the annulus fibrosus, supplying nutrients. However, the inner nucleus pulposus relies on diffusion for its nutrient needs due to low direct blood flow ScienceDirect.

Nerve Supply

Sensory nerve fibers from the sinuvertebral (recurrent meningeal) nerves and branches of the C3–C4 spinal nerves supply the disc’s outer annulus. These fibers can transmit pain signals when the disc is injured or inflamed Medscape.

Key Functions

1. Shock Absorption: The nucleus pulposus disperses forces from daily activities, protecting vertebrae NCBI.

2. Load Bearing: Distributes weight evenly across vertebrae during posture and movement NCBI.

3. Flexibility: Allows the neck to flex, extend, and rotate smoothly Physiopedia.

4. Stability: Helps maintain proper alignment of the cervical spine Physiopedia.

5. Spacing: Keeps vertebral bodies apart to prevent bone-on-bone contact and permit nerve exit NCBI.

6. Torsion Resistance: Resists twisting forces to protect spinal cord and nerve roots Physiopedia.

Types of C3–C4 Disc Prolapse

Disc herniations at C3–C4 can be classified by shape and location:

• Bulging Disc: Broad-based extension of the disc margin.

• Protrusion: Localized bulge where the base is wider than the displaced material.

• Extrusion: Inner nucleus pushes out beyond the annulus fibrosus.

• Sequestration: A fragment of disc material separates completely and may migrate.

• Central, Posterolateral & Foraminal: Depending on whether the herniation presses on the spinal cord (central), nerve root (posterolateral), or exits through the foramen (foraminal) NCBI.

FAQs

1. What is a prolapsed C3–C4 disc?
A prolapsed disc at C3–C4 means the inner gel (nucleus) pushes out through a tear in the outer ring, often pressing on nerves and causing pain SELF.

2. Can a C3–C4 herniation heal on its own?
Yes. About 80 % of cervical herniations improve with conservative care (rest, physiotherapy) over 6–12 weeks Physiopedia.

3. What exercises help a herniated cervical disc?
Gentle chin-tucks, deep neck flexor strengthening, and McKenzie extension exercises maintain alignment and relieve pressure Physiopedia.

4. When is surgery necessary?
Surgery is considered if there is severe or worsening neurological deficit, intractable pain despite 6–12 weeks of conservative care, or spinal cord compression signs Physiopedia.

5. How long is recovery after ACDF?
Most patients return to light activities in 2–4 weeks, with full activity by 3–6 months, depending on fusion success Best Hospital Hyderabad.

6. Are there risks with cervical traction?
Minor risks include discomfort, headache, or increased pain if performed improperly; always under professional guidance NCBI.

7. Can poor posture cause disc herniation?
Yes—forward head posture increases disc pressure, accelerating wear and tear PMC.

8. Will smoking affect my disc?
Smoking reduces blood flow to discs, speeding degeneration and delaying healing drfanaee.com.

9. Is MRI safe for diagnosing a herniation?
Yes. MRI uses magnetic fields (no radiation) and provides clear images of soft tissues including discs and nerves.

10. Does age affect prognosis?
Older patients may recover more slowly, but many still respond well to conservative and surgical treatments.

11. Can chiropractic help?
Careful cervical manipulation by a licensed chiropractor may relieve pain, but should be avoided if there is severe cord compression.

12. How can I prevent recurrence?
Maintain neck strength, posture, weight, and avoid high-risk activities to reduce future herniation risk.

13. What is Lhermitte’s sign?
An electric-shock sensation down the spine when bending the neck, indicating possible cord irritation Verywell Health.

14. Are injections effective?
Epidural steroid injections can provide targeted relief, often delaying or avoiding surgery Spine-health.

15. When should I avoid cervical collars?
Long-term collar use can weaken neck muscles; use only short-term (days to weeks) under medical advice Physiopedia.
