Lumbar Disc Subarticular Herniation

Lumbar disc subarticular herniation occurs when the soft inner core of an intervertebral disc in the lower back bulges or leaks out through a weakness in the outer ring, pressing on nerves in the subarticular (lateral recess) zone. This can cause localized back pain, nerve irritation, and symptoms that radiate into the legs. An evidence-based understanding of this condition combines insights from anatomy, biomechanics, and clinical studies to guide safe, effective management.

Lumbar disc herniation is a condition in which intervertebral disc material—namely nucleus pulposus, portions of annulus fibrosus, or cartilage endplate—displaces beyond its normal confines, typically involving less than 25% of the disc’s circumference Radiology AssistantRadiopaedia. When this displacement occurs in the subarticular zone (also known as the lateral recess, the area just beneath the facet joint), it is termed subarticular herniation. In this variant, the herniated material encroaches upon the space where the traversing nerve root lies, most often compressing the exiting nerve root at the level immediately below the herniated disc Radiology KeyRadiopaedia.

Subarticular herniations account for a significant proportion of symptomatic lumbar disc herniations. The most commonly affected levels are L4-L5 and L5-S1, reflecting both the greatest range of motion and highest mechanical load in these segments Radiology KeyRadiopaedia. Patients typically present in the third to fifth decades of life, though presentation can occur at any age, often precipitated by degenerative changes, acute trauma, or repetitive microtrauma.

Anatomy of the Lumbar Intervertebral Disc

1. Structure

The intervertebral disc is composed of two distinct regions: the annulus fibrosus and the nucleus pulposus. The annulus fibrosus is a multilamellar fibrocartilaginous ring made of concentric lamellae of collagen fibers oriented at alternating angles, granting tensile strength and containing the nucleus. In contrast, the nucleus pulposus is a gelatinous core rich in proteoglycans and water (around 70–90 %), allowing it to resist compressive loads by distributing pressure radially to the annulus. Together, these components enable the disc to function as both a shock absorber and a flexible joint between vertebral bodies.

2. Location

Lumbar intervertebral discs sit between the vertebral bodies from L1–L2 down to L5–S1. They occupy the anterior spinal column, sandwiched superiorly and inferiorly by cartilaginous endplates on the adjacent vertebral bodies. In the subarticular (lateral recess) region, a herniation occurs just beneath the facet joint and medial to the foramen, where the traversing nerve root passes. This location makes subarticular herniations particularly prone to nerve compression in the spinal canal’s lateral recess.

3. Origin & Insertion

Unlike muscles, discs do not “originate” and “insert” in the classic sense; rather, their annulus fibrosus fibers anchor directly into the superior and inferior cartilaginous endplates of the vertebral bodies. Each lamellar ring blends at its margins into the bony endplate and the adjacent vertebral bone, ensuring that vertical loads are transmitted from one vertebra to the next without slippage.

4. Blood Supply

Intervertebral discs are largely avascular in adulthood. Nutrients reach the disc by diffusion through the cartilaginous endplates from capillary beds in the adjacent vertebral metaphyses. Small arteries—branches of the lumbar segmental arteries—supply the outer one-third of the annulus fibrosus via the peri-discal arterial plexus. The nucleus pulposus and inner annulus remain avascular, relying entirely on diffusion for nutrition and waste removal.

5. Nerve Supply

Sensory innervation of the annulus fibrosus is provided by the sinuvertebral (recurrent meningeal) nerve, which re-enters the spinal canal via the intervertebral foramen. These small nerve fibers penetrate the outer one-third of the annulus and the posterior longitudinal ligament, transmitting pain when the annulus is torn or stressed. The nucleus pulposus itself is aneural, but when it herniates and contacts these sensitized fibers or compresses nerve roots, pain signals are generated.

Functions

1. Load Transmission & Distribution
   The disc bears and evenly distributes axial loads from the body, with the nucleus pulposus transferring pressure radially into the annulus. This even distribution prevents focal stress that might otherwise damage vertebral endplates or the posterior elements.

2. Shock Absorption
   Under dynamic activities—walking, running, jumping—the hydrated nucleus acts like a hydraulic cushion, absorbing impact forces and protecting the vertebrae and spinal cord from jarring.

3. Spinal Mobility
   The viscoelastic properties of the annulus and nucleus permit flexion, extension, lateral bending, and axial rotation between vertebrae while maintaining stability.

4. Maintaining Intervertebral Height
   By preserving disc height, the disc ensures adequate size of the intervertebral foramina, preventing nerve root impingement under normal conditions.

5. Facilitating Nutrient Exchange
   Through cyclic loading and unloading (“pumping action”), the disc promotes diffusion of oxygen and nutrients into its inner regions and clearance of metabolic waste, essential for cell viability in an otherwise avascular structure.

6. Torsional Resistance
   The alternating fiber orientation of the annular lamellae affords resistance to torsional (twisting) forces, protecting the spine from injury during rotational movements.

Types of Lumbar Disc Subarticular Herniation

Subarticular herniations occur in the lateral recess, medial to the neural foramen. They are generally classified by the morphology of disc material displacement:

1. Protrusion
   A contained herniation in which the disc’s outer annular fibers bulge outward but remain intact. The herniated base is broader than its outward extension, and the nucleus remains confined.

2. Extrusion
   A more severe herniation where the nucleus pulposus breaches the annulus fibrosus but remains connected to the disc of origin by a “neck” of material. The extruded fragment’s diameter exceeds the neck’s.

3. Sequestration
   Also known as a “free fragment,” this occurs when a piece of the nucleus pulposus completely separates from the parent disc and can migrate within the spinal canal, potentially causing intermittent nerve compression.

4. Broad-based vs. Focal

   • Broad-based bulges involve more than 25 % but less than 50 % of the disc circumference.

   • Focal protrusions involve less than 25 % of the circumference, often producing more localized impingement.

5. Contained vs. Non-contained

   • Contained herniations (protrusions) keep the annulus intact.

   • Non-contained (extrusions and sequestrations) breach the annular fibers.

6. Migratory Patterns
   Sequestered fragments can migrate superiorly, inferiorly, or even dorsally within the spinal canal, altering clinical presentation and affecting surgical planning.

Lumbar disc herniations can be classified both by morphology and by location:

• Morphological Types (based on disc material displacement):

  • Bulge: Circumferential extension >180°.

  • Protrusion: Focal displacement <25% of circumference where the base of herniation is wider than its depth.

  • Extrusion: Herniated material extends beyond annulus with a base narrower than its maximum extent.

  • Sequestration: Extruded fragment separates from parent disc. Radiology Assistant.

• Anatomical Locations:

  1. Central: Into the spinal canal, often compressing the thecal sac.

  2. Paracentral: Just off midline, most common site for L4–L5 and L5–S1 herniations.

  3. Subarticular (Lateral Recess): Under the facet joint, compressing the traversing nerve root.

  4. Foraminal: Within the neural foramen, affecting the exiting nerve root.

  5. Extraforaminal (Far Lateral): Lateral to the foramen, compressing the nerve root as it exits. Radiology KeyRadiology Assistant.

Subarticular herniations specifically impinge the lateral recess, leading to traversing root symptoms, often without significant central canal compromise.

• Severe Leg Weakness or Numbness: Difficulty lifting foot (foot drop), loss of coordination.

• Loss of Bladder or Bowel Control: May indicate cauda equina syndrome—an emergency.

• Progressive Neurological Deficits: Worsening weakness, tingling, or loss of sensation.

• Unrelenting Pain: Pain not eased by rest, medications, or conservative measures for more than 6–8 weeks.

• Fever or Unexplained Weight Loss: Could suggest infection or malignancy.

Frequently Asked Questions

1. What exactly is lumbar disc subarticular herniation?

Lumbar disc subarticular herniation happens when the inner gel-like part of a lumbar disc pushes into the lateral recess (subarticular zone) under the facet joint, irritating nearby nerves and causing back and leg pain.

2. How is subarticular herniation different from a central herniation?

In central herniation, disc material bulges straight back into the spinal canal, while subarticular herniation bulges to the side under the facet joint, often causing nerve root compression in the lateral recess.

3. What are the most common symptoms?

Patients usually report lower back pain, buttock discomfort, and sciatica-type pain radiating down one leg. Numbness, tingling, or muscle weakness may occur along the affected nerve’s pathway.

4. How is it diagnosed?

Diagnosis relies on clinical exam—checking reflexes, strength, and sensation—plus imaging tests like MRI, which can clearly show the location and size of the herniation.

5. Can a subarticular herniation heal on its own?

Yes. Many small herniations shrink over weeks to months as the body reabsorbs disc material. Conservative care often resolves symptoms without surgery.

6. How long does recovery take with non-surgical treatment?

With proper therapy and self-care, most people improve significantly within 6–12 weeks. Some residual discomfort can persist but usually becomes manageable.

7. Do I always need an MRI?

Not always. If symptoms are mild and improve with conservative care, imaging may be postponed. MRI is recommended if “red flags” appear or if surgery is being considered.

8. Which activities should I avoid?

Avoid heavy lifting, twisting at the waist, and prolonged sitting or bending. These increase pressure on the affected disc and can worsen symptoms.

9. When should I consider surgery?

Surgery may be considered if severe nerve compression causes significant weakness, intractable pain, or if conservative treatments fail after 6–8 weeks.

10. Are there long-term risks?

If left untreated, chronic nerve compression can cause permanent nerve damage. Surgery has its own risks, including infection and adjacent segment disease.

11. Can physical therapy really help?

Yes. A tailored program of manual therapy, exercises, and education can reduce pain, restore function, and prevent recurrences in most patients.

12. Are pain medications safe for long-term use?

NSAIDs and acetaminophen are generally safe for short-term use. Long-term use increases risks of GI bleeding, kidney injury, or liver toxicity. Opioids carry dependence risks and should be used cautiously.

13. What lifestyle changes help prevent relapse?

Maintain a healthy weight, strengthen core muscles, practice good posture, use ergonomic furniture, and stay active with low-impact exercise like swimming or walking.

14. Can supplements reduce my pain?

Supplements like glucosamine, curcumin, and omega-3s have evidence supporting mild anti-inflammatory effects, but they work best as part of a comprehensive treatment plan.

15. What are the risks of surgery?

Risks include infection, nerve damage, bleeding, and failure to relieve pain. However, minimally invasive techniques like microdiscectomy have lower complication rates and faster recovery.
