Lumbar Disc Contained Extrusion

Lumbar disc contained extrusion is a subtype of intervertebral disc herniation in which the nucleus pulposus breaches the annulus fibrosus yet remains contained by the outer annular fibers and/or the posterior longitudinal ligament (PLL), rather than fully migrating into the epidural space. This containment influences both clinical presentation and natural history, often correlating with a more favorable prognosis compared to uncontained extrusions NCBIRadiology Assistant.

According to the 2014 North American Spine Society (NASS) consensus (“Lumbar Disc Nomenclature 2.0”), an extrusion is defined radiologically when the maximum width of displaced disc material exceeds the width at its base. When this extruded material is still covered by annular fibers or the PLL, it is specifically termed a contained extrusion Radiology AssistantRadiology Assistant.

A contained lumbar disc extrusion occurs when the disc’s inner nucleus bulges through a tear in the annulus fibrosus but remains enveloped by the outer annular fibers or posterior longitudinal ligament. Unlike a free or sequestered extrusion—where disc material migrates into the spinal canal—a contained extrusion stays partially within the disc space. This partial herniation can irritate nearby nerve roots, causing localized back pain, radiating leg pain (sciatica), numbness, tingling, or muscle weakness. Over time, inflammation around the extruded material may resolve on its own, but persistent cases often require targeted therapies to reduce nerve irritation and improve function.

Anatomy of the Lumbar Intervertebral Disc

Structure

The lumbar intervertebral disc is a composite fibrocartilaginous joint comprising three elements:

1. Nucleus pulposus (NP): A gelatinous core rich in proteoglycans and water, conferring hydrostatic pressure–based shock absorption.

2. Annulus fibrosus (AF): Concentric lamellae of type I collagen fibers arranged at oblique angles, providing tensile strength and containment of the nucleus.

3. Cartilaginous endplates: Thin hyaline cartilage layers that anchor the disc to adjacent vertebral bodies and mediate nutrient diffusion WikipediaNCBI.

Location

Five lumbar discs (L1–L2 through L5–S1) reside between the vertebral bodies, constituting the largest and most caudal intervertebral segments. Their central positioning in the mobile lumbar lordosis makes them especially susceptible to axial loading and flexion‐extension stresses WikipediaKenhub.

Origin & Insertion

Each disc attaches via its cartilaginous endplates to the superior and inferior vertebral bodies. The annulus fibrosus anchors to the peripheral ring apophysis of the vertebral bodies, while the nucleus pulposus is contiguous only with the inner endplate surfaces. Unlike a tendon or ligament, the disc has no musculotendinous origin or insertion; its firm integration into vertebral bodies permits force transmission across spinal segments Wheeless’ Textbook of OrthopaedicsWikipedia.

Blood Supply

In adults, intervertebral discs are largely avascular:

• Nucleus pulposus: Completely devoid of direct vessels throughout life.

• Inner annulus fibrosus: Receives nutrients by diffusion through the cartilaginous endplates from capillaries of the vertebral subchondral bone.

• Outer annulus fibrosus: Supplied by small branches of lumbar segmental arteries that penetrate roughly the outer third of the annular lamellae.
  Vascular regression typically completes by early childhood, leaving only sporadic vessels in damaged or degenerated discs NCBIPMC.

Nerve Supply

Sensory innervation of the lumbar disc is confined to the outer third of the annulus fibrosus. The principal carriers are:

• Sinuvertebral (recurrent meningeal) nerves: Branches of the ventral rami that re‐enter the spinal canal to innervate the posterior annulus and posterior longitudinal ligament.

• Grey rami communicantes and lateral branches of ventral rami: Supply the lateral aspects of the annulus.
  Nuclear material itself lacks nociceptive fibers; annular tears or neovascular ingrowth in degeneration permit nociceptor proliferation, mediating discogenic pain RadiopaediaWikipedia.

Functions

1. Load transmission: Evenly distributes axial forces across vertebral bodies, preventing focal overload.

2. Shock absorption: The hydrated nucleus resists compressive forces via hydrostatic dynamics.

3. Mobility: Enables flexion, extension, lateral bending, and axial rotation through the annular fiber orientation.

4. Intervertebral spacing: Maintains foraminal height for unimpeded exit of spinal nerves.

5. Stability: Resists shear and torsional stresses thanks to annular fiber architecture.

6. Energy dissipation: Minimizes mechanical vibrations transmitted during dynamic activities NCBINCBI.

Types of Disc Herniation (Classification)

Modern nomenclature divides herniated discs into:

• Protrusion: Focal disc bulge where the base at the annulus is wider than the herniated tip.

• Contained extrusion: Disc fragment extrudes beyond endplate confines, the extruded portion is wider than its neck, but remains within annular fibers.

• Non‐contained extrusion (Sequestration): Extruded material breaches all annular constraints, detaching as a free fragment.
  Further subclassifications include:

• Morphological:

  • Focal (<90° of disc circumference) vs broad‐based (90–180°).

• Topographical:

  • Central, paracentral, foraminal, extraforaminal based on relation to neural foramen.
    These distinctions guide prognosis and surgical planning Radiology AssistantRadiopaedia.

2. Heavy Lifting or Twisting: Increases disc pressure and pain.

3. High-Impact Sports: Running or jumping until pain resolves.

4. Prolonged Sitting: Especially in unsupported chairs.

5. Ignoring Warning Signs: Don’t delay care if red flags develop.
