Lumbar Parasagittal Disc Prolapse

A lumbar parasagittal disc prolapse (also called a paracentral lumbar disc herniation) occurs when the nucleus pulposus of an intervertebral disc in the lower back extrudes through a tear in the annulus fibrosus at or just off the midline (parasagittal), impinging on adjacent neural structures (nerve roots or thecal sac). This displacement can compress spinal nerves within the lateral recess or neural foramen, producing radicular symptoms (e.g., sciatica) and mechanical back pain. The process typically evolves through stages—bulge, protrusion, extrusion, and sequestration—each reflecting increasing severity of annular breach and neural compromise RadiopaediaRadiopaedia.

Disc herniation is most common at the L4–L5 and L5–S1 levels, where mechanical loads and motion are greatest; parasagittal (paracentral) herniations at these levels account for a large proportion of symptomatic cases in adults aged 30–50 years ScienceDirectWikipedia.

Anatomy of the Lumbar Intervertebral Disc

Structure & Location

The intervertebral disc is a fibrocartilaginous joint (symphysis) between adjacent vertebral bodies. In the lumbar spine, there are five discs (L1–L2 through L5–S1), each comprising:

• Annulus fibrosus: concentric lamellae of type I and II collagen fibers forming a sturdy ring.

• Nucleus pulposus: gelatinous core rich in proteoglycans (aggrecan) and water, acting as a hydraulic cushion.

• Cartilaginous endplates: thin hyaline cartilage plates that interface the disc with vertebral bodies Wikipedia.

Parasagittal (paracentral) herniations occur in the posterior-lateral 10–15% of the disc circumference, where the annular fibers are thinnest and most vulnerable to tear.

“Origin” & “Insertion” (Attachments)

• The annulus fibrosus attaches circumferentially via Sharpey’s fibers to the bony ring apophysis of each vertebral body above and below.

• The cartilaginous endplates blend into the subchondral bone of the vertebral bodies, anchoring the disc and facilitating nutrient diffusion.

• Embryologically, the nucleus pulposus is derived from notochordal remnants, while the annulus originates from sclerotomal mesenchyme PubMed.

Blood Supply

Intervertebral discs are largely avascular in adults:

• Cartilaginous endplates have capillary plexuses that supply adjacent disc regions by diffusion.

• Outer annulus receives small branches from segmental arteries (e.g., lumbar arteries) at the periphery.

• The nucleus pulposus relies entirely on diffusion of nutrients (glucose, oxygen) through the endplates Radiopaedia.

Nerve Supply

Sensory (nociceptive) fibers penetrate only the outer one-third of the annulus fibrosus, primarily via the sinuvertebral (recurrent meningeal) nerves and branches of the ventral rami. These fibers mediate discogenic pain when the annulus is torn or inflamed Ainsworth Institute.

Key Functions

1. Shock Absorption
   The nucleus pulposus distributes compressive loads hydraulically, protecting vertebral endplates.

2. Load Transmission
   Discs share ~70% of axial load with vertebral bodies, facilitating weight-bearing SpringerOpen.

3. Spinal Stability
   The annulus fibrosus resists torsional and shear forces, maintaining alignment.

4. Mobility & Flexibility
   Symphyseal joints allow slight movements (flexion, extension, rotation) between vertebrae.

5. Foraminal Spacing
   Disc height maintains the size of intervertebral foramina, preventing nerve root compression.

6. Ligamentous Function
   Together with ligaments, discs hold vertebrae in close apposition, contributing to joint integrity Wikipedia.

Types of Disc Prolapse

Morphological classification (nomenclature per Fardon et al., 2014):

• Bulge: circumferential, symmetric extension of disc beyond endplates.

• Protrusion: focal herniation < 90° of the disc circumference; base wider than protrusion.

• Extrusion: disc material extends > base width; continuity with disc remains.

• Sequestration: free fragment separated from parent disc Radiology AssistantRadiopaedia.

Locational classification (relative to midline):

• Central (midline)

• Para-central (parasagittal) – most common in lumbar region

• Foraminal (lateral recess)

• Extraforaminal (far lateral) Radiopaedia.
