Lumbar Intradural Disc Prolapse

Lumbar intradural disc prolapse (also called intradural disc herniation, IDH) is an exceedingly rare form of intervertebral disc herniation in which nucleus pulposus material not only breaches the annulus fibrosus and posterior longitudinal ligament but also penetrates the dura mater, lodging within the intradural (subdural or subarachnoid) space of the spinal canal RadiopaediaPMC. Clinically, it accounts for roughly 0.2–2.2% of all lumbar disc herniations and most commonly involves the L4–L5 level Lippincott Journals. The pathogenesis appears related to chronic degenerative changes that weaken protective ligaments and dura, alongside acute mechanical stresses that force disc material through these barriers PMCPMC. Definitive diagnosis often requires intraoperative confirmation, though preoperative MRI or CT myelography may suggest intradural extension when a “ring enhancement” or contrast leakage into the thecal sac is visible Radiopaedia.

Anatomy of the Intervertebral Disc in the Context of Intradural Prolapse

Although intradural prolapse refers to the pathologic migration of disc material into the dural sac, understanding the normal anatomy of the lumbar intervertebral disc is essential. Below is a detailed breakdown:

1. Structure and Location

The intervertebral disc is a fibrocartilaginous joint situated between adjacent vertebral bodies from C2/3 through L5/S1. In the lumbar spine, discs are largest at L4–L5 and L5–S1, bearing significant axial load Kenhub. Each disc comprises two main components:

• Annulus fibrosus: Concentric lamellae of collagen fibers arranged obliquely, providing tensile strength and containing the nucleus pulposus.

• Nucleus pulposus: A gelatinous core rich in proteoglycans and water, allowing compressibility and shock absorption.

In intradural prolapse, fragments of this nucleus breach the annulus, posterior longitudinal ligament, and dura mater, ultimately residing within the dural sac.

2. Origin and Insertion

Unlike muscles, the disc itself does not “originate” or “insert” on bone; rather, its outer annulus fibrosus binds directly to the vertebral endplates of the superior and inferior vertebral bodies via Sharpey’s fibers Kenhub. These endplates consist of hyaline cartilage that:

• Anchors annular fibers to prevent slippage.

• Transmits nutrient diffusion between vertebral cancellous bone and the avascular disc.

In IDH, degeneration or microtears of these attachment zones can facilitate disc material extrusion beyond the bony confines into the spinal canal and, more rarely, into the intradural compartment.

3. Blood Supply

By adulthood, the intervertebral disc is largely avascular, relying on diffusion through the cartilaginous endplates for nutrition. During fetal development and early infancy, small vessels penetrate the outer annulus; these regress by adolescence Kenhub. Key facts:

• Endplate diffusion: Nutrients (glucose, oxygen) diffuse from capillaries in adjacent vertebral bodies across the endplates.

• Peripheral capillaries: A sparse network at the outer annulus may persist, supplying the outermost one-third of the annular lamellae.

• Impairment in degeneration: Endplate sclerosis and calcification reduce diffusion, accelerating degenerative changes that predispose to herniation.

4. Nerve Supply

Pain and proprioceptive fibers enter the disc primarily via the recurrent meningeal (sinuvertebral) nerves, which emanate from the ventral ramus and sympathetic trunks Orthobullets. Details include:

• Outer annulus: Richly innervated; nociceptors detect annular tears and mechanical strain.

• Posterior longitudinal ligament: Also innervated by sinuvertebral nerves, explaining back pain when this ligament is stretched or disrupted.

• Intradural involvement: When disc fragments enter the dura, inflammatory mediators and direct compression irritate dorsal root ganglia and nerve roots, amplifying radicular symptoms.

5. Core Functions

Beyond serving as spacers, lumbar discs perform multiple biomechanical roles:

1. Shock Absorption
   The high water content of the nucleus pulposus allows the disc to deform elastically under load, dissipating forces generated during activities such as walking or jumping Kenhub.

2. Load Transmission
   Discs distribute compressive loads evenly across vertebral endplates, minimizing peak stresses on bony structures and preventing fracture Kenhub.

3. Range of Motion Facilitation
   The flexibility of the annulus fibrosus and compressibility of the nucleus permit flexion, extension, lateral bending, and axial rotation of the lumbar spine.

4. Spinal Stability
   The annular fibers, arranged in alternating concentric layers, resist shear and torsional forces, maintaining vertebral alignment under dynamic loads.

5. Intervertebral Spacing
   By maintaining disc height, they preserve foraminal dimensions, allowing unimpeded exit of spinal nerve roots.

6. Nutrient Diffusion Reservoir
   The disc’s hydrated matrix serves as a reservoir for nutrient exchange; cyclical compression-decompression during movement pumps synovial fluid and nutrients through the endplates.

Types of Lumbar Intradural Disc Prolapse

While all intradural herniations share dural penetration, they can be subclassified based on exact localization and relationship to neural structures:

1. Intradural Extramedullary Prolapse
   Disc fragments lie within the dural sac but outside the spinal cord substance, often adjacent to nerve roots in the thecal sac. This is the most common intradural subtype in the lumbar region.

2. Intramedullary Prolapse
   Extremely rare, here nucleus material penetrates into the spinal cord parenchyma itself, usually at the conus or cauda equina junction, causing central cord compression.

3. Intraradicular Prolapse
   Fragments lodge within the dural sleeve of a specific nerve root, leading to isolated radicular symptoms without diffuse cauda equina involvement.

4. Transarachnoid Prolapse
   Migration occurs through both dura and arachnoid layers; disc material floats freely in CSF, sometimes mimicking arachnoid cysts on MRI.

Causes of Lumbar Intradural Disc Prolapse

1. Degenerative Disc Disease: Age-related dehydration and fissuring of the annulus fibrosus weaken barriers to herniation.

2. Acute Trauma: Falls or traffic accidents abruptly increase intradiscal pressure, forcing nucleus pulposus outward.

3. Repetitive Microtrauma: Chronic heavy lifting or vibration (e.g., machinery operators) causes cumulative annular injury.

4. Genetic Predisposition: Polymorphisms in collagen and matrix metalloproteinase genes accelerate disc degeneration.

5. Smoking: Nicotine impairs endplate blood flow, reducing disc nutrition and matrix repair.

6. Obesity: Increased axial load accelerates annular tears and nucleus displacement.

7. Poor Posture: Chronic flexed or rotated postures strain posterior annulus fibers.

8. Occupational Strain: Jobs requiring frequent bending, twisting, or awkward lifting magnify disc stress.

9. Vascular Insufficiency: Endplate microangiopathy from diabetes or atherosclerosis limits disc nutrition.

10. Connective Tissue Disorders: Ehlers–Danlos and Marfan syndromes can weaken annular fibers and dura mater.

11. Previous Spinal Surgery: Scar tissue and altered biomechanics increase adjacent segment stress.

12. Inflammatory Arthropathy: Ankylosing spondylitis and rheumatoid arthritis erode ligamentous support.

13. Intradiscal Steroid Injection: Rarely, iatrogenic needle injury breaches annulus leading to migration.

14. Rapid Weight Loss: Sudden reduction in paraspinal muscle mass destabilizes segments, increasing disc strain.

15. High-impact Sports: Gymnastics, weightlifting, and contact sports expose discs to explosive forces.

16. Metabolic Bone Disease: Osteoporosis and Paget’s disease alter vertebral endplates, promoting fissures.

17. Spinal Deformity: Scoliosis and hyperlordosis unevenly distribute pressures across discs.

18. Tumor Erosion: Rarely, neoplasms can erode dura and permit herniation, though primary disc disease is usual.

19. Infection: Discitis weakens annulus and may facilitate prolapse into the intradural space.

20. Idiopathic Dural Weakness: Congenital thinning of the dura can predispose to spontaneous penetration by disc material.

Diagnostic Tests

A. Physical Examination

1. Posture Assessment: Observe spinal alignment; a forward-flexed posture often relieves intradural root tension.

2. Gait Analysis: Identify limping, foot drop, or antalgic gait indicative of motor compromise.

3. Range of Motion (ROM): Measure flexion, extension, lateral bending; restriction suggests mechanical irritation.

4. Palpation of Spinous Processes: Tenderness over the affected segment may localize pathology.

5. Paraspinal Muscle Tone: Rigidity or spasm signals protective guarding from pain.

6. Neurological Screening: Quick check of motor strength, reflexes, and sensation to identify deficits.

B. Manual Tests

1. Straight Leg Raise (SLR): Elevating the leg between 30°–70° reproduces sciatic pain in positive tests.

2. Crossed SLR: Raising the contralateral leg elicits pain on the symptomatic side, highly specific for disc herniation.

3. Slump Test: Seated slump with neck flexion and ankle dorsiflexion stretches neural structures to reproduce symptoms.

4. Femoral Nerve Stretch Test: Prone knee flexion stretching the femoral nerve provokes anterior thigh pain in upper lumbar root lesions.

5. Schober’s Test: Measures lumbar flexion; reduced flexion may indicate pain-limiting herniation.

6. Kemp’s Test: Extension and rotation of the spine elicit localized or radiating pain when facet or root is irritated.

C. Lab & Pathological Tests

1. Complete Blood Count (CBC): Rules out infection or inflammatory causes when WBC counts are elevated.

2. Erythrocyte Sedimentation Rate (ESR): Elevated in discitis or autoimmune arthropathy.

3. C-Reactive Protein (CRP): Acute phase reactant rises rapidly with inflammation or infection.

4. Rheumatoid Factor & ANA: Exclude systemic rheumatologic conditions that can mimic disc pathology.

5. HLA-B27 Typing: Positive in ankylosing spondylitis, which may alter ligamentous integrity.

6. Histopathological Examination: When surgery is performed, microscopic analysis of disc fragments confirms degeneration and rules out neoplasm.

D. Electrodiagnostic Tests

1. Nerve Conduction Studies (NCS): Measures conduction velocity; slowed signals indicate root compression.

2. Electromyography (EMG): Detects denervation potentials in muscles innervated by affected roots.

3. Somatosensory Evoked Potentials (SSEPs): Assesses dorsal column function; may be abnormal if intradural mass effect exists.

4. Motor Evoked Potentials (MEPs): Evaluates corticospinal tract integrity; prolonged latencies suggest central compression.

5. F-Wave Studies: Probes proximal nerve segments; delayed F-waves point to root pathology.

6. H-Reflex Testing: Analogous to ankle reflex; reduced amplitude indicates S1 root involvement.

E. Imaging Tests

1. Plain Radiography (X-ray): Initial screen for alignment, vertebral anomalies, and degenerative changes.

2. Computed Tomography (CT): Detects calcified disc fragments and bony details; limited for soft tissue.

3. Magnetic Resonance Imaging (MRI): Gold standard for visualizing disc material breaching the dura and assessing nerve root compression.

4. CT Myelography: Contrast in the intradural space outlines filling defects from herniated disc fragments.

5. MRI Myelography: Heavily T2-weighted imaging shows CSF flow interruption around intradural masses without intrathecal contrast.

6. Discography: Injection of contrast into the disc reproduces pain and can demonstrate annular tears, though rarely used for intradural suspicion.
