Lumbar Disc Sequestration at L4–L5

Lumbar disc sequestration is one of the most advanced forms of lumbar disc herniation. It occurs when a portion of the nucleus pulposus (the soft inner core of the disc) completely separates, migrates through the outer annulus fibrosus, and comes to rest somewhere inside the spinal canal. The free fragment can wander upward or downward, press on the spinal cord or nerve roots, and provoke inflammation that is often more painful than simple mechanical compression. When sequestration happens between the fourth and fifth lumbar vertebrae (L4–L5) it threatens the L5 nerve root and, if the fragment descends, sometimes the S1 root as well. Because L4–L5 bears enormous daily load, produces the largest bending moment of the lumbar region, and allows substantial flexion and extension, it is the most common single level for sequestration injuries.

Lumbar disc sequestration occurs when a fragment of the nucleus pulposus breaks completely away from the L4-L5 intervertebral disc and migrates into the spinal canal. Because the fragment is no longer attached to the parent disc, it can wander up or down the epidural space and press on nerve roots or the dural sac, producing intense low-back pain, sciatica, and sometimes cauda-equina-like symptoms.

Anatomy of the L4–L5 Intervertebral Disc

Structure

An intervertebral disc is a fibro-cartilaginous sandwich. At its center is the nucleus pulposus—a gelatinous, avascular mix of water (70 – 90 %), proteoglycans, and type II collagen. Surrounding it is the annulus fibrosus, a series of 15–25 concentric lamellae of type I collagen arranged in alternating criss-cross fashion for strength. Superiorly and inferiorly the disc is capped by thin hyaline cartilage endplates that anchor it to the adjacent vertebral bodies. The posterior annulus is thinner, which partly explains why herniations and sequestration pieces usually travel backward into the canal. During the third decade of life vascular channels regress; thereafter the disc relies entirely on diffusion through the endplates for nutrition, making it vulnerable to degenerative changes.

Location

The L4–L5 disc sits immediately anterior to the cauda equina, bordered above by the inferior endplate of L4 and below by the superior endplate of L5. Posteriorly, the ligamentum flavum and facet joints form part of the boundary of the spinal canal at this level. The disc lies just medial to each L4–L5 foramen where the L4 exiting nerve root passes, but the sequestered fragment more often impinges on the L5 traversing root lying medial to the pedicle.

Embryologic Origin

Discs develop from the notochord and sclerotome portions of somites. By the eighth gestational week the notochord regresses inside each vertebral body yet persists between bodies as the primitive nucleus pulposus. Sclerotomal mesenchyme condenses around the notochord, differentiates into annulus fibrosus layers, and later ossifies peripherally to become vertebral bone. Understanding this origin explains why the nucleus retains notochord-derived proteins that can trigger a brisk autoimmune-style inflammatory response once they escape confinement in sequestration.

Insertions and Attachments

Although the disc is not a tendon, its outer annulus anchors firmly into the ring apophysis of both vertebral bodies by Sharpey-type collagen fibers; this “enthesis” acts like the insertion of a ligament. The cartilage endplate inserts into the subchondral bone, acting as a diffusion gateway. Posteriorly, the posterior longitudinal ligament blends with the annulus, so a large extrusion may pierce both structures and enter the canal.

Blood Supply

By adulthood the disc is essentially avascular. Small capillary loops from peri-endplate arteries penetrate only the outermost annulus and the cartilage endplate. Nutrition (glucose, oxygen) and waste removal depend on diffusion down steep concentration gradients. Any factor that impairs endplate perfusion—atherosclerosis, smoking, or sustained compression—starves the nucleus of nutrients, accelerates dehydration, and weakens disc integrity, setting the stage for sequestration.

Nerve Supply

The outer one-third of the annulus receives sensory innervation from the sinuvertebral nerve (a recurrent branch of each spinal nerve) and the grey rami communicantes (sympathetic fibers). Additional fibers arise from the ventral primary rami and from branches of the vertebral and basivertebral nerves. When the annulus tears, these nociceptors and mechanoreceptors fire intensely; if nucleus material contacts them, chemical mediators (phospholipase A2, TNF-α, IL-6) heighten the pain.

Functions of the L4–L5 Disc

1. Shock absorption – Hydrostatic pressure within the nucleus cushions axial loads from walking, running, and lifting.

2. Weight distribution – Lamellar collagen directs compressive forces radially then transfers them uniformly to the strong ring apophysis.

3. Spinal flexibility – Viscous nucleus and elastic annulus allow approximately 15°–20° of flexion–extension and 5°–7° of axial rotation at L4–L5.

4. Maintenance of neural foraminal height – Adequate disc height prevents stenosis of the L4 and L5 foramina; collapse narrows them.

5. Hydraulic fulcrum for segmental motion – Nucleus migration during bending centers the instantaneous axis of rotation, keeping movement smooth.

6. Nutrient conduit – Pumping action during spinal motion drives solute diffusion across the endplates, nourishing the avascular disc itself.

When sequestration occurs, nearly all of these functions fail: shock absorption declines, segmental instability increases, cytokines leak, and foraminal dimensions shrink—explaining the complex symptom pattern patients report.

Types of Lumbar Disc Sequestration

Although “sequestration” already indicates a free fragment, clinicians further categorize it by shape, location, and migration pathway:

• Central sequestered fragment – Lies in the midline anterior to the cauda equina, often producing bilateral symptoms or cauda equina syndrome.

• Paracentral sequestered fragment – Migrates just off-midline into the lateral recess; the commonest pattern at L4–L5, typically compressing the L5 root.

• Foraminal (extraforaminal) sequestration – Travels laterally through a rent in the annulus and posterior longitudinal ligament, residing inside or beyond the neural foramen, sometimes trapping the exiting L4 root.

• Superiorly migrated fragment – Climbs one or more levels upward (e.g., into the L3–L4 recess) following the sloping posterior longitudinal ligament; superior migration is more frequent at L4–L5.

• Inferiorly migrated fragment – Descends toward L5–S1; may irritate both the traversing L5 and the S1 roots.

• Sequestration with intradural extension – Rare, the fragment pierces the dura and floats in CSF, occasionally masquerading as a tumor.

• Combined sequestration – Multiple free fragments dispersed at differing depths, producing erratic symptomatology.

Accurate typing guides surgical planning—central fragments may necessitate bilateral laminotomy, whereas foraminal pieces often need far-lateral approaches.

Causes of L4–L5 Disc Sequestration

1. Age-related disc degeneration – Progressive dehydration, loss of proteoglycan, and endplate sclerosis after age 30 weaken the annulus, allowing nucleus extrusion.

2. Repetitive flexion-rotation movements – Occupations requiring frequent trunk twisting (e.g., manual lifting, warehousing) raise annular strain beyond failure thresholds.

3. Single heavy lift with improper technique – Sudden intra-discal pressure spikes (to 15–20 atm) can rupture the posterior annulus in one explosive event.

4. High-energy axial trauma – Falls from height or vehicular accidents concentrate compressive force on the disc, especially when the spine is flexed.

5. Obesity – Each extra kilogram increases lumbar compressive load by roughly 4 kg; chronic overload drives degenerative delamination of annulus fibers.

6. Smoking – Nicotine induces vasoconstriction, lowers endplate perfusion, diminishes disc nutrition, and accelerates catabolic enzyme expression.

7. Genetic collagen defects – Polymorphisms in COL9A2, COL11A1, and aggrecan genes predispose to early annular fissuring.

8. Tall stature – Longer lever arms amplify bending moments across lumbar discs during forward flexion.

9. Sedentary lifestyle – Weak paraspinal and abdominal stabilizers allow micromotion and shear across segment, hastening annular tears.

10. Prolonged sitting or driving – Sustained flexion-relaxation posture elevates posterior annular pressure and diminishes disc perfusion.

11. Whole-body vibration exposure – Heavy-vehicle operators experience repetitive vertical shocks that fatigue annular collagen.

12. Pregnancy – Hormonal laxity (relaxin) and maternal weight gain increase lumbar load; nine percent of pregnancies show MRI evidence of new disc herniation.

13. Corticosteroid therapy – Long-term systemic steroids impair collagen synthesis and matrix repair, weakening disc structure.

14. Diabetes mellitus – Advanced glycation end-products cross-link disc proteins, stiffen the annulus, yet render it brittle and prone to rupture.

15. Inflammatory spondyloarthropathy – Chronic inflammation erodes endplates, destabilizing the disc; acute flares provoke extrusion.

16. Lumbar micro-instability – Spondylolisthesis or facet arthropathy subjects the disc to aberrant translational shear.

17. Congenital narrow canal – A tight canal leaves less epidural space, so a modest extrusion more easily shears free and migrates.

18. Previous disc surgery – Scar remodeling alters annular stress distribution; residual nuclei can extrude through weakened tissue.

19. Lumbar infection (spondylodiscitis) – Enzymatic destruction of annulus by bacteria or inflammation lowers tensile strength drastically.

20. Nutritional osteoporosis – Severe vitamin D or calcium deficiency weakens adjacent endplates and promotes disc height loss and tear propagation.

Each factor alone may not guarantee sequestration, but additive exposure synergistically undermines disc integrity until the posterior annulus tears and the nucleus fragment escapes.

 Common Symptoms

1. Deep low-back ache – A dull constant pain centered at the beltline, often worst after sitting, due to chemical irritation of pain fibers in the torn annulus.

2. Shooting leg pain (sciatica) – Electric-like jolts that follow the buttock, outer thigh, and top of the foot (L5 dermatome) when the sequestered piece compresses or inflames the L5 nerve root.

3. Tingling or numbness – Pins and needles or loss of feeling along the great-toe side of the foot as sensory fibers misfire or fall silent.

4. Burning calf pain – Irritation of small unmyelinated C-fibers causes a slow burning sensation radiating toward the ankle.

5. Foot drop – Weakness in ankle dorsiflexion and toe extension; patients may trip over the toes because motor axons to the extensor hallucis longus are strangled.

6. Pain on coughing or sneezing – Spikes of intrathecal pressure momentarily jam the fragment harder against the nerve root.

7. Morning stiffness – Overnight disc re-hydration enlarges the fragment’s mass, magnifying nerve contact when the patient first stands.

8. Difficulty straightening up – Reflex spasm of paraspinal muscles locks the lumbar spine in partial flexion to protect the injured segment.

9. Antalgic list – Patients lean their trunk to one side to widen the lateral recess and relieve pressure on the root.

10. Shortened walking tolerance – After a few hundred meters pain intensifies (neurogenic claudication-like) because repetitive motion inflames the root.

11. Unsteady gait – Proprioceptive loss and weak dorsiflexors make foot placement unsure, especially on stairs.

12. Loss of knee-jerk asymmetry – The patellar reflex may be diminished when motor fibers are chronically compressed.

13. Hamstring tightness – Reactive shortening of hamstrings limits hip flexion to protect the lumbar spine, perceived as tightness behind the thigh.

14. Muscle fasciculations – Occasional visible twitches in the anterior tibialis muscle reflect irritated motor axons firing ectopically.

15. Sleep disturbance – Rolling over in bed provokes stabbing pain, fracturing deep sleep and leaving patients exhausted.

16. Bowel or bladder urgency – Massive fragments may indent the thecal sac, irritating sacral roots that modulate pelvic organs.

17. Sexual dysfunction – Fear of pain and nerve involvement can hinder erection or cause dyspareunia.

18. Anxiety and irritability – Chronic, unpredictable pain undermines mood and resilience.

19. Reduced work capacity – Inability to lift, drive, or sit prolongs sick leave and fuels financial stress.

20. Overall quality-of-life loss – Activity curtailment, decreased social interaction, and dependence on analgesics create a downward health spiral.

Recognizing the full spectrum—not only sharp leg pain—helps clinicians link subtle complaints back to a hidden sequestered disc.

Diagnostic Tests and How Each One Helps

A. Physical Examination Techniques

1. Inspection & postural analysis – Observes trunk list, pelvic tilt, and scoliosis; a protective lean toward the healthy side implies a paracentral sequestered fragment.

2. Palpation of spinous processes and paraspinals – Localizes tenderness or protective muscle spasm over L4–L5.

3. Active lumbar range-of-motion testing – Flexion often increases leg pain as the fragment moves posteriorly; extension may relieve symptoms by shifting dura anteriorly.

4. Gait observation – Foot drop or high-stepping “steppage gait” betrays L5 motor deficit.

5. Neurological screen (motor, sensory, reflex) – Grading strength of toe extensors, mapping areas of numbness, and assessing the Achilles and patellar reflexes document objective deficits.

B. Provocative Manual Tests

6. Straight Leg Raise (SLR) – Raising the symptomatic leg while supine stretches the L5 root; reproduction of pain between 30° – 70° suggests root irritation by a sequestered fragment.

7. Crossed Straight Leg Raise – Pain in the opposite leg when the healthy limb is lifted is almost pathognomonic for a large medial fragment displacing dural structures.

8. Slump Test – Sequential flexion of spine, neck, and knee loads the neural tissue; leg pain indicates heightened mechanosensitivity of the compressed root.

9. Femoral Nerve Stretch Test – Less common at L4–L5 but checks higher-level fragments; prone knee flexion produces anterior thigh pain if L4 root involved.

10. Prone Instability Test – Detects segmental hyper-mobility; pain relieved when trunk muscles contract implies instability co-existing with disc injury.

C. Laboratory and Pathological Investigations

11. Complete Blood Count (CBC) – Screens for systemic infection mimicking discogenic pain; leukocytosis or anemia may shift differential.

12. Erythrocyte Sedimentation Rate (ESR) – Elevated ESR suggests spondylodiscitis or inflammatory spondyloarthropathy rather than purely mechanical sequestration.

13. C-reactive Protein (CRP) – Sensitive acute-phase reactant; normal CRP supports degenerative cause, high CRP prompts infection work-up.

14. HLA-B27 testing – Positive result raises suspicion for ankylosing spondylitis, where inflammatory processes can coexist with disc lesions.

15. Serum bone profile (calcium, phosphate, vitamin D) – Identifies osteomalacia or severe D-deficiency contributing to endplate fragility and disc collapse.

D. Electrodiagnostic Studies

16. Nerve Conduction Study (NCS) – Measures motor and sensory conduction velocity; slowed latency along the peroneal nerve supports L5 radiculopathy.

17. Electromyography (EMG) – Detects fibrillation potentials, positive sharp waves, and chronic reinnervation in L5-innervated muscles, pinpointing the neurosegmental level.

18. H-reflex testing – Although classically S1, absent or prolonged H-reflex in tibialis anterior can occasionally indicate L5 root entrapment by a sequestered disc.

19. F-wave latency analysis – Prolonged minimal F-wave latency highlights proximal motor root conduction block.

20. Somatosensory Evoked Potentials (SSEP) – Delayed cortical response after great-toe stimulation suggests demyelination or compression along the L5 pathway.

E. Imaging Modalities

21. Plain Lumbar X-ray – Demonstrates alignment, spondylolisthesis, disc height loss, or congenital narrowing, setting baseline context.

22. Magnetic Resonance Imaging (MRI) – Gold standard: T2-weighted images show high-signal nucleus fragment in the canal; contrast enhancement highlights inflammatory rim.

23. Gadolinium-enhanced MRI – Differentiates sequestered disc (peripheral enhancement) from epidural abscess or neoplasm (homogeneous interior enhancement).

24. MRI with axial and sagittal oblique cuts – Axial cuts identify direction (central vs paracentral), while sagittal obliques reveal cranio-caudal migration.

25. Upright or weight-bearing MRI – Unmasks dynamic stenosis; fragment position may shift inferiorly when loaded.

26. Computed Tomography (CT) Scan – Highlights calcified fragments and assesses bony canal dimensions when MRI contraindicated.

27. CT Myelography – Water-soluble contrast outlines nerve roots; abrupt cut-off indicates space-occupying fragment; useful after instrumented fusions where MRI artifact exists.

28. Dynamic Flexion-Extension X-rays – Detect segmental instability that might warrant fusion in addition to fragment removal.

29. Discography – Rarely used; pressurized injection provokes concordant pain and demonstrates annular tears but not sequestered fragments.

30. Bone Scintigraphy (Technetium-99m) – Hot uptake around L4–L5 suggests active inflammatory response or infection rather than a simple degenerative sequestration.

6. Pulsed Short-Wave Diathermy – Radio-frequency pulses heat deep tissues without burning the skin, promoting ligamentous elasticity.

7. Ultrasound Therapy – Microscopic vibration massaging soft tissues helps nutrient diffusion into the avascular disc.

8. Low-Level Laser Therapy (LLLT) – Photobiomodulation triggers ATP production and anti-inflammatory cytokines.

9. Spinal Traction (Mechanical or Manual) – Gentle pulling opens the L4-L5 foramen, temporarily reducing nerve-root compression.

10. Instrument-Assisted Soft-Tissue Mobilisation (IASTM) – Tools glide along fascia, breaking scars and improving flexibility.

11. McKenzie Mechanical Diagnosis & Therapy (MDT) Extension Sessions – Centralises leg pain by repeatedly loading the disc posteriorly.

12. Mulligan SNAGs (Sustained Natural Apophyseal Glides) – Therapist applies painless facet glides while you bend; may free stuck joints.

13. Kinesio-Taping – Elastic tape lifts skin microscopically, altering proprioception and bruising drainage.

14. Aquatic Hydrotherapy – Buoyancy unloads the spine so you strengthen core muscles without gravitational strain.

15. Shockwave Therapy (Radial/Focused) – Acoustic pulses stimulate local healing and pain-gate control.
