Lumbar Posterior Disc Prolapse

A lumbar posterior disc prolapse—often called a herniated or slipped disc—occurs when the soft inner gel (nucleus pulposus) of an intervertebral disc in your lower back pushes through a tear in its tough outer ring (annulus fibrosus) toward the spinal canal. This bulging material can press on nearby nerves, causing pain, numbness, or weakness in your back, buttocks, legs, or feet.

Lumbar posterior disc prolapse—commonly called a herniated or slipped disc—occurs when the soft inner gel (nucleus pulposus) of an intervertebral disc pushes through a tear in its tougher outer ring (annulus fibrosus) toward the spinal canal at the lumbar (lower back) level. When that gel bulges or extrudes posteriorly—toward the back—it can press on spinal nerves or the spinal cord itself, causing pain, numbness, or weakness. This condition is most common between the L4–L5 and L5–S1 vertebral levels, where spinal load and mobility are greatest.

Anatomy of the Lumbar Intervertebral Disc

Structure

The intervertebral disc is a fibrocartilaginous pad sandwiched between adjacent lumbar vertebral bodies. It consists of two main parts: the nucleus pulposus—a gelatinous core rich in water and proteoglycans—and the annulus fibrosus—a laminated, tough outer ring of collagen fibers arranged in concentric lamellae. This dual-layer arrangement provides both flexibility and strength, allowing discs to absorb shocks while maintaining spinal stability.

Location

Lumbar intervertebral discs lie between the vertebral bodies of L1 through L5 and the sacrum (S1). They occupy the anterior segment of the vertebral column, posterior to the abdominal organs, and just in front of the spinal canal. Their position between each pair of vertebrae gives them a central role in load transmission and spinal mobility across the lower back.

Origin

Although “origin” is usually a term applied to muscles, here it refers to where the disc’s fibers begin: the outer lamellae of the annulus fibrosus anchor into the ring apophysis at the periphery of each vertebral endplate. In this way, each disc “originates” from the superior vertebral body’s cartilage endplate, where the annular fibers integrate with bone and cartilage.

Insertion

Similarly, the annulus fibrosus “inserts” on the inferior vertebral body’s cartilage endplate. Its concentric collagen layers attach firmly to the bone of the lower vertebra’s endplate, completing a firm ring that encircles the nucleus pulposus and resists internal pressure.

Blood Supply

Intervertebral discs are largely avascular in their central zones; they receive nourishment by diffusion. The outer annulus fibrosus is supplied by small branches of the lumbar segmental arteries—primarily the ascending lumbar artery and its radicular branches—which penetrate the outer one-third of the annulus. Nutrient exchange then diffuses inward through the cartilage endplates, sustaining the disc’s inner layers.

Nerve Supply

Sensory nerve fibers—mainly small nociceptive (pain) fibers—innervate only the outer third of the annulus fibrosus. These fibers arise from the sinuvertebral (recurrent meningeal) nerve, a branch of the spinal nerve. When the annulus tears or the nucleus herniates, these pain fibers become stimulated, producing the characteristic discogenic back pain.

Functions

1. Shock Absorption: The gelatinous nucleus pulposus acts like a fluid cushion, absorbing compressive forces when you walk, run, or lift, thereby protecting bony vertebrae from impact damage.

2. Load Distribution: The annulus fibrosus redistributes loads evenly across the disc surface, preventing stress concentrations and potential endplate fractures.

3. Spinal Flexibility: Discs permit small motions in multiple planes—flexion, extension, lateral bending, and rotation—enabling the lumbar spine’s range of motion.

4. Maintain Intervertebral Height: By resisting compression, discs keep the vertebral bodies a consistent distance apart; this spacing preserves foraminal height so nerve roots can exit unimpeded.

5. Protect Neural Elements: The combination of disc height and firmness forms a protective buffer in front of the spinal cord and nerve roots, preventing direct bone-nerve contact.

6. Spinal Alignment: Discs contribute to the natural lumbar lordosis (inward curve), maintaining proper spinal biomechanics and posture under loads.

Types of Lumbar Posterior Disc Prolapse

1. Bulging Disc
   A generalized extension of the annulus fibrosus beyond its normal perimeter without a focal tear. The disc maintains continuity of all annular fibers, but the outer ring balloons outward. Bulges often involve over 25% of the disc circumference and can be asymptomatic or cause mild discomfort.

2. Protruded Disc (Contained Herniation)
   A focal herniation in which the nucleus pulposus pushes into the annulus fibrosus, creating a focal “bump,” but remains contained by some intact annular fibers. Protrusions occupy under 25% of the disc circumference and may press on nearby nerve roots.

3. Extruded Disc (Non-contained Herniation)
   Here, the nucleus pulposus breaks through the annulus fibrosus but remains attached to the disc. The herniated material extends beyond the disc space and can more significantly compress neural structures, often causing radicular pain.

4. Sequestered Disc (Free Fragment)
   In the most severe form, a fragment of nucleus pulposus completely separates from the parent disc and migrates into the spinal canal. This free fragment can produce acute, severe symptoms and often requires surgical removal.

5. Central Posterior Herniation
   The herniation pushes directly backward into the central spinal canal, potentially compressing the cauda equina. Central herniations can lead to bilateral symptoms or, in severe cases, cauda equina syndrome.

6. Paracentral Posterior Herniation
   The herniated disc material shifts slightly off-center but still pushes into the posterior canal. Paracentral herniations most commonly impinge one of the traversing nerve roots (e.g., an L5–S1 paracentral herniation irritates the S1 root).

7. Foraminal (Lateral) Herniation
   Disc material protrudes into the neural foramen—the exit zone of the nerve root. Foraminal herniations compress the exiting nerve root at the same level (e.g., an L4–L5 foraminal herniation compresses the L4 root).

8. Far Lateral (Extraforaminal) Herniation
   The herniation extends beyond the neural foramen into the extraforaminal region where the nerve root traverses laterally. These are less common but often cause intense radicular pain because they compress the root from outside its usual canal.

Causes of Lumbar Posterior Disc Prolapse

1. Age-related Degeneration
   With aging, the water content in the nucleus pulposus diminishes and proteoglycan levels fall. This loss of hydration and elasticity weakens the annulus fibrosus, making it prone to tears and herniation under normal loads.

2. Repetitive Lifting
   Bending forward and lifting heavy objects repeatedly places high compressive and shear forces on lumbar discs, especially when proper lifting mechanics are not used. Over time, micro-trauma accumulates and can precipitate annular failure.

3. Sudden Trauma
   A single high-force event—such as a fall, car accident, or heavy lift—can create enough intradiscal pressure to rupture the annulus fibrosus acutely, causing an immediate disc prolapse.

4. Poor Posture
   Chronic slouching or sustained forward flexion increases intradiscal pressure disproportionately on the anterior and posterior walls, accelerating annular fiber fatigue and eventual tearing.

5. Obesity
   Excess body weight elevates axial load on the lumbar spine. Discs bear this extra weight constantly, which over time contributes to degeneration and raises the risk of herniation.

6. Smoking
   Nicotine impairs blood flow to vertebral endplates and reduces disc nutrition, accelerating degenerative changes and diminishing the disc’s capacity to repair micro-tears.

7. Genetic Predisposition
   Certain genetic variants—particularly those affecting collagen production in the annulus fibrosus—have been linked to early disc degeneration and a higher incidence of herniation.

8. Sedentary Lifestyle
   Lack of regular movement and core muscle weakness reduce spinal support and lead to uneven load distribution, fostering disc wear and tear.

9. Occupational Vibrations
   Continuous exposure to whole-body vibration (e.g., in truck drivers or heavy machinery operators) causes microtrauma to spinal structures, including accelerated disc degeneration.

10. High-Impact Sports
    Activities like weightlifting, gymnastics, and contact sports can subject the lumbar spine to repetitive high forces, increasing the risk of acute or chronic disc injury.

11. Pregnancy
    Hormonal changes (relaxin) and increased abdominal weight shift biomechanics, raising lumbar load and sometimes precipitating disc dysfunction or herniation.

12. Congenital Spine Abnormalities
    Conditions such as scoliosis, spina bifida occulta, or transitional vertebrae alter normal biomechanics, putting abnormal stresses on adjacent discs.

13. Previous Spinal Surgery
    Surgery can destabilize spinal segments or change load patterns, which may accelerate degeneration at adjacent levels—a phenomenon known as adjacent segment disease.

14. Inflammatory Arthropathies
    Diseases like ankylosing spondylitis or rheumatoid arthritis can involve the spine, weakening disc-vertebra connections and promoting herniation.

15. Tumors or Infection
    Space-occupying lesions (metastases) or spinal infections (discitis) can compromise disc integrity or alter mechanical loading, indirectly causing prolapse.

16. Poor Nutrition
    Insufficient intake of key nutrients—vitamin C, collagen precursors, and matrix-building amino acids—can impair disc repair and resilience.

17. Hormonal Factors
    Hormonal imbalances affecting estrogen or cortisol may influence matrix metabolism, potentially weakening disc structure.

18. Overweight in Early Adulthood
    Adolescents and young adults carrying excess body mass may begin disc wear earlier, increasing lifetime risk of prolapse.

19. Foot Biomechanics Abnormalities
    Flat feet or overpronation change gait mechanics, transmitting abnormal loads up the kinetic chain to the lumbar discs.

20. Stress and Muscle Tension
    Chronic stress triggers muscle guarding and increased paraspinal muscle tension, which unevenly compresses discs and fosters micro-tearing.

Symptoms of Lumbar Posterior Disc Prolapse

1. Localized Lower Back Pain
   A constant or intermittent ache in the lumbar region, often aggravated by sitting, bending, or lifting, results from annular fiber irritation and local inflammation.

2. Radiating Leg Pain (Sciatica)
   Sharp, shooting pain that travels down one or both legs along the path of the sciatic nerve, typically indicating nerve root compression at L4–L5 or L5–S1 levels.

3. Numbness or Tingling
   Loss of sensation or “pins and needles” in the buttocks, thigh, calf, or foot arises when herniated material presses on sensory nerve fibers.

4. Muscle Weakness
   Compression of motor nerve roots can cause weakness in muscles like the tibialis anterior (foot dorsiflexion) or gastrocnemius (plantarflexion), leading to foot drop or shuffling gait.

5. Reflex Changes
   Diminished or absent deep tendon reflexes—such as the patellar (L4) or Achilles (S1)—signal involvement of specific spinal segments.

6. Pain with Coughing or Sneezing
   Sudden increases in intrathecal pressure during Valsalva maneuvers transiently expand the herniation, intensifying nerve compression and pain.

7. Aggravation on Forward Flexion
   Activities that bend the spine forward—like tying shoes or picking up objects—place additional pressure on the posterior disc, worsening discomfort.

8. Relief on Standing or Walking
   Upright posture opens the neural foramina and reduces posterior disc stress, often easing radicular pain compared to sitting or bending.

9. Muscle Spasm
   Paraspinal or iliopsoas muscle tightness and protective spasm occur reflexively to stabilize the painful segment.

10. Decreased Range of Motion
    Pain and muscle guarding limit flexion, extension, and lateral bending, resulting in a stiff, guarded posture.

11. Postural Abnormalities
    Antalgic lean or swayback posture may develop as the patient shifts weight away from the painful side to reduce disc pressure.

12. Nocturnal Pain
    Discomfort that wakes the patient at night often reflects increased inflammatory mediators accumulating around the herniation in recumbency.

13. Sensory Loss in Dermatomal Pattern
    Numbness or diminished light touch following a specific dermatome (e.g., L5 dermatome on the dorsum of the foot) indicates nerve root involvement.

14. Motor Deficits in Myotomal Distribution
    Weakness in a pattern corresponding to a particular nerve root (e.g., difficulty toe walking for S1) confirms functional impairment.

15. Positive Straight Leg Raise
    Radiating leg pain during passive elevation of the extended leg reproduces nerve tension, a hallmark of nerve root compression.

16. Positive Crossed Straight Leg Raise
    Pain in one leg when the opposite leg is raised suggests a large or central herniation affecting both sides.

17. Bowel or Bladder Dysfunction
    Urinary retention, incontinence, or saddle anesthesia are red flags for cauda equina syndrome and require emergency attention.

18. Sexual Dysfunction
    Impaired sensation or reflexes in the genital region may occur if sacral nerve roots (S2–S4) are compressed.

19. Gait Disturbance
    Difficulty heel-walking or toe-walking, wide-based gait, or foot drop reflect motor deficits from nerve root compression.

20. Muscle Atrophy
    Chronic compression may lead to wasting of muscles over weeks to months, especially in the calves or foot intrinsic muscles.

Diagnostic Tests

A. Physical Examination

1. Inspection
   Observe the patient’s posture, spinal alignment, and any antalgic lean. Look for decreased lumbar lordosis or a list (lateral shift), which often accompanies large herniations.

2. Palpation
   Gently press along the paraspinal muscles and spinous processes to identify localized tenderness, muscle spasm, or trigger points that localize the symptomatic segment.

3. Range of Motion Assessment
   Actively or passively move the lumbar spine through flexion, extension, lateral bending, and rotation to quantify motion loss and reproduce pain patterns.

4. Gait Analysis
   Ask the patient to walk on toes and heels; observe for foot drop or diminished push-off, which indicates specific nerve root motor deficits.

5. Posture Evaluation
   Assess spinal curves in standing and sitting—forward flexion may exaggerate a kyphotic posture, while extension may normalize it, providing diagnostic clues.

---

B. Manual (Provocative) Tests

6. Straight Leg Raise (Lasegue’s Test)
   With the patient supine and leg extended, passively raise the leg. Pain radiating below the knee between 30° and 70° elevation suggests L4–S1 nerve root tension from a posterior herniation.

7. Crossed Straight Leg Raise
   Lifting the asymptomatic leg reproduces pain in the affected leg; this finding is highly specific for a large central or paracentral herniation.

8. Slump Test
   With the patient seated, slump the spine, flex the neck, and extend the knee. Reproduction of leg pain under tension confirms neural involvement.

9. Bowstring Test
   After a positive straight leg raise, flex the knee slightly until pain lessens, then press the popliteal fossa to reproduce radicular pain, confirming sciatic nerve tension.

10. Kernig’s Sign
    With hip and knee flexed, extend the knee. Resistance or pain in the lumbar region or leg indicates meningeal or nerve root irritation.

11. Femoral Nerve Stretch Test
    In prone position, flex the knee to stretch the femoral nerve. Anterior thigh pain suggests L2–L4 root involvement, as in high lumbar herniations.

12. Milgram’s Test
    Ask the patient to lift both legs a few inches off the table and hold. Increased low back pain indicates raised intrathecal pressure from a herniation.

13. Kemp’s Test
    With the patient standing, extend and rotate the spine toward the symptomatic side. Local or radiating pain suggests facet or foraminal nerve root impingement.

14. Valsalva Maneuver
    Have the patient bear down as if having a bowel movement. If this increases back or leg pain, it implies intraspinal space-occupying pathology such as a herniation.

15. Neri’s Sign
    Passive flexion of one hip produces flexion of the opposite knee (“Bow sign”), indicating nerve root tension from a large disc protrusion.

---

C. Lab and Pathological Tests

16. Complete Blood Count (CBC)
    Although typically normal in disc herniation, CBC rules out infection if discitis is suspected; an elevated white blood cell count may signal inflammation or infection.

17. Erythrocyte Sedimentation Rate (ESR)
    A high ESR suggests systemic inflammation or infection (e.g., spinal osteomyelitis) rather than a pure mechanical herniation.

18. C-Reactive Protein (CRP)
    Like ESR, elevated CRP supports an inflammatory or infectious process; normal CRP helps exclude discitis or spondylodiscitis.

19. Rheumatoid Factor (RF) and ANA
    In patients with multisystem symptoms, these autoimmune markers help rule out inflammatory arthropathies that can mimic discogenic pain.

20. Blood Cultures
    If fever or systemic signs accompany back pain, cultures identify pathogens in suspected spinal infections requiring urgent antibiotic therapy.

---

D. Electrodiagnostic Tests

21. Electromyography (EMG)
    Needle electrodes detect denervation potentials in muscles innervated by affected roots, confirming chronic or acute nerve root irritation.

22. Nerve Conduction Velocity (Sensory)
    Measures how fast sensory signals travel; slowing indicates demyelination or compression along the nerve, as seen in herniation.

23. Motor Nerve Conduction Study
    Tests conduction along motor fibers; prolonged latencies or reduced amplitudes point to axonal injury from root compression.

24. F-Wave Studies
    F-waves examine proximal nerve segments and roots; abnormal F-wave persistence or latency suggests root involvement above the recording site.

25. H-Reflex Testing
    Primarily assesses S1 nerve root function; absent or delayed H-reflex supports S1 compression from an L5–S1 herniation.

---

E. Imaging Tests

26. Plain Radiography (X-ray)
    Although discs themselves are radiolucent, X-rays exclude fractures, spondylolisthesis, or gross instabilities that may accompany or mimic disc pathology.

27. Computed Tomography (CT) Scan
    Offers excellent bone detail and can visualize calcified herniations. CT myelography—injecting contrast into the spinal canal—enhances nerve root visualization if MRI is contraindicated.

28. Magnetic Resonance Imaging (MRI)
    The gold standard for disc evaluation: high-resolution images show annular tears, nucleus extrusion, nerve root compression, and associated inflammatory changes without radiation.

29. CT Myelography
    Combines CT resolution with intrathecal contrast to outline the thecal sac; especially useful in patients with pacemakers or metallic implants who cannot undergo MRI.

30. Discography
    Involves injecting contrast into the disc under fluoroscopy to reproduce pain and visualize internal tears. Used selectively when symptoms don’t match imaging or before surgery.

Surgical Options

When conservative measures fail, these procedures may be offered. Each procedure description and main benefit:

1. Microdiscectomy

   • Procedure: Small incision; remove the herniated fragment compressing the nerve.

   • Benefits: Quick relief of leg pain with minimal tissue damage.

2. Laminectomy

   • Procedure: Removal of part of the vertebral arch (lamina) to increase canal space.

   • Benefits: Decompresses nerves in multilevel disease.

3. Open Discectomy

   • Procedure: Larger incision to remove disc material and, if needed, part of the bone.

   • Benefits: Direct visualization allows thorough decompression.

4. Lumbar Fusion (PLIF/TLIF)

   • Procedure: Remove disc, insert bone graft and hardware to fuse vertebrae.

   • Benefits: Stabilizes spine, prevents further slippage.

5. Endoscopic Discectomy

   • Procedure: Keyhole incision; endoscope used to extract disc material.

   • Benefits: Less muscle trauma, faster recovery.

6. Percutaneous Discectomy

   • Procedure: Needle-based removal of disc fragments under imaging guidance.

   • Benefits: Minimally invasive, outpatient basis.

7. Chemonucleolysis

   • Procedure: Enzyme injection (chymopapain) to dissolve disc nucleus.

   • Benefits: Non-surgical chemical reduction of disc bulge.

8. Artificial Disc Replacement

   • Procedure: Remove the damaged disc and replace it with a prosthetic.

   • Benefits: Maintains segmental motion and reduces adjacent stress.

9. Microendoscopic Discectomy

   • Procedure: Endoscope-assisted microsurgery with tubular retractors.

   • Benefits: Reduced blood loss and postoperative pain.

10. Spinal Fusion with Pedicle Screws

    • Procedure: Fusion augmented with screws and rods for added stability.

    • Benefits: Strong fixation for severe instability.

When to See a Doctor

Contact a healthcare professional if you experience:

• Severe or worsening back and leg pain that limits daily activities

• Numbness, tingling, or weakness in your legs or feet

• Loss of bladder or bowel control (medical emergency)

• Fever or unexplained weight loss with back pain

• No improvement after 6 weeks of conservative care

Frequently Asked Questions

1. What exactly causes a lumbar disc to prolapse?
   Repeated strain, age-related “wear and tear,” sudden heavy lifting, or twisting movements can tear the disc’s outer layer, letting the inner gel push backward.

2. What are the common symptoms?
   Low back pain, sciatica (shooting leg pain), numbness, tingling, muscle weakness, and sometimes loss of reflexes in the knee or ankle.

3. How is it diagnosed?
   Your doctor uses your history, physical exam, and imaging (MRI is gold standard) to confirm the disc bulge and nerve involvement.

4. Can a herniated disc heal on its own?
   Yes—up to 90% improve with non-surgical care over 6–12 weeks as inflammation subsides and the disc shrinks.

5. Which non-surgical treatments work best?
   A combination of exercise (especially extension and core work), manual therapy, and patient education yields the best outcomes.

6. When is surgery recommended?
   If you have severe pain unrelieved by 6–12 weeks of care, progressive neurological deficits, or red-flag signs (e.g., bowel/bladder loss).

7. How long is recovery after microdiscectomy?
   Most people resume light activities in 2–4 weeks and return to normal life by 6–12 weeks.

8. Are spinal injections safe?
   Epidural steroid injections and PRP are generally safe when done by experienced providers; minor bleeding or infection is rare.

9. Will my job affect recovery?
   Jobs involving heavy lifting or prolonged sitting may require modified duties until you rebuild strength and flexibility.

10. Can I exercise with a herniated disc?
    Yes—guided, low-impact exercises that avoid bending or twisting excessively are encouraged soon after diagnosis.

11. Is prolonged bed rest ever advised?
    No—extended rest can worsen stiffness and slow healing. Short rest for 1–2 days is acceptable, then gradual movement is key.

12. Can diet changes help?
    A balanced diet rich in anti-inflammatory foods (fruits, vegetables, omega-3s) supports healing but cannot reverse a herniation by itself.

13. What’s the chance of recurrence?
    Up to 5–15% may have a second herniation at the same level; preventive exercises and lifestyle changes lower that risk.

14. Does smoking affect healing?
    Yes—smoking reduces blood flow to discs, delaying recovery and increasing recurrence risk.

15. Can children get lumbar disc prolapse?
    Rarely—most cases occur in adults aged 30–50 due to disc degeneration over time.
