Lumbar Cartilaginous Endplate Corner Lesions

Lumbar cartilaginous endplate corner lesions are tiny areas of damage at the junction where each vertebral body meets its intervertebral disc, right at the front and back “corners” of the spine. Over time or after injury, the smooth cartilage that cushions the disc can crack, erode, or become inflamed. These lesions weaken the disc’s ability to absorb shock, leading to back pain and sometimes nerve irritation as the disc bulges unevenly. When seen on MRI, they often appear as small zones of high signal on T2-weighted images, reflecting fluid or inflammation under the endplate.

Types of Lumbar Cartilaginous Endplate Corner Lesions

1. Discal‐rim‐only lesions (Type A & B)
   Cawley et al. distinguished lesions confined to the discal surface of the vertebral rim—where the annulus fibrosus attaches to bone. In Type A, involvement is limited and subtle; in Type B, rim erosion is more extensive, but neither extends into the cartilaginous endplate proper Journal Cot.

2. Cartilaginous endplate lesions (Type C & D)
   Types C and D by Cawley refer to lesions that breach the cartilaginous endplate itself. Type C lesions are superficial cartilage defects, while Type D extends into the subchondral bone beneath the cartilage layer Journal Cot.

3. Combined rim and cartilaginous lesions (Type E)
   Type E lesions involve both the discal rim and the cartilaginous endplate in a single discovertebral lesion, often leading to pseudarthrosis in ankylosing spondylitis (the so‐called “Andersson lesion”) Journal Cot.

4. Inflammatory vs. structural corner lesions
   According to the ASAS MRI working group, corner lesions can be active (bone marrow edema at vertebral corners) or structural (fat deposition, erosion, sclerosis, syndesmophyte formation) Comum.

Non-Pharmacological Treatments

A. Physiotherapy & Electrotherapy

1. Manual Therapy
   Description: Hands-on mobilization by a trained therapist to gently glide or stretch spinal joints.
   Purpose: To restore normal joint movement, reduce stiffness, and ease pain.
   Mechanism: By applying controlled forces, manual therapy helps break up adhesions in the joint capsule and stimulates mechanoreceptors, reducing pain signals to the brain.

2. Spinal Mobilization
   Description: Low-grade oscillatory movements applied to restricted spinal segments.
   Purpose: To improve segmental mobility without causing muscle guarding.
   Mechanism: Repeated small oscillations promote fluid exchange in the joint, reduce synovial irritation, and normalize local nerve firing.

3. Soft-Tissue Mobilization
   Description: Therapist-applied pressure and kneading to muscles and fascia around the lumbar spine.
   Purpose: To release muscle knots, improve circulation, and reduce pain.
   Mechanism: Mechanical pressure breaks up myofascial adhesions, enhances local blood flow, and stimulates large sensory fibers that inhibit pain transmission.

4. Myofascial Release
   Description: Sustained pressure on tight fascial bands around the spine.
   Purpose: To lengthen and soften fascia, improving spinal mechanics.
   Mechanism: Slow, steady stretch signals fibroblasts to remodel collagen, reducing fascial tension and associated pain.

5. Dry Needling
   Description: Insertion of thin filiform needles into trigger points in paraspinal muscles.
   Purpose: To deactivate painful trigger points and restore muscle function.
   Mechanism: Needle insertion disrupts dysfunctional endplates in muscle fibers, causing a twitch response that resets pain thresholds.

6. Heat Therapy
   Description: Application of hot packs or heat wraps to the lumbar area.
   Purpose: To ease muscle spasm and increase tissue extensibility.
   Mechanism: Heat dilates blood vessels, improving oxygen and nutrient delivery while reducing muscle spindle sensitivity.

7. Cold Therapy
   Description: Use of ice packs or cold compresses on painful spots.
   Purpose: To numb pain and reduce local swelling after acute flare-ups.
   Mechanism: Cold constricts blood vessels and slows nerve conduction, blocking pain signals.

8. Transcutaneous Electrical Nerve Stimulation (TENS)
   Description: Low-voltage electrical pulses delivered through skin electrodes.
   Purpose: To modulate pain by “closing the gate” in spinal cord pathways.
   Mechanism: Stimulates large-diameter Aβ nerve fibers, which inhibit transmission of pain via smaller Aδ and C fibers.

9. Interferential Current Therapy
   Description: Two medium-frequency currents that intersect in the lumbar tissues.
   Purpose: For deeper analgesia and reduced muscle spasm than TENS.
   Mechanism: Crossing currents create a low-frequency “beat” that penetrates deeply, activating endogenous opioid release.

13. Mechanical Traction
    Description: Gradual pulling force applied along the spine’s axis.
    Purpose: To decompress intervertebral discs and reduce nerve root impingement.
    Mechanism: Traction opens disc spaces, lowers intradiscal pressure, and retracts herniated material.

14. Hydrotherapy
    Description: Exercises and therapy performed in warm water.
    Purpose: To offload joints, improve mobility, and reduce pain.

    Purpose: To support muscles without restricting range of motion.
    Mechanism: Tape lifts skin microscopically, improving lymphatic flow and reducing nociceptor sensitivity.

B. Exercise Therapies

16. Core Stabilization Exercises
    Core stabilization focuses on strengthening the deep “corset” muscles—transverse abdominis and multifidus—to support the lumbar spine. The purpose is to improve spinal alignment during movement. Mechanistically, contracting these muscles increases intra-abdominal pressure and stabilizes vertebral segments, reducing stress on damaged endplates.

17. McKenzie Extension Protocol
    This sequence of prone-lying and repeated lumbar extensions teaches the spine to centralize pain away from the corners. Its purpose is to retract bulging discs and relieve nerve irritation. Mechanism: end-range extension shifts nucleus pulposus material away from the posterior corners, alleviating pressure on lesions.

18. Flexibility (Hamstring & Hip Stretching)
    Tight hamstrings and hip flexors pull on the pelvis, increasing lumbar stress. Stretching these muscles improves pelvic alignment. Mechanically, elongating the muscle-tendon units reduces anterior pelvic tilt, unloading endplate corners.

Prevention Strategies

1. Maintain Neutral Spine Posture
   Keeping the back straight when sitting or standing spreads load evenly across vertebrae, protecting endplates from corner stress.

2. Strengthen Core Muscles
   A strong “corset” of abs and back muscles absorbs shock and stabilizes the spine, reducing microtrauma to lesions.

3. Use Proper Lifting Technique
   Bend at the hips and knees, not the waist, and keep objects close to your body to minimize lever forces on the lumbar corners.

4. Manage Body Weight
   Each extra pound increases spinal load by roughly three times—losing weight offloads discs and preserves cartilage health.

5. Ergonomic Workstation Setup
   Adjust chair height, monitor level, and keyboard position to avoid sustained forward flexion or twisting that accelerates lesion formation.

6. Stay Active with Low-Impact Cardio
   Regular walking or swimming keeps discs hydrated and resilient, preventing breakdown at the corners.

7. Quit Smoking
   Smoking impairs blood flow to spinal tissues, delaying repair and increasing degeneration risk.

8. Ensure Adequate Vitamin D & Calcium
   Strong vertebral bodies are less prone to microfractures and resultant endplate lesions.

9. Avoid Prolonged Static Postures
   Move or change position every 30–45 minutes to prevent focal overload on endplates.

10. Incorporate Mind-Body Stress Management
    High stress increases muscle tension and inflammation; techniques like meditation protect discs and endplates.

When to See a Doctor

Seek medical evaluation if you experience any of the following: persistent back pain unrelieved by rest and simple measures after two weeks; numbness or tingling that travels down the legs; significant weakness or changes in walking; loss of bladder or bowel control; fever or unexplained weight loss with back pain; or severe pain following trauma. Early diagnosis—through physical exam, lab tests to rule out infection or autoimmune causes, and MRI imaging—allows timely treatment before irreversible damage occurs.

What to Do & What to Avoid

1. Do maintain regular core and flexibility exercises. Avoid sitting for longer than 45 minutes without a break.

2. Do apply heat packs before activity. Avoid cold packs if you have chronic stiffness (use for acute flare-ups only).

3. Do use a lumbar roll or supportive chair. Avoid slouching or “C-shaped” spinal postures.

4. Do lift with your legs and keep loads light. Avoid twisting while lifting.

5. Do walk daily for 20–30 minutes. Avoid high-impact sports (e.g., running on hard surfaces) when in pain.

6. Do practice deep-breathing or meditation to lower muscle tension. Avoid excessive caffeine or stimulants that increase muscle tightness.

7. Do follow up with your physical therapist per schedule. Avoid skipping therapy sessions even when feeling better.

8. Do wear supportive, low-heeled shoes. Avoid extreme high heels or completely flat soles.

9. Do stay hydrated to keep discs well-lubricated. Avoid sugary drinks that can worsen inflammation.

10. Do use over-the-counter NSAIDs as directed for flares. Avoid relying on opioids for more than a few days.

Frequently Asked Questions

1. What causes endplate corner lesions?
   Repeated microtrauma from poor posture, age-related degeneration, or a sudden overload can crack the cartilage and subchondral bone at the disc margins.

2. Are these lesions reversible?
   Early lesions with inflammation can heal with proper offloading and nutrition; chronic fissures may scar but often remain symptom-free if stabilized.

3. Will an MRI always show them?
   High-resolution T2-weighted and STIR sequences best highlight fluid in acute lesions; chronic sclerotic corners may appear as low-signal on all sequences.

4. Can non-surgical treatments really help?
   Yes—studies show that combined physiotherapy, exercise, education, and appropriate medications can resolve pain in over 80 % of cases.

5. Is surgery ever required?
   Only when lesions cause nerve compression unresponsive to conservative care, or when they lead to spinal instability best treated with fusion or disc replacement.

6. How long does it take to recover?
   Mild cases often improve in 6–8 weeks; more severe lesions may need 3–6 months of rehab before returning to full activity.

7. Can I prevent future lesions?
   Absolutely—core strengthening, ergonomic habits, weight control, and quitting smoking dramatically lower risk.

8. Are supplements worth taking?
   Many patients find glucosamine, chondroitin, and omega-3 helpful; these support cartilage repair, though individual responses vary.

9. Will bisphosphonates help?
   In patients with low bone density, bisphosphonates can reduce microfracture risk, indirectly protecting endplates.

10. Is PRP injection painful?
    It can cause mild soreness for 24–48 hours but generally reduces pain over ensuing weeks by accelerating healing.

11. Does traction really work?
    For some patients, intermittent traction eases nerve root pressure; its benefit is greatest when combined with exercise.

12. Are there lifestyle changes I must make?
    Yes—ergonomic workstations, regular movement breaks, and stress management are cornerstones of long-term relief.

13. When should I stop exercising?
    Stop any exercise that causes sharp worsening of pain, numbness, or weakness—gently modify rather than push through.

14. Can yoga worsen the lesion?
    Only if you force deep backbends or twists prematurely; gentle, guided practice focusing on alignment is safe.

15. How often should I follow up?
    Regular check-ins every 4–6 weeks during active rehab, then every 3–6 months to ensure maintenance of spine health.
