Thoracic Disc Backward Slip at T5–T6

A thoracic disc backward slip—also called a posterior thoracic disc displacement—occurs when the intervertebral disc material between the fifth (T5) and sixth (T6) thoracic vertebrae shifts posteriorly into the spinal canal. In healthy anatomy, each disc sits snugly between vertebral bodies, with the tough outer annulus fibrosus containing the soft, gelatinous nucleus pulposus. A backward slip means that part of the nucleus (and sometimes annulus fragments) pushes beyond the normal disc boundary toward the spinal cord or nerve roots, potentially compressing neural structures and causing pain, numbness, or weakness below the level of injury radiopaedia.org.

Thoracic disc herniations and backward slips are rare—accounting for less than 1% of all spinal disc problems—because the thoracic region is more rigid due to the rib attachments and narrower discs radiopaedia.orgorthobullets.com. However, when they do occur, they can cause mid-back pain, radicular symptoms along the chest wall, gait disturbances, and even myelopathy (spinal cord dysfunction) if significant compression develops.

Thoracic retrolisthesis at T5–T6—often called a “backward slip” of the T5 vertebral body on T6—is a form of retrospondylolisthesis in the middle portion of the spine. In this condition, the T5 vertebra is displaced posteriorly relative to T6 by at least 2 mm but without frank dislocation. Even small degrees of slip can disrupt normal spinal alignment, overload the intervertebral disc, irritate nerves, and provoke degenerative changes over time en.wikipedia.orgradiopaedia.org.

Retrolistheses occur most commonly in the cervical and lumbar regions but can affect the thoracic spine, where they may compromise rib mobility, chest wall mechanics, and—in more severe cases—the spinal cord itself en.wikipedia.org. At T5–T6, such a backward slip can manifest as mid-back pain, focal stiffness, intercostal nerve irritation, and in advanced cases, myelopathic signs below the level of pathology.

Types of Thoracic Retrolisthesis

Retrolistheses are classified both by etiology (cause) and by morphology (how the vertebra lies relative to its neighbors). At T5–T6, the main types include:

1. Degenerative Retrolisthesis
   Occurs due to age-related wear and tear on the disc, facet joints, and ligaments, leading to loss of stability and posterior vertebral drift en.wikipedia.orgdrtonynalda.com.

2. Isthmic Retrolisthesis
   Results from a defect or stress fracture in the pars interarticularis, allowing the vertebral body to slip backward over the segment below radiologykey.com.

3. Congenital (Dysplastic) Retrolisthesis
   Arises from developmental anomalies of the vertebral arch or facet joints, predisposing the spine to posterior displacement even without degenerative changes radiopaedia.orghealthline.com.

4. Traumatic Retrolisthesis
   Caused by acute injuries—such as vertebral fractures or ligament tears from falls or high-impact trauma—that destabilize the T5–T6 segment, permitting backward slip radiopaedia.org.

5. Pathological Retrolisthesis
   Occurs when bone-weakening conditions (e.g., primary bone tumors or metastases) undermine vertebral integrity, allowing slippage under normal loads radiologykey.com.

6. Iatrogenic Retrolisthesis
   Develops as an unintended consequence of prior spinal surgery (e.g., laminectomy or fusion) that alters mechanics and stability at adjacent levels radiologykey.com.

7. Complete Retrolisthesis
   The T5 vertebral body lies entirely posterior to both T4 above and T6 below, indicating maximum posterior displacement en.wikipedia.org.

8. Stairstepped Retrolisthesis
   The T5 body is posterior to T4 but anterior to T6, creating a “step”-like alignment on lateral imaging en.wikipedia.org.

9. Partial Retrolisthesis
   The T5 body is displaced posteriorly relative to either the vertebra above (T4) or below (T6), but not both en.wikipedia.org.

   • Mechanism: Platelet cytokines stimulate local tissue regeneration and angiogenesis.

4. Autologous Mesenchymal Stem Cell (MSC) Therapy

   • Dosage: 1–10 million cells per injection

   • Function: Potential disc regeneration.

   • Mechanism: MSCs differentiate into nucleus-like cells and secrete trophic factors.

5. Hyaluronic Acid (Viscosupplementation)

   • Dosage: 50 mg via intradiscal or facet joint injection

   • Function: Improve joint lubrication and reduce friction.

   • Mechanism: Increases synovial fluid viscosity and cushions load-bearing surfaces.

6. Collagenase Injection

   • Dosage: 0.25 mg into herniated disc (investigational)

   • Function: Enzymatic reduction of herniated tissue bulk.

   • Mechanism: Degrades extruded nucleus pulposus collagen fibers to decompress nerve roots.

7. Recombinant Human Growth Factor (rhFGF-18)

   • Dosage: Under clinical trial protocols

   • Function: Stimulate matrix synthesis.

   • Mechanism: Binds fibroblast receptors, increasing proteoglycan and collagen production.

8. Mesenchymal Stromal Cell-Derived Exosomes

   • Dosage: Experimental doses in phase I/II trials

   • Function: Paracrine regenerative signaling.

   • Mechanism: Deliver microRNAs and growth factors to modulate inflammation and repair.

9. Adipose-Derived Stem Cell (ASC) Injection

   • Dosage: 5–10 million cells intradiscally

   • Function: Promote disc cell viability.

   • Mechanism: ASCs release trophic factors that reduce apoptosis and enhance matrix formation.

10. Platelet Lysate

• Dosage: 2–4 mL at peridiscal site

• Function: Anti-inflammatory and regenerative support.

• Mechanism: Growth factor mix from platelets enhances cell proliferation and reduces cytokine activity.

(Most regenerative approaches remain investigational; patient selection and specialized protocols are critical.)

Surgical Options (Procedures)

Surgery is reserved for patients with intractable pain, progressive neurological deficits, or myelopathy.

1. Transforaminal Endoscopic Discectomy (TESSYS Method)

   • Procedure: Minimally invasive endoscopic removal of herniated disc via Kambin’s Triangle.

   • Benefits: Local anesthesia, small incision, less muscle disruption, quicker recovery en.wikipedia.org.

2. Video-Assisted Thoracoscopic Discectomy

   • Procedure: Thoracic approach using a camera through small chest ports to excise disc material.

   • Benefits: Direct visualization, minimal muscle cutting, shorter hospital stay.

3. Open Posterior Laminectomy & Discectomy

   • Procedure: Midline incision, removal of lamina and ligament to access and remove disc fragments.

   • Benefits: Excellent exposure for central herniations; efficient decompression.

4. Anterior (Transthoracic) Discectomy

   • Procedure: Thoracotomy to access anterior disc, remove pathology, and reconstruct segment.

   • Benefits: Direct removal of large central herniations; preserves posterior elements.

5. Posterior Instrumented Fusion

   • Procedure: Removal of compressive elements plus pedicle screw-rod fixation across involved levels.

   • Benefits: Stabilizes spine, prevents re-prolapse, treats instability.

6. Anterior Instrumented Fusion

   • Procedure: After disc removal, bone graft and hardware placed anteriorly to fuse T5–T6.

   • Benefits: Restores anterior column support, corrects alignment.

7. Minimally Invasive Thoracic Fusion

   • Procedure: Percutaneous pedicle screw placement with tubular retractors and graft.

   • Benefits: Less muscle injury, reduced blood loss, faster rehab.

8. Posterolateral Fusion with Bone Graft

   • Procedure: Harvest autograft or use allograft placed along transverse processes posteriorly.

   • Benefits: Augments stability with less hardware; traditional technique.

9. Percutaneous Disc Nucleoplasty

   • Procedure: Radiofrequency coblation of nucleus to decrease intradiscal pressure.

   • Benefits: Outpatient, small access, symptom relief without major tissue disruption.

10. Interspinous Process Spacer

• Procedure: Implant inserted between spinous processes to distract posterior elements.

• Benefits: Indirect decompression, preserves motion, minimal invasiveness.

(Surgical choice depends on herniation location, patient health, and surgeon expertise tandfonline.comen.wikipedia.org.)

Prevention Strategies

1. Maintain Core Strength & Flexibility

   • Regular core and back extension exercises to support spinal alignment.

2. Practice Safe Lifting Mechanics

   • Bend at hips/knees, keep load close to body, avoid trunk rotation under load.

3. Ergonomic Workstations

   • Proper desk height, lumbar support, frequent posture changes.

4. Healthy Body Weight

   • Reduces axial spinal load and disc stress.

5. Regular Low-Impact Aerobic Activity

   • Walking, swimming, or cycling to nourish discs via motion.

6. Avoid Prolonged Static Postures

   • Break up sitting or standing every 30 minutes with gentle movement.

7. Quit Smoking

   • Smoking impairs disc nutrition and healing.

8. Wear Supportive Footwear

   • Shock-absorbing shoes reduce transmission of ground reaction forces to the spine.

9. Back-Saving Tools & Techniques

   • Use tools with long handles, trolleys, or lifts to avoid bending under loads.

10. Educate on Pain-Science

• Understanding pain reduces fear-avoidance and fosters active prevention.

(Comprehensive prevention blends exercise, ergonomics, lifestyle, and education en.wikipedia.org.)

When to See a Doctor

• Red-Flag Signs: Sudden severe chest or back pain with weakness in legs, difficulty breathing, bowel/bladder dysfunction, or signs of spinal cord compression.

• Persistent Symptoms: Pain unresponsive to 4–6 weeks of conservative care.

• Neurological Changes: New numbness, tingling, or weakness in the abdomen, chest wall, or lower limbs.

• Systemic Signs: Unexplained fever, weight loss, or night sweats (possible infection or tumor).

Frequently Asked Questions

1. Can a thoracic disc backward slip heal on its own?
   Many backward slips improve with conservative care within 6–12 weeks by reducing inflammation and strengthening support structures.

2. Is surgery always required?
   No. Over 80% of thoracic disc issues respond to non-surgical treatment unless there is severe neurological compromise.

3. Will this condition cause paralysis?
   Rarely. Paralysis is uncommon unless there’s significant spinal cord compression. Prompt evaluation is crucial if weakness arises.

4. Can I return to sports?
   Yes, after gradual rehabilitation and clearance from your healthcare provider; focus first on core stability and posture.

5. Are corticosteroid injections helpful?
   They may offer temporary relief for radicular symptoms but have limited long-term benefit and carry risks.

6. How often should I do physiotherapy?
   Typically 2–3 sessions per week for 4–6 weeks, then taper based on progress.

7. Do I need an MRI?
   MRI is indicated if symptoms persist beyond 4–6 weeks or if neurological signs develop.

8. Will weight loss help?
   Yes. Reducing excess weight decreases spinal loading and may speed recovery.

9. Is a corset or brace recommended?
   Short-term bracing (1–2 weeks) can relieve pain, but long-term use may weaken muscles.

10. Can acupuncture cure it?
    Acupuncture can reduce pain perception but is not a cure; it’s an adjunct to comprehensive care.

11. Are supplements safe?
    Most are safe when used appropriately, but discuss with your doctor—especially if you have shellfish allergies (glucosamine).

12. Should I avoid all NSAIDs?
    Use the lowest effective dose for the shortest duration; alternative pain relievers may be considered if you have GI or cardiac risks.

13. Does smoking affect healing?
    Yes. Smoking impairs microcirculation and delays tissue repair. Quitting is strongly advised.

14. What’s the role of yoga?
    Gentle yoga can improve flexibility and stress management, but avoid deep twisting or extreme backbends until healed.

15. When can I expect full recovery?
    Most patients achieve significant pain reduction by 3 months; full functional recovery may take 6–12 months with continued rehab and prevention.
