Failed Back Surgery Syndrome (FBSS) is a chronic pain condition that occurs when back or spine surgery does not provide the intended relief—or when pain returns after a short period of improvement. Despite advances in surgical techniques, up to 20–40% of patients continue to experience persistent back pain, leg pain, or new neuropathic symptoms after surgery.At Samobathi Pain Clinic, we specialize in advanced, minimally invasive interventional treatments designed to relieve pain and restore function in patients struggling with Failed Back Surgery Syndrome (FBSS).


What Is Failed Back Surgery Syndrome (FBSS)?

Failed Back Surgery Syndrome (FBSS) refers to persistent or recurrent back pain, leg pain, or both, after one or more spine surgeries.Despite its name, FBSS does not mean that the surgeon made an error. Instead, it is often due to ongoing nerve irritation, scar tissue formation, adjacent segment disease, or incomplete pain generator identification.

FBSS is complex and requires a multidisciplinary, image-guided, interventional approach for successful long-term relief.


Causes of Failed Back Surgery Syndrome (FBSS)

Common causes include:


1. Scar Tissue Formation (Epidural Fibrosis)

Scar tissue may form around nerves after surgery, leading to persistent pain.

2. Recurrent Disc Herniation

A disc can re-herniate at the same level, compressing the nerve again.

3. Adjacent Segment Degeneration

Levels above or below the operated segment may degenerate over time.

4. Incomplete Decompression

Residual bone spurs, disc fragments, or stenosis may remain.

5. Wrong Pain Generator Identified Pre-Surgery

Pain may originate from facet joints, SI joint, or muscles instead of the disc.

6. Nerve Damage or Persistent Neuropathy

Long-term nerve compression may lead to chronic neuropathic pain.

7. Implant or Hardware-Related Issues

Screws, rods, or cages may irritate surrounding structures.


Symptoms of Failed Back Surgery Syndrome (FBSS)

Patients with Failed Back Surgery Syndrome (FBSS) typically experience:

  • Persistent low back pain

  • Radiating leg pain (similar to sciatica)

  • Burning, tingling, or numbness in the legs

  • Stiffness and limited mobility

  • Pain worsening with standing or walking

  • Muscle spasms

  • Emotional impact: frustration, anxiety, sleep problems

Symptoms may appear immediately after surgery or months to years later.


Diagnosis of Failed Back Surgery Syndrome (FBSS)

At Samobathi Pain Clinic, evaluation for Failed Back Surgery Syndrome (FBSS) includes:

  • Detailed review of surgical history

  • Physical and neurological examination

  • MRI with contrast (to differentiate scar tissue vs disc herniation)

  • CT scan for hardware evaluation

  • Electromyography (EMG)

  • Diagnostic nerve root blocks

  • SI joint and facet joint assessment

A precise diagnosis is essential to selecting the right interventional treatment.


Treatment Options for Failed Back Surgery Syndrome (FBSS) at Samobathi Pain Clinic

The treatment of Failed Back Surgery Syndrome (FBSS) focuses on reducing nerve irritation, improving mobility, and restoring quality of life—without additional unnecessary surgery.


Conservative Treatment for Failed Back Surgery Syndrome (FBSS)

Initial management may include:

  • Neuropathic pain medications

  • Muscle relaxants

  • Physiotherapy and core stabilization

  • Posture correction

  • Mental health support for chronic pain coping

However, FBSS often requires interventional pain management, especially for leg-dominant neuropathic pain.


Interventional Pain Management for Failed Back Surgery Syndrome (FBSS)


1. Epidural Steroid Injection (ESI)

Effective for reducing inflammation due to residual nerve compression or scar tissue.

2. Transforaminal Epidural Steroid Injection (TFESI)

Highly precise and effective for radicular leg pain in FBSS.

3. Caudal Epidural Injections

Ideal for patients with multiple operated levels or extensive scar tissue.

4. Adhesiolysis (Racz Procedure)

Breaks down epidural scar tissue using catheter-based techniques.Very effective in patients with epidural fibrosis.

5. Facet Joint Injections

Many FBSS patients also have facet-mediated back pain due to degeneration.

6. Radiofrequency Ablation (RFA)

Long-term relief for chronic facet joint–related pain.

7. SI Joint Injection

The sacroiliac joint often becomes dysfunctional after spine surgery.

8. Spinal Cord Stimulation (SCS)

One of the most effective treatments for Failed Back Surgery Syndrome (FBSS).Benefits:

  • Reduces leg and back pain significantly

  • Decreases medication dependence

  • Improves mobility and sleep

  • Proven long-term results

SCS is the gold standard for severe neuropathic pain in FBSS.

9. Intrathecal Drug Delivery System (IDDS)

Used in rare, severe cases where other treatments fail.


Preventing Failed Back Surgery Syndrome (FBSS)

Long-term prevention strategies include:

  • Maintaining good posture

  • Avoiding heavy lifting

  • Regular physiotherapy

  • Core strengthening

  • Proper ergonomics

  • Early treatment of recurring symptoms

A proactive approach reduces risk of repeat surgeries and chronic pain.
