What are the treatment options for sciatica?

Sciatica Treatment Options

The treatment of sciatica should begin with conservative management for 6-8 weeks, including activity modification, NSAIDs, and physical therapy, before considering interventional or surgical approaches. 1

Initial Assessment and Diagnosis

• Sciatica is a symptom rather than a specific diagnosis, characterized by lower limb pain radiating below the knee into the foot and toes 2, 3
• Most cases (90%) resolve within 6 weeks regardless of treatment 1
• Diagnostic approach:
  • Rule out red flags requiring urgent evaluation:
    • Fever and chills (suspect vertebral osteomyelitis) 1
    • Progressive neurological deficits 1
    • Cauda equina syndrome 1
  • MRI is recommended if symptoms persist beyond 6-8 weeks or if red flags are present 1, 3

Conservative Management (First 6-8 Weeks)

Pharmacologic Options

1. First-line therapy:

   • NSAIDs as initial treatment 1
   • Topical NSAIDs with or without menthol gel 1
   • Acetaminophen for patients who cannot take NSAIDs 1

2. Second-line options (if inadequate relief after 2-4 weeks):

   • Muscle relaxants (e.g., cyclobenzaprine 5-10mg at bedtime) 1
   • Neuropathic pain medications for prominent radicular component:
     • Gabapentin or pregabalin 1, 4, 5
     • Tricyclic antidepressants (nortriptyline or desipramine 10-25mg at bedtime) 1

3. Avoid:

   • Overuse of opioids as first-line therapy 1
   • Prolonged bed rest 1, 2

Non-Pharmacologic Approaches

• Remain active with appropriate modifications 1, 2
• Core strengthening exercises 1
• Manual therapy techniques 1
• Patient education about expected course (favorable in most cases) 1, 3
• Proper body mechanics guidance for daily activities 1

Risk Stratification and Follow-up

• Reassess in 2-4 weeks to evaluate treatment response 1
• Use STarT Back tool at 2 weeks for risk stratification 1:
  • Low risk: Encourage self-management
  • Medium risk: Refer to physiotherapy with patient-centered plan
  • High risk: Refer for comprehensive biopsychosocial assessment

Advanced Interventions (After 6-8 Weeks of Failed Conservative Treatment)

Interventional Options

• Consider epidural corticosteroid injections or transforaminal peri-radicular injections 2
• Radiofrequency facet denervation (RFA) may be considered if:
  • Patient has failed 6+ weeks of conservative treatment
  • MRI rules out disc herniation or significant vertebral canal narrowing
  • Two separate diagnostic medial branch blocks confirm facet joint pain 1

Surgical Considerations

• Indications for surgical intervention:
  • Cauda equina syndrome (emergency)
  • Progressive neurological deficits
  • Intractable pain despite conservative management
  • Persistent symptoms after 6-12 weeks of conservative treatment 1
• Surgical options:
  • Discectomy (effective in short term but not superior to prolonged conservative care in long term) 1, 2
  • Decompression for central spinal stenosis without significant spondylolisthesis 1
  • Fusion for spinal stenosis with instability, spondylolisthesis, or deformity 1

Special Populations

• Elderly patients:

  • Slower progression of exercise intensity
  • Careful medication management due to higher risk of side effects 1

• Patients with cardiovascular disease or renal impairment:

  • Special attention with NSAID use 1
  • Consider acetaminophen as alternative 1
  • May benefit from multidisciplinary approach 1

Common Pitfalls to Avoid

• Ordering routine imaging for nonspecific back pain (can lead to unnecessary interventions) 1
• Delaying appropriate imaging when red flags are present 1
• Prolonged bed rest (outdated recommendation from older studies) 1, 6
• Failing to differentiate radicular pain from referred pain 2
• Premature surgical referral before adequate trial of conservative management 1
• Delayed surgical referral when appropriate indications exist 1
