Percutaneous Intradiscal Radiofrequency as A Treatment for Radicular Pain From Lumbar Disc Herniation

Percutaneous Intradiscal Radiofrequency as A Treatment for Radicular Pain From Lumbar Disc Herniation

The goal of this clinical trial is to demonstrate the efficacy of percutaneous intradiscal radiofrequency as a treatment for radicular pain from lumbar disc herniation.

The main question it aims to answer is:

• Can percutaneous intradiscal radiofrequency lower the severity of radicular pain from lumbar disc herniation Participants will be treated with percutaneous intradiscal radiofrequency and evaluated for radicular pain severity before and 3 months after the procedure.

There is no comparison group.

Inclusion Criteria:

1. 18-85 year-old patients with radicular pain from lumbar disc herniation for ≥ 3 months
2. Lumbar disc herniation ≤ 2 locations evidenced by MRI, with ≥ 50% remaining disc height, without disc sequestration
3. Previously treated with epidural steroid injection (ESI) and achieved ≥ 50 % pain relief from local anesthetic effect, confirming radicular pain from lumbar disc herniation, but did not respond to ESI (< 50 % Pain relief or pain relief < 3 months)

Exclusion Criteria:

• Patient refusal
• Discitis
• Previous lumbar spine surgery
• Progressive neurological deficit and/or cauda equina syndrome
• Coagulopathy
• Allergic to any medication in study protocols
• Unable to rate the pain
• Pain in any area worse than the radicular pain
