Radiofrequency Ablation in Delhi | Long-Lasting Pain Relief at Eshna Pain & Palliative Centre

Radiofrequency Ablation (RFA) is one of the most effective and durable interventional pain procedures available. It uses controlled heat energy to interrupt pain-carrying nerve fibers — providing relief that can last 9–18 months or longer. At Eshna Pain & Palliative Centre, RFA is performed under imaging guidance by fellowship-trained pain specialists.

How Does Radiofrequency Ablation Work?

A thin needle electrode is placed under imaging guidance adjacent to the targeted nerve. Radiofrequency energy is delivered through the electrode tip, generating a localized heat lesion (70–80°C) that interrupts the nerve's ability to transmit pain signals to the brain. The procedure does not damage surrounding structures, blood vessels, or motor nerves when performed correctly.

Types of RFA

• Conventional (Thermal) RFA: Creates a heat lesion. Used for facet joint pain, sacroiliac joint pain, knee genicular nerves, and cancer pain

• Pulsed Radiofrequency (PRF): Uses intermittent pulses producing neuromodulation rather than tissue destruction. Used for nerve root pain (sciatica, cervical radiculopathy), and dorsal root ganglion

Conditions Treated with RFA at Eshna

• Lumbar Facet Joint Pain (Medial Branch RFA): Most established indication. Provides 9–18 months of relief

• Cervical Facet Joint Pain: For chronic neck pain after whiplash or cervical spondylosis

• Sacroiliac Joint Pain: Lateral branch RFA for SI joint dysfunction

• Genicular Nerve RFA for Knee Pain: Effective for moderate-to-severe knee osteoarthritis

• Cancer Pain (Neurolytic RFA): For refractory cancer pain syndromes

Trigeminal Radiofrequency Thermocoagulation: For trigeminal neuralgia (selected patients)

Conditions Treated with RFA at Eshna

Q: How long does RFA last for back pain?

A: Lumbar medial branch RFA typically provides relief for 9–18 months. As nerves regenerate, the procedure can be repeated with equivalent or better outcomes.

Q: Is RFA permanent?

A: No — the targeted nerves regenerate over time, typically over 12–18 months. RFA can be safely repeated. Some patients have maintained relief through multiple treatment cycles for years.

Q: Am I a candidate for RFA?

A: The best candidates are those who have had a positive response (>50% pain relief) to a diagnostic nerve block targeting the same nerve. Our doctors evaluate your imaging, clinical history, and diagnostic block results before recommending RFA.
