Procedure using radiofrequency energy to alter targeted tissue, including selected nerve fibres involved in pain.

Understanding the approach

Radiofrequency ablation delivers energy through a probe to alter pain transmission in a targeted nerve. In spinal practice it often concerns medial branches supplying facet joints. It does not remove the sciatic nerve and does not decompress a herniated disc.

Indications and assessment

Selection rests on pain compatible with the target, insufficient benefit from conservative measures and, frequently, the response to a diagnostic block. Osteoarthritis on imaging alone is not enough. The specialist must assess whether another explanation better accounts for the symptoms.

Benefits, limitations and precautions

Some people achieve relief lasting months, but responses vary and symptoms can return. The procedure does not repair joint cartilage. Local pain, nerve irritation, numbness and burns are possible; infection and nerve injury are less frequent complications that should also be discussed before deciding.

Place in the care pathway

This specialist medical procedure is not a noninvasive TAGMED service. Exercise and functional strategies may remain helpful before or afterward, following the treating team’s instructions. Repeating a procedure should depend on the previous benefit and the current clinical situation.

Goals should be practical: walking farther, returning to a chosen activity or reducing symptoms that interfere with sleep. Improvement immediately after an intervention does not establish lasting benefit. Follow-up compares function with the starting point, records adverse effects and considers progress between appointments. An inadequate response should prompt a review of the clinical explanation or proposed approach, rather than an automatic extension of the same treatment.

Before starting, describe the outcome you want, treatments already tried and difficulties encountered. Ask how the response will be measured and when another option would be preferable. Available reports complement the discussion without replacing your current experience, priorities or preferences.

Frequently asked questions

Is it herniated disc surgery?

No. It targets a defined pain pathway rather than a disc fragment.

Does a positive block guarantee success?

No. It assists selection without eliminating uncertainty.

Does the effect last for life?

No. Symptoms may recur.

Are all radiofrequency procedures alike?

No. The target, temperature and technique vary with the indication.

What if there is no benefit?

Review the diagnosis and other options rather than automatically repeating the procedure.
