Radiofrequency Ablation for Spine Pain

Radiofrequency ablation, also called rhizotomy or medial branch ablation, is a minimally invasive procedure for pain arising from selected facet joints in the spine. A clinician guides a needle near a small sensory nerve and uses a radiofrequency generator to create controlled heat. This interrupts the nerve's pain signalling without removing the joint or treating every possible source of back pain.

Radiofrequency ablation uses controlled heat to interrupt pain signals from selected spinal nerves, which may reduce pain and support movement for an extended period.

Before treatment, diagnostic injections may help show whether the suspected nerve is contributing to your symptoms. The procedure is usually performed with image guidance and local anaesthetic; sedation may be discussed if needed.

Some people notice temporary numbness from the local anaesthetic first, followed by soreness when it wears off. The treated nerve may take time to settle, so improvement can build gradually rather than appearing immediately. Your clinician will explain what level of activity is sensible while the area recovers.

Short-term effects can include tenderness, bruising, a warm or tingling feeling, or a temporary increase in the familiar pain. Less commonly, altered sensation or weakness can occur near the treated area. Contact the treating service promptly for worsening weakness, spreading numbness, fever, severe headache, or a new problem with bladder or bowel control.

Radiofrequency ablation is a procedure, not a daily medicine or a fixed course of therapy. Pain relief can last for an extended period, but the nerve may recover and symptoms can return. A review can help decide whether rehabilitation, another procedure, or a different pain plan is appropriate.

The aim is to reduce pain signals so that walking, sleep, exercise, and physiotherapy become more manageable. It does not rebuild a worn disc or reverse spinal arthritis. Results depend on whether the treated nerve is the true pain generator and on the wider condition of the spine.

A spine or pain specialist may consider it for persistent, function-limiting pain linked to facet joints, especially when other measures have not provided enough relief and diagnostic blocks support the target. It may be discussed alongside care for Degenerative Disc Disease, Facet Joint Syndrome, or Lumbar Spondylosis. Lower Back Pain can have several sources, so assessment should include symptoms, examination, and relevant imaging.

You lie in a position that allows access to the treatment area. The skin is cleaned and numbed. Using imaging, the clinician places a fine needle beside the selected nerve, checks its position with small test signals, and then applies radiofrequency energy for a controlled interval. The needle is removed and the area is covered. You are observed briefly before going home, with transport arrangements based on the sedation plan.

Keep the area clean and follow the discharge instructions. Gentle movement is commonly encouraged, while strenuous lifting or sport may need to wait until soreness has settled. Arrange a follow-up to assess pain, function, and the role of exercise. A pain diary can distinguish early procedural soreness from later change in your usual symptoms.

Possible risks include infection, bleeding, temporary nerve irritation, altered sensation, and an inadequate response. Tell the clinician about medicines, allergies, pregnancy possibility, infection, and any blood-clotting condition before treatment. Seek urgent medical help for new severe weakness, loss of bladder or bowel control, or rapidly worsening numbness.

Depending on the suspected pain source, options may include structured physiotherapy, activity modification, medicines, or a Facet Joint Injection. Your plan may focus on strength, mobility, sleep, and pacing even when a procedure is chosen. A specialist can explain why one approach fits your examination and goals.

Look for a licensed pain medicine, spine, orthopaedic, or rehabilitation clinician who can explain the suspected pain generator, imaging guidance, diagnostic testing, aftercare, and alternatives. Bring your symptom history and a list of medicines. Ask who will review you if pain or neurological symptoms change after the procedure.
