How effective is radiofrequency ablation for lumbar spondylosis?

Lumbar spondylosis describes age-related wear in the lower spine, including changes around discs and facet joints. A scan can show these changes without proving that they cause the pain. Radiofrequency ablation targets selected small nerves carrying pain from a suspected source, often facet joints, using controlled heat. It cannot remove a bone spur, widen a narrowed canal, or restore worn cartilage.

The most useful candidates are identified through a matching pain pattern, examination, and sometimes diagnostic nerve or joint injections. Relief may be partial, and local soreness or altered sensation can follow treatment. Once symptoms settle, a graded programme can improve trunk and hip strength, movement, and tolerance for walking or sitting.

Ask the clinician to connect your symptoms with the proposed target and explain what the diagnostic findings mean. Review medicines, preparation, post-procedure transport, and temporary lifting or driving restrictions. Set a functional goal, such as standing longer or returning to a chosen activity, and agree how it will be measured. Continue the recommended movement plan and report changes rather than increasing loads abruptly.

Seek urgent care for new difficulty passing urine or stool, numbness around the inner thighs or groin, or worsening weakness in either leg. Contact the procedure team for fever, drainage, spreading redness, severe headache, or pain that becomes increasingly intense. Back pain after a significant fall or collision, especially with new weakness or loss of sensation, needs prompt assessment.

Which part of my lumbar spine is thought to cause pain? Does my examination suggest nerve compression that needs another approach? What did any diagnostic block tell us? What daily activity should improve, and how will I rebuild it safely? Which warning signs should prompt immediate help?
