Does radiofrequency ablation treat lumbar spondylosis?

Lumbar spondylosis describes age-related or mechanical changes in the lower spine, including facet-joint wear. Radiofrequency ablation uses heat created by radio waves to interrupt selected nerves carrying pain signals from an irritated joint. The procedure targets pain communication rather than the discs, bones, or arthritis itself. It is generally considered after an assessment identifies a likely facet-joint source and simpler measures have not provided enough relief.

A spine or pain clinician can review your pain pattern, examination findings, imaging, medicines, and activity limits. A diagnostic nerve block may be used before ablation to check whether the suspected nerves are contributing to your pain. If treatment is chosen, discuss preparation, temporary soreness, follow-up, and how exercise-based rehabilitation will fit around it. Physiotherapy can still matter because stronger trunk and hip muscles, pacing, and movement practice address function while the pain is being managed.

Seek urgent medical assessment for new loss of bladder or bowel control, numbness around the groin, rapidly worsening leg weakness, or severe back pain after a significant injury. Contact your treating team if pain, redness, drainage, fever, or weakness develops after a procedure. These findings need assessment rather than an assumption that the spondylosis or treatment is responsible.

Ask: Which structure is most likely generating my pain? Would a diagnostic block help confirm that source? What improvement should I use to judge the treatment? How will my medicines and rehabilitation be managed before and after the procedure?
