Overview
Understanding radiofrequency ablation
For pain care, a needle-like probe is positioned near a specific sensory nerve using imaging. Radiofrequency energy heats a small area of tissue around the target so the nerve carries fewer pain signals.
The procedure is not suitable for every source of back, neck, joint, or nerve pain. A focused examination and, in many pathways, a successful diagnostic block help determine whether the target is appropriate.
Useful context
When this may be discussed
- Selected facet-joint pain in the neck or lower back
- Selected sacroiliac or knee pain pathways
- Other localized pain carried by an identifiable sensory nerve
At the clinic
What the process may involve
- 01
Review of the suspected pain source and response to any diagnostic block
- 02
Positioning, monitoring, skin preparation, and local anesthetic
- 03
Image-guided placement and controlled radiofrequency treatment
- 04
Temporary soreness and a follow-up plan to assess function and pain
Benefits, limits, and risks
Questions to discuss before treatment
- Pain relief is not guaranteed and nerves can recover over time.
- Risks can include bleeding, infection, localized numbness, temporary pain increase, and injury to nearby tissue or nerves.
- Ablation reduces a selected pain signal; it does not remove arthritis or repair the underlying structure.
