Radiofrequency denervation
Radiofrequency denervation is a minimally invasive procedure used to reduce pain arising from the facet joints by targeting the small nerves that carry pain signals.
It is typically considered when facet joint injections have provided temporary relief, helping confirm the source of pain.

Understanding radiofrequency denervation
Reducing pain by targeting nerve signals
Radiofrequency denervation is a procedure designed to reduce pain by interrupting the nerve signals coming from the facet joints.
Small nerves known as medial branch nerves carry pain signals from these joints. By applying controlled heat to these nerves, the procedure reduces their ability to transmit pain.
At Total Spine Health, radiofrequency denervation is only recommended when there is clear evidence that facet joints are the source of pain, usually confirmed through previous injections. The aim is to provide longer-lasting relief as part of a structured treatment pathway.
What is radiofrequency denervation?
Interrupting pain signals from the facet joints
Radiofrequency denervation uses a specialised needle to deliver controlled heat to the nerves supplying the facet joints.
This process temporarily disrupts the nerve’s ability to send pain signals to the brain, helping reduce symptoms.
The procedure is performed using imaging guidance to ensure accurate placement, and is typically carried out as a day-case treatment.
When this treatment may be used
Pain patterns linked to facet joint irritation
Radiofrequency denervation is most effective for pain that has been identified as facet joint-related.
- persistent lower back or neck pain
- pain worsened by movement or extension
- localised pain rather than widespread symptoms
- stiffness, especially after rest
- pain returning after initial injection relief
- limited improvement with other treatments
These symptoms are often confirmed through diagnostic injections before proceeding.
CONDITIONS TREATED
When radiofrequency denervation may be appropriate
Radiofrequency denervation is used in carefully selected cases where facet joints are confirmed as the source of pain.
When radiofrequency denervation may be considered
When longer-lasting relief is needed
Radiofrequency denervation is usually considered after facet joint injections have confirmed the source of pain and provided temporary relief.
It is not typically used as a first-line treatment.
- confirmed facet joint pain
- good but temporary relief from injections
- persistent or recurrent symptoms
- pain affecting daily activities
- non-surgical treatments not sufficient
- desire to avoid or delay surgery where possible
ASSESSMENT AND SURGICAL PLANNING
Confirming suitability for treatment
Careful assessment ensures that radiofrequency denervation is appropriate and likely to be effective.
- review of previous injection response
- detailed symptom assessment
- imaging correlation where needed
- confirmation of facet joint involvement
- discussion of expected outcomes
- planning of targeted treatment levels
This step is essential to maximise the chances of success.
PROCEDURES AND TECHNIQUES
How radiofrequency denervation is performed
The procedure is carried out using imaging guidance to accurately target the nerves supplying the facet joints.
Controlled heat is applied to the nerves transmitting pain signals.
X-ray imaging ensures precise positioning of the treatment needle.
Specific nerves are treated based on the location of symptoms.
Treatment may involve one or more spinal levels depending on the pain pattern.
Usually performed without the need for an overnight hospital stay.
Recovery after radiofrequency denervation
What to expect after treatment
Most patients return home the same day and can resume light activity shortly afterwards.
Pain relief may not be immediate, as the treated nerves take time to fully stop transmitting pain signals.
- same-day discharge
- gradual return to normal activity
- temporary soreness at treatment site
- pain relief developing over days to weeks
- follow-up to assess response
- ongoing rehabilitation where appropriate
Relief can last several months, although nerves may slowly recover over time.
FAQs
Frequently asked questions about radiofrequency denervation
How long does pain relief last?
Relief can last several months, although this varies between patients.
Is the procedure painful?
It is usually well tolerated, with local anaesthetic used to minimise discomfort.
How quickly will I notice improvement?
Relief may develop gradually over a few weeks.
Can the procedure be repeated?
Yes, if symptoms return and the initial treatment was effective.
Is it a permanent solution?
No. Nerves can regenerate over time, so symptoms may return.
