Contact us about facet denervation
It's easy to find out more about treatment by giving us a call or completing our enquiry form.
Radiofrequency denervation, also known as facet denervation, is a specialised form of treatment to cause heat damage to the two nerves that supply the facet joints, small pairs of joints which link your vertebrae together.
These nerves transmit pain sensations from the joints but have very little other function. By damaging them, the nerves stop sending pain signals to your brain.
Radiofrequency denervation is also known as facet rhizolysis, radiofrequency ablation or radiofrequency neurotomy.
Your GP or Consultant may suggest facet denervation if your back pain starts in your facet joints. They’ll only suggest the radiofrequency denervation procedure if other treatments, such as physiotherapy, haven’t helped.
Your Consultant will help you into position, so that you’re lying on your front. They’ll inject a local anaesthetic which will numb the area. Once the area is numb, your Consultant will pass a fine hollow needle towards the nerves, with the help of a Computerised Tomography (CT) scan.
When the needle is in the right place, they’ll pass a probe (thin wire) through the needle. The position of this probe is very important, so they’ll check using two tests:
When the probe is correctly positioned, your Consultant will give you an intravenous sedative to relieve any discomfort during the procedure. The tip of the probe is heated to 80 degree centigrade, which is enough to cause a heat lesion to the nerve.
As with all procedures, facet denervation carries some risks and side effects. We take every precaution to reduce the risks as far as possible but, in some cases, the following may occur:
Please let the Diagnostic Imaging department know if you’re diabetic, have a cough or cold or any kind of infection.
Female patients who are, or might be, pregnant must inform the department in advance.
It’s essential that we know in advance if you’re taking any blood thinning medication as this may need to be stopped prior to the procedure. Failure to inform the department prior to your procedure date could result in your treatment being cancelled on the day.
Please call 01580 857 492 and ask to speak to the Imaging secretaries.
You’ll be given a date to attend the ward for pre-assessment. Once you’ve passed your pre-assessment, one of our nursing staff will escort you to our Diagnostic Imaging department for your procedure.
Here you’ll be introduced to the team looking after you in Diagnostic Imaging. This will include the Consultant Radiologist, Radiographers and Radiology Assistant.
It’s very likely that you will have already tried other treatments, such as painkillers and physiotherapy before being referred for radiofrequency denervation treatment but your Consultant can discuss alternatives with you.
If you’ve already responded well to diagnostic injections, the facet denervation procedure has a good chance of long-term relief from back pain.
It might take up to three weeks for you to feel any benefit, but about half of cases can expect relief from symptoms for between three months and one year.
It’s important to know that the nerve can regrow so your pain may come back. However, if you responded well to the first injection, you’re likely to benefit from a repeat injection.
Prior to your procedure a nurse will take some details from you and check you are fit for your procedure. You’ll be asked to sign a consent form and will have an opportunity to ask the Consultant Radiologist any questions.
You should expect to remain on the recovery ward for 2-4 hours after. The nurse looking after you will ensure you are fit enough to go home prior to discharging you.
You must NOT drive home or travel home by public transport. Please arrange for someone to collect you from the hospital. You may however travel home by taxi.
Once you’re at home, it’s important that you rest for a couple of hours before you start to resume your normal activities. Don’t do any excessive exercise or heavy work for the first few days.
Continue to take your pain tablets until you notice any improvements in your symptoms. You can remove the dressing over the treatment site the following morning after the procedure.
If you have any concerns, please contact the Imaging Department on 01580 857 492 and speak with one of our Radiographers. If you need to contact someone out of hours, call NHS 111 and tell them you’ve had this procedure.
