What is Radiofrequency Ablation?
A radiofrequency ablation (RFA) is an interventional procedure performed by a highly trained radiologist under imaging guidance. The procedure involves using heat to destroy nerve tissue, and minimise pain.
RFA is suitable for patients who have previously had short-lived or little response to steroid injections. This procedure can provide long-term pain relief ranging from 6-18 months.
A radiofrequency ablation aims to improve neck, back and joint pain so you can reduce the amount of pain medication you are taking, and improve your daily quality of life.
There is no specific preparation for an RFA. However, two appointments may be needed. The first appointment is a trial block to see if the RFA will be effective. The RFA will occur at the second appointment.
If you have a pacemaker, please let staff know before the procedure, as the RFA has the potential to cause the pacemaker to malfunction.
Please wear loose clothing to your appointment, preferably a shirt and pants/skirt, so we may access the treatment site easily. In some instances, you may be given a gown to wear. You may also be asked to remove objects like watches or jewellery for your scan, so consider leaving any valuables at home.
Please arrive 15 minutes before your appointment with your Medicare card and/or concession card, your referral, and any relevant previous scans. If you have a child aged 6 or under, they must be supervised by an adult other than the patient.
After you arrive, the procedure will be discussed with you by one of the team members, and you will have the chance to ask any questions of the radiologist or any of the team members before proceeding.
A team member will then prepare you for the procedure, and a local anaesthetic will be administered.
Under image guidance, a needle is carefully placed in the area of affected nerves. The needles are connected by insulated wires to grounding pads, which are attached to your back or thigh, and a generator. The current from the generator heats the tips of these needles, which then stops the nerves from sending pain signals to the brain.
There are two different types of radiofrequency ablation – continuous and pulsed. Continuous radiofrequency uses high voltage current to generate heat up to 80°C for 90-110 seconds to break down nerves, while pulsed radiofrequency ablations are conducted at a lower temperature of 42°C and help modulate the nerve function whilst preserving motor function.
Your appointment should take around 20 minutes. It usually takes 10 minutes for set-up to be complete, and a further 10 minutes for the procedure itself.

Qscan offers continuous and pulsed radiofrequency ablations as an in-patient service, so you will be able to return home on the same day as the procedure.
You will require a driver to take you home and you should not drive for 24 hours following the injection. We ask that you avoid any strenuous physical activity, including standing for more than one hour at a time, for 48 hours post procedure.
If you experience pain following the procedure, treat with a cold pack, paracetamol and anti-inflammatory medication (if applicable).
If you develop fever with joint pain, swelling, redness and warmth in the week following an injection, call Qscan on 1300 177 226 or contact your GP. If you are still concerned and it is after hours, please contact your nearest Emergency Department.
