Lumbar Radiofrequency Ablation
RFA, or Radiofrequency Ablation, uses energy to disrupt nerve function. When it is done to a lumbar medial branch nerve, the nerve is no longer able to transmit signals from a painful facet joint. If you have any questions after reading this information about lumbar radiofrequency ablation please call us. We, at Spine Physicians Institute, have performed this procedure on countless patients over the years.
- During the procedure, an IV may be inserted to administer intravenous medications to help you relax.
- Local anesthetic will also be used to numb your skin.
- Fluoroscopy, a type of x-ray machine, is used to ensure proper placement of the needle.
- Stimulation of the nerve is used to verify correct placement, which may provoke pain and cause muscle twitching.
- Once correct placement of the needle is verified, the area will be numbed.
- Finally, radiofrequency energy is then used to disrupt the medial branch nerve.
You are monitored for up to 30 minutes after the injection. You may feel sore for 1-4 days following the injection. Your back may also feel numb, weak or itchy for a couple of weeks. Full pain relief normally takes 2-3 weeks.
Nerves can take up to 18 months to regenerate after an RFA. Your pain may or may not return after the nerves regenerate. If your pain returns, the lumbar radiofrequency ablation can be repeated. If you are still experiencing pain it is best to give us a call.
