LUMBAR RADIO-FREQUENCY ABLATION
For Low Back, Hip, Groin and Leg Pain
What is a lumbar Radio-frequency ablation?
A lumbar Radio-frequency ablation (LRFA) also known as a facet joint Rhizotomy is a minimally invasive procedure that destroys the medial branch nerves which stops the pain signals for 6 to 12 months following the procedure. These peripheral nerves do not have motor function so mobility is retained and pain can be significantly reduced.
What conditions can a lumbar RFA treat?
Lumbar RFA may be an effective treatment for any condition that causes facet joint inflammation or irritation. These conditions include osteoarthritis of the spine, facet arthropathy, spinal injuries, neuropathic spine conditions.
How does a lumbar RFA work?
During the procedure the medial branch nerves are cauterized and this prevents the pain signals from the facet joints to reach the brain. The treatment may reduce pain in the low back, hips, groin and legs. Peripheral nerves will regrow in 6 to 12 months and your pain may return as the nerves return to function.
How is the lumbar RFA performed?
The patient lays face down and the lumbar spine is visualized using fluoroscopy (continuous x-ray). While using sterile techniques numbing medicine is injected in the skin and tissue near the vertebrae. A needle is then placed, using bony landmarks, close to the medial branch nerves and a radiofrequency is sent through the nerve creating heat which cauterizes the nerves. It is common to experience discomfort and burning sensation during the procedure.
What to expect after lumbar RFA?
Following the procedure you may experience pain, burning or numbness for up to 3 weeks. Some patients will experience near immediate relief while most will have relief within 1-2 weeks of the procedure. It can take up to one month before receiving full relief from the procedure. It is best to rest for 24 hours following the procedure and use ice for pain relief. Ice therapy should be 20 minutes then 20 minutes off with the skin covered to avoid ice burn. You can return to normal activity level after 1-2 days. The procedure can last months to years and can be repeated after 6 months to maintain good pain control.
