Radiofrequency Lesioning
Radiofrequency Lesioning ProcedureThe RFL procedure is performed under local anesthetic. It is important that the patient is awake and aware, since part of the procedure requires patient feedback. A thin needle is inserted into the back and viewed under live x-ray (fluoroscopy). Once the needle is in the correct position close to the nerve, electrical current is supplied, stopping the nerve from signaling. The procedure is a good less invasive approach to traditional back surgery and can be completed in less than 1 hour.The effect is called “semi-permanent” and lasts about 6 to 12 months. I think anything that lasts 6 months is better named “temporary”… Expectations for Radiofrequency LesioningThe RFL procedure is dependent upon 2 important criteria to be effective. First, is accurate diagnosis. If the treated nerve is not the correct source of pain, then the procedure will be a waste. Second, the treated nerve cannot actually be seen under x-ray. The surgeon can only approximate the location of the nerve, by using bone as a guide. This is usually accurate, but individual anatomy may place the nerve further away from the electrical pulse, creating a decreased effect.If everything works out right, the pain will be relieved or significantly reduced. Unfortunately, this is a surgical treatment and not a CURE. The benefits are temporary and the procedure must be repeated many times to enact long term back pain relief. If you are working towards a CURE and simply need symptomatic treatment in the short term, then I believe that this might be an excellent procedure to investigate. The risk is low and the results can be excellent. Just remember, it is basically a “surgical aspirin” and the effect will simply not last…
