Radiofrequency Lesioning (RF)
Radiofrequency Lesioning Procedure
If you have at least temporary improvement from diagnostic spinal injections, radiofrequency lesioning may be an effective way to interrupt the pain signals for an extended period of time. These procedures are done much the same way as other spinal injections. Once positioned appropriately, a fluoroscope (X-ray guidance machine) assists in identifying the specific area to be treated. The area is cleaned and the skin is numbed. The special radiofrequency needle is inserted under X-ray guidance next to the pain fibers in your spine. The microelectrode is then inserted through the needle to begin the stimulation process. During this process you will be asked by your doctor if you are able to feel a tingling sensation.
The object of the stimulation process is to help determine if the electrode is in the optimum area for treatment, thus producing the best relief. Once the needle and electrode placement is verified, treatment can begin. The small radiofrequency current will travel through the electrode and into the surrounding tissue, causing the tissue to heat and eliminate the pain pathways. You should alert the doctor if at any time during the procedure you experience any significant discomfort. Depending on the procedure performed, the typical procedure time is 30 to 60 minutes.
Radiofrequency Lesioning Recovery
You may experience some soft tissue discomfort at the needle placement sites following the procedure. As with any soft tissue wound, this usually subsides over the next several days. Occasionally, you may experience a burning or numb sensation, which usually subsides over several weeks. The procedure is usually done on an outpatient basis.
Radiofrequency treatments to the tissues block pain signals for a prolonged period of time; however, the human body may regenerate the pain pathways over time. It is not unusual that the procedure may need to be repeated, but most patients report longer lasting relief than with other spinal injections, which are commonly done with local steroids.
Radiofrequency treatment will allow improvement in your day-to-day activities. You should be able to resume normal activities, including work, as soon as you feel able. However, any pre-existing physical restrictions you have prior to the procedure may still remain.
