Radiofrequency Lesioning

Frequently asked questions

Fluoroscopically guided radiofrequency thermocoagulation was introduced in 1974 for facet joint denervation for facet joint disease and pain. It has since been used to perform neurolysis and lesioning of the trigeminal ganglion, dorsal root entry zone, and cordotomies. It has been used in the treatment of peripheral nerve lesions and neuromas, and coccydynia. Currently the major use of RFL is in the treatment of facet disease.

Radiofrequency lesioning requires the placement of probes percutaneously with the use of fluoroscopy , sensory and motor stimulation to assure proper placement. Once the proper stimulation occurs and the probe is placed near the nerve the probe is heated to 90 degrees C for 60 to 90 seconds.

Radiofrequency lesioning is performed only after pain relief is obtained after a diagnostic block. RFL is performed if prolonged relief is not obtained with these blocks. A RFL lesion will not provide a permanent cure as the nerve fiber will regenerate usually within 12 months. The time of relief provided by RFL has a wide variance and may have to be repeated in order to provide optimal relief of pain complaints.
