A number of studies have been performed on the efficacy of RF treatment.
Epidural Pulsed RF (PRF) at the dorsal nerve roots and dorsal root ganglia (DRG) can be used to treat radicular neuropathy.1,2,3 Epidural placement enables treatment of multiple spinal levels via a single needle, and targetry of nerves inaccessible due to normal anatomy, foraminal stenosis, or hardware.1,2,3 Temperature control at 42°C limits thermal effects and ensures safety.1,2,3,4
The average duration of pain relief is between four and 26 months, depending upon which nerve is being treated. However, pain relief may range from anywhere between four weeks to 18 months. In some cases, there is no benefit.
