A series of 26 patients with chronic pain were treated with percutaneous radiofrequency lesioning of the dorsal root ganglion. Ten patients had an excellent result, which persisted in 8 to the present time or death, and 5 had a good persistent result. A useful persisting result was therefore obtained in 13 patients with a further 2 patients having temporary benefit.
