Percutaneous radiofrequency denervation of spinal facets. Treatment for chronic back pain and sciatica

J Neurosurg. 1975 Oct;43(4):448-51. doi: 10.3171/jns.1975.43.4.0448.


A technique for radiofrequency localization and coagulation of articular nerves supplying the spinal facets is described and results are reported from a series of 207 patients followed 6 to 21 months (mean 31 months). Relief of pain was achieved in 79% of previously unoperated patients, in 41% of those with laminectomy but no fusion, and in 27% of those with an earlier fusion. No neurological complications were encountered.
