Disc denervation is a procedure designed to treat certain types of chronic back pain, more specifically, conditions caused by defects in the intervertebral disc located between pairs of vertebrae (spinal bones). Chronic pain associated with disc anomalies is also termed discogenic pain. Disc denervation is the disruption of spinal nerves that transmit discogenic pain signals with electrothermal probes. This renders these nerves unable to conduct signals and, therefore, brings relief from chronic pain.
