Electrodenervation

Electrodenervation is a medical procedure that involves the targeted destruction of nerve tissue using electrical currents. This technique is primarily employed in the management of chronic pain conditions, particularly those originating from the facet joints of the spine. The principle behind electrodenervation, also known as radiofrequency ablation or rhizotomy, is to interrupt the transmission of pain signals from the affected nerves to the brain.

The procedure typically begins with precise imaging, often fluoroscopy or CT scans, to accurately locate the specific nerves responsible for transmitting pain. Once the target nerves are identified, a specialized needle electrode is inserted under local anesthesia. Electrical current is then passed through the electrode, generating heat that selectively ablates or disables the nerve fibers. The intensity and duration of the electrical stimulation are carefully controlled to achieve the desired therapeutic effect without damaging surrounding tissues.

Patients undergoing electrodenervation are usually selected after conservative treatments such as physical therapy and injections have failed to provide adequate relief. The effectiveness of the procedure can vary, with some individuals experiencing significant and long-lasting pain reduction, while others may have a more limited or temporary benefit. Potential risks, though generally low, include infection, bleeding, and temporary or permanent numbness or weakness in the treated area. Electrodenervation is a minimally invasive technique that offers an alternative for patients suffering from specific types of chronic pain.
