About This Procedure
Prior to the procedure, the patient is asked to lie on their stomach and an intravenous line (IV) is initiated. A local anesthetic is used to numb targeted areas above the spine, and the patient may feel slight pressure as the doctor inserts each needle.
The doctor tests the sensory nerves, asking the patient about the various sensations. A temperature probe is placed in each target location, only long enough to interrupt the sensory nerve pathways, and a medication is injected (local anesthetic and low-dose steroid) before removing each needle.
Following the procedure, the patient is asked to lie on their back for 30 minutes.
Results should be apparent within two to four weeks. While this treatment typically offers long-term pain relief (three months or more), the extent of relief varies from patient to patient.
What is radiofrequency ablation?
Radiofrequency ablation helps decrease pain by interrupting the sensory nerve pathways using a temperature-monitored probe.
During the procedure, heat generated by radio waves is used to target specific nerves and temporarily interfere with their ability to transmit pain signals. The radio waves are delivered via needles inserted through the skin above your spine. Imaging scans are used during radiofrequency rhizotomy to help the doctor position the needles precisely.
Who is a candidate for radiofrequency ablation?
Radiofrequency ablation may not work for everyone. Before patients can be scheduled for this procedure, the source of their symptoms is often verified through a series of spinal injections and/or discography tests. Radiofrequency ablation may not be an effective solution for those whose symptoms arise from several sources.
