Thoracic facet radiofrequency neurotomy (facet rhizotomy) is used to treat nerve pain in the upper back after other forms of treatment have failed. The procedure “turns off” the specific nerve that carries information about pain. The treatment provides pain relief for about a year, but can last much longer for some people.

Introduction
Thoracic facet radiofrequency neurotomy (facet rhizotomy) is used to treat nerve pain in the upper back after other forms of treatment have failed. The procedure “turns off” the specific nerve that carries information about pain. The treatment provides pain relief for about a year, but can last much longer for some people.
Anatomy
Your spinal cord is located within the protective spinal canal. The spinal cord extends from the brain and is a major part of your nervous system. Spinal nerves extend from the spinal cord and travel out of the spine to exchange nerve signals with your brain about specific parts of your body. In particular, the medial nerves carry nerve signals about facet joint pain.

Treatment
A thoracic selective nerve root block is an outpatient procedure. You will wear a gown for the procedure and be positioned lying face down on a table. You will receive relaxation medicine before your procedure begins. Your upper back area will be sterilized and numbed with an anesthetic medication.
Your doctor will use a live X-ray image (fluoroscopy) to carefully insert and guide a needle-like tube (cannula) to the affected medial nerve. A small wire-like electrode (radiofrequency electrode) is inserted through the cannula. To ensure the cannula is in the correct position, a very mild electrical current is delivered through the electrode to the nerve. The nerve will briefly conduct pain signals and cause a muscle twitch, confirming that the correct nerve is targeted. Next, numbing medication is delivered to the nerve in preparation for the treatment. Heat is delivered through the electrode to the nerve. The heat creates a lesion on the nerve. The heat disrupts the nerve’s ability to send signals about pain. At the end of the procedure, the cannula and electrode are removed. The process can be repeated for additional nerves that require treatment.
It usually takes three to four weeks for the treated nerves to completely die. You may experience pain until the treated nerves are dead.
Thoracic facet radiofrequency neurotomy typically results in pain relief for about 9 to 14 months, or longer. About 50% of people experience pain relief for as much as two years. A small percentage of people do not experience any pain relief from the procedure. Over time, the nerves will grow back (regenerate). Some people will not experience pain again. If you experience pain, the procedure may be repeated.
