Pulsed radiofrequency neurotomy: A cure for back pain?

Pulsed radiofrequency neurotomy is a safe, effective treatment for back pain. It involves applying electrical current to a small area of nerve tissue to block the transmission of pain.

Pulsed radiofrequency neurotomy is done as an outpatient procedure. Your doctor inserts a needle near one or more nerves that are carrying the pain signal from your spine to your brain. A small electrode is threaded through the needle. Then, a pulsed electrical current is delivered through the tip of the electrode to the targeted nerve. This, in effect, "stuns" the nerve, which temporarily blocks its ability to transmit pain signals. The use of short bursts of electrical current — instead of a continuous flow — allows the tissue to cool between pulses, significantly reducing the risk of any tissue damage.

Pulsed radiofrequency neurotomy doesn't provide permanent pain relief, however. Eventually, the effects of pulsed radiofrequency wear off, and pain may return in as soon as three to six months. This procedure can be repeated, if necessary.

Pulsed radiofrequency neurotomy may be recommended for back pain that has not responded to more conservative treatment methods such as physical therapy and medications.
