Radio Frequency Ablation

Radiofrequency ablation (RFA) is a medical procedure used to treat chronic pain by interrupting the pain signals transmitted by specific nerves in the body. It is a minimally invasive technique that provides relief from long-lasting pain.

During RFA, a doctor uses a specialized device that emits highfrequency radio waves. These waves create heat that is directed toward the nerves responsible for transmitting pain signals. The goal is to heat the nerve tissue to a point where it becomes inactive, thereby reducing or eliminating the pain.

To begin the procedure, the patient is given a local anesthetic to numb the area around the targeted nerves. Then, the doctor inserts a small needle-like electrode near the nerves under the guidance of imaging techniques, such as fluoroscopy or ultrasound.

Once the electrode is correctly positioned, a low-voltage current is passed through it, creating heat at the tip of the electrode. This heat selectively damages or destroys the targeted nerve tissue, disrupting its ability to transmit pain signals. The heat generated is carefully controlled to ensure that surrounding healthy tissues are not affected.

The entire RFA procedure typically takes about 30 minutes to an hour, depending on the number of nerves being treated. After the procedure, the patient may experience some discomfort or soreness at the treatment site, but this usually resolves within a few days.

The effects of RFA can vary from person to person. Some individuals may experience immediate pain relief, while others may notice a gradual reduction in pain over a few weeks. The duration of pain relief can also vary, ranging from months to years, depending on the individual and the underlying condition. It’s important to note that RFA is not a permanent solution for chronic pain. Over time, the treated nerves may regenerate, and the pain may return. In such cases, the procedure can be repeated if necessary.

RFA is commonly used to treat conditions like arthritis-related joint pain, facet joint pain, and certain types of nerve pain. It is generally considered safe, with a low risk of complications. However, as with any medical procedure, there are potential risks and side effects that your doctor will discuss with you.

Overall, radiofrequency ablation offers an effective option for managing chronic pain by selectively disrupting the function of specific nerves. It can provide significant pain relief and improve the quality of life for individuals experiencing long-lasting pain.
