Least-invasive procedures can have names that not everyone is familiar with. For example, not many people without medical training know what a rhizotomy procedure is. However, if you experience back pain, rhizotomy surgery provides relief with the least invasive methods possible. Keep reading to learn about rhizotomy and endoscopic rhizotomy procedures.

What Does “Rhizotomy” Mean?
Doctors first used the word “rhizotomy” around 1910-1915. It comes from two root words: rhizo- (root) and -tomy (incision). The “roots” that the word refers to are the roots of your spinal nerves. That means when a doctor conducts a rhizotomy, they sever the nerves’ roots. Cutting the nerve roots removes the pain sensation. When back pain becomes chronic and severe, certain patients benefit from this procedure.
Radiofrequency Ablation and Endoscopic Rhizotomy
Two common types of rhizotomy are radiofrequency ablation and endoscopic rhizotomy. Both methods have the same goal, but they achieve that goal in different ways.
During a radiofrequency ablation procedure, the doctor uses heat to disable the nerve that causes the patient’s back pain. Radiofrequency ablation is a percutaneous procedure, meaning it involves a needle. This needle transfers a microelectrode that heats the targeted nerves. To pinpoint the nerve’s location, the doctor uses a fluoroscopic X-ray. Keep in mind that some people refer to this method simply as “rhizotomy,” so you may need to ask for clarification when talking about it.
Endoscopic rhizotomy involves using a small camera to find the affected location. The camera travels directly through the nerve branch, letting the doctor see the exact area of problem nerves. Once they find the location to operate, they make a small incision on the nerve roots.
Which Method Works Better?
At Spine INA, we perform endoscopic rhizotomy procedures when radiofrequency ablation fails because it relieves pain more effectively . Consider these important differences:
- A doctor conducting an endoscopic rhizotomy can directly see the nerves instead of relying on an X-ray.
- Many patients feel relief immediately after endoscopic rhizotomy. Meanwhile, it can take a month to feel the effects of radiofrequency ablation.
- Radiofrequency ablation reduces pain for up to one year, but the benefits of an endoscopic rhizotomy can last for three to five years.
