What is radiofrequency ablation for lower back pain?

Radiofrequency (RF) ablation for back pain is a treatment that uses heat produced by RF energy to damage the tiny nerves responsible for sending pain signals to the brain. With the connections interrupted, people may experience months of symptom relief. Certain people with chronic back pain originating in the facet and sacroiliac joints may be candidates for RF ablation,

To perform RF ablation, a needle with an imbedded wire is used to deliver energy from the needle’s tip to the treatment site while people are sedated. The procedure heats a small area around the targeted nerve, while just a few millimeters away, body temperature is normal.

Epidural Injections and Lower Back Pain
Radiofrequency ablation, also known as RFA, can help patients with chronic lower back and neck pain, and pain associated with the degeneration of joints from arthritis.

RFA uses heat to temporarily block the nerves that send pain signals from the facet joints of the spine to the brain. Although temporary, the effects can last for up to a year or more in some cases. High frequency waves are used to create a lesion in the nerve, with the aim of preventing the transmission of pain.

The majority of patients treated with RAF experience some degree of pain relief, but your doctor will determine if the minimally invasive procedure is right for your chronic lower back pain.

The main side effect of RFA is discomfort, swelling or bruising that generally goes away in a few days. There is a slight risk of infection or bleeding at the insertion site.
