Percutaneous Nerve Ablation with Radiofrequency (RF) is a modern, minimally invasive method applied to various chronic pain conditions. It can provide relief for individuals suffering from back pain, neck pain, joint pain, and in many cases, cancer-related pain.
There are two types of radiofrequency: continuous and pulsed, both applied under either CT or fluoroscopic guidance, after local anesthesia. In both procedures, an electrode is inserted into the target area through a specialized needle, which generates controlled heat. The final position of the electrode is confirmed by injecting a small amount of contrast dye and performing sensory and motor tests.
Continuous Radiofrequency: In continuous radiofrequency, the temperature reaches 80-90°C, causing the destruction of the target area and interrupting painful stimuli to the spinal cord and brain.
Pulsed Radiofrequency: In pulsed radiofrequency, the temperature reaches up to 42°C, inducing neuroconversion in the target nerve. The “damage” is not permanent, but the transmission of painful stimuli is significantly reduced.
