Radiofrequency: Innovative Technology in Pain Treatment

Radiofrequency is a minimally invasive technique utilizing heat generated by radio waves to interrupt pain signals, offering prolonged relief for patients with chronic spinal pain.

How Does Radiofrequency Work?

The procedure involves inserting a special needle near the nerve transmitting the pain. Through this needle, radiofrequency waves generate controlled heat (70-80°C) causing a temporary lesion on the nerve, interrupting the transmission of pain signals to the brain.

The procedure is performed with fluoroscopy (real-time X-ray) or ultrasound guidance, ensuring precision and safety.

Indications for Radiofrequency

Lumbar or cervical facet pain (spinal arthritis)
Chronic sacroiliac pain
Lumbar discogenic pain
Occipital neuralgia
Pain after spinal surgery (post-laminectomy syndrome)

Advantages of Radiofrequency

Lasting relief (6 to 12 months or more)
Minimally invasive procedure
Performed on an outpatient basis
Rapid recovery (1-2 days)
Can be repeated when necessary
Reduces need for medications

Legal notice

Invasive or minimally invasive procedures should be indicated on a case-by-case basis after clinical evaluation. Risks, contraindications, and therapeutic alternatives should be discussed in consultation.
