How effective is interventional treatment for lumbar spinal stenosis?

Interventional treatment for lumbar spinal stenosis primarily refers to pulsed radiofrequency (PRF) therapy targeting the spinal nerve roots or dorsal root ganglia. This technique modulates neural activity directly to achieve pain relief.

This interventional radiofrequency procedure is particularly suitable for patients with poor general health who cannot tolerate open surgery—or those who prefer to avoid it. Postoperative pain relief typically ranges from 20% to 50%.

The degree of postoperative pain relief varies among individuals and depends on multiple factors—including preoperative severity of neural compression, baseline nerve condition, and duration of natural disease progression. Generally, a reduction in pain by more than 50% compared to preoperative levels is considered a favorable therapeutic outcome. The above information is for reference only; specific medications and treatments should be determined based on clinical evaluation and guidance from a physician.
