Lumbar biacuplasty is a treatment that applies heat to the annulus of the lumbar discs, which separate the vertebra from the back, with the main goal of ablating the neurons that generate pain sensations within the body.   The treatment is designed specifically to reduce chronic back pain that is often caused by intervertebral discs. This treatment is often used because it can destroy the pain's nerves without damaging any nearby tissues.   For patients who are suffering from symptoms of discogenic pain, lumbar biacuplasty will use a different approach by creating a large, reproducible lesion in the posterior and posterolateral annuli. The nerves will be deactivated in large volumes of the posterior disc without any risk of excessive heating of the tissue.
