The prevalence of post-surgical lumbar neuropathic radiculopathy is approximately 30%. Poor response to the treatments recommended for neuropathic pain, namely antidepressants and/or gabapentinoids, requires the development of new techniques to prevent this chronic pain. Certain well-tolerated techniques, such as the administration of plasma enriched with platelets and fibrin (PRF), are increasingly used in regenerative medicine for their anti-inflammatory and analgesic properties. Thus, a periradicular intraoperative application of PRF may have an analgesic effect on the intensity of residual postsurgical neuropathic pain after disc herniation surgery.
