5. Study Description

Brief Summary
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.
Detailed Description
A superiority study, phase III, prospective, single-center, randomized in parallel groups and conducted in a single-blind manner, with evaluation by a blind outcome assessor. Patients will be randomized to one of two treatment groups: Experimental group (surgery and periradicular administration of PRF) or Control group (reference treatment, surgery alone).
