Percutaneous endoscopic lumbar discectomy combined with platelet-rich plasma injection for lumbar disc herniation: analysis of clinical and imaging outcomes

Abstract

Abstract Objective To evaluate the clinical efficacy and imaging outcomes of percutaneous endoscopic lumbar discectomy (PELD) combined with platelet-rich plasma (PRP) for the treatment of lumbar disc herniation (LDH). Methods A total of 155 patients with LDH between January 2020 and June 2022 were retrospective analyzed, of which 75 underwent PELD with PRP and 80 underwent PELD only. Clinical functional scores and imaging data were compared. Clinical functional scores included visual analog scale of leg pain (VAS-LP) and back pain (VAS-BP), Japanese Orthopedic Association score (JOA), Oswestry Disability Index (ODI) and modified MacNab criteria. Imaging data included disc height index (DHI), spinal cross-sectional area (SCSA), disc protrusion size (DPZ), and ratio value of disc grey scales (RVG). Results Both groups showed clinical improvement, and VAS-LP, VAS-BP, JOA and ODI were significantly improved in the PRP group compared with the control group at 3, 6 and 12 months postoperatively (P 0.05). No serious complications occurred during the follow-up period. Conclusion PELD combined with PRP is a safe and effective method for treating patients with LDH. PRP injection was beneficial for delaying disc degeneration and promoting disc remodeling.
