摘要
OBJECTIVE: To introduce the technical key points of lumbar annulus fibrosus suture under full-endoscope and analyze the clinical efficacy of full-endoscopic lumbar discectomy and annulus fibrosus suture. METHODS: A total of 50 patients with non contained lumbar disc herniation treated with full-endoscopic lumbar discectomy and annulus fibrosus suture in our department between January 2018 and November 2018 were included. Full-endoscopic single-stitch suture through transforaminal approach or double-stitch suture through interlaminar approach was selected according to lesion level. The lumbar MRI and CT were reexamined on the second day and 3 months after surgery to evaluate the completeness of the discectomy and the adequacy of nerve decompression respectively. The patients were followed up on the second day, 3 months, 6 months, and 1 year after surgery for pain relief using visual analogue scale (VAS, 100 -point scale). The patients were followed up at 3 months, 6 months, and 1 year postoperatively for the recovery of lumbar spine function using Oswestry Disability Index(ODI). At the 1-year follow-up, the Macnab standard of lumbar spine function was evaluated, and the recovery of nerve root function (sensory, muscular and reflex) was recorded. RESULTS: >0.05). CONCLUSION: Full-endoscopic lumbar discectomy and annulus fibrosus suture are safe and effective techniques for minimally invasive spinal surgery, which can reduce the recurrence rate of lumbar disc herniation after full endoscopic lumbar discectomy.
