Early effectiveness of unilateral biportal endoscopic discectomy combined with annulus fibrosus suture in the treatment of lumbar disc herniation

To analyze the early effectiveness of unilateral biportal endoscopic discectomy (UBED) combined with annulus fibrosus suture in the treatment of lumbar disc herniation (LDH). The clinical data of 19 patients with LDH treated with UBED and annulus fibrosus suture between October 2020 and October 2021 were retrospectively analyzed. There were 12 males and 7 females with an average age of 39.1 years (range, 26-59 years). The operative segment was L in 13 cases, and L , S in 6 cases. The mean disease duration was 6.7 months (range, 3-15 months). Preoperative neurological examination showed that muscle strength, sensation, and tendon reflex weakened or disappeared in varying degrees. Single annulus fibrosus suture (14 cases) or anchor assisted annulus fibrosus suture (5 cases) was selected according to the location of annulus fibrosus tears. Visual analogue scale (VAS) score was used to assess the low back and leg pain before operation and at 3 days, 3 months, and 6 months after operation. Oswestry disability inde
