Study on the clinical effect of percutaneous transforaminal endoscopic discectomy combined with annulus fibrosus repair in the treatment of single-segment lumbar disc herniation in young and middle-aged patients

To explore the clinical effect of percutaneous transforaminal endoscopic discectomy (PTED) combined with annulus fibrosus repair in the treatment of single-segment lumber disc herniation (LDH) in young and middle-aged patients. Ninty-six patients with single-segment LDH admitted to Baoding First Central Hospital from March 2021 to November 2022 were selected in the retrospective study. The patients were divided into endoscopic group and combined group according to different surgical methods. The surgical conditions, VAS score and ODI score the two groups of patients were compared, as well as the postoperative review results. There were 50 patients in the endoscopic group the average operation time was 43.68 ± 10.77 minutes, the average intraoperative blood loss was 35.38 ± 10.02 ml, there were seven cases of surgical segment recurrence and 10 cases of postoperative intervertebral instability at the surgical segment. There were 46 patients in the combined group, the average operation time was 52.26 ± 8.39 minutes, the average intraoperative blood loss was 39.23 ± 9.02ml, there was one case of surgical segment recurrence and two cases of surgical segment intervertebral instability. The operation time (t=-4.328, P
