经皮内镜腰椎间盘切除术联合纤维环修复治疗腰椎间盘突出症的疗效OA

Objective To explore the efficacy of percutaneous endoscopic lumbar discectomy(PELD)combined with annulus fibrosus repair in the treatment of lumbar disc herniation(LDH).Methods The 36 patients with LDH were divided into a repair group(treated with PELD combined with annulus fibrosus repair,16 cases)and an unrepaired group(treated with PELD alone,20 cases)based on whether the annulus fibrosus was repaired.Perioperative indica-tors,LDH recurrence,pain VAS,ODI,and intervertebral space height were recorded.The modified MacNab scoring system was used to evaluate the efficacy.Results All patients were followed up for 48 months.The operation time of the repair group was longer than that of the unrepaired group(P＜0.05).There were no statistically significant differ-ences between the two groups in intraoperative blood loss,postoperative hospital stay,LDH recurrence rate,and the excellent and good rate of modified MacNab score at the last follow-up(P＞0.05).For the VAS of low back and leg pain,ODI:Both groups showed better results at the last follow-up than before surgery(P＜0.05);there were no sta-tistically significant differences between the two groups at the last follow-up(P＞0.05).At the final follow-up,the intervertebral space height in the repair group was greater than that in the unrepaired group(P＜0.01).Conclusions In the treatment of LDH,PELD combined with annulus fibrosus repair can not only achieve therapeutic effects sim-ilar to PELD alone,but also reduce the loss in lumbar intervertebral space height and slow down lumbar degenera-tion.
