目的 观察经后路椎间植骨融合治疗腰椎间盘突出症的临床疗效和并发症。方法 将76例腰椎间盘突出症患者纳入研究对象,均采用经后路椎间植骨融合治疗,观察手术相关指标、机体功能、手术并发症等情况。结果 76例患者手术时间(121.4±17.2)min,术中出血量(132.8±20.4)ml,术后引流量(71.1±12.2)ml,术后卧床时间(5.9±1.3)d,疼痛数字评分指数(numerical rating scale,NRS)(3.2±0.6);术后3、6、9、12个月 Oswestry功能障碍指数ODI分别是28.8±4.1、25.5±2.9、19.4±3.2、13.8±2.0,均明显低于手术前;手术过程中出现硬脊膜撕裂6例(7.89%),神经损伤2例(2.63%),术中cage位置不佳6例(7.89%);术后发生cage移位或深陷7例(9.21%),切口感染2例(2.63%)。结论 经后路椎间植骨融合治疗腰椎间盘突出症的临床疗效肯定,但存在手术并发症发生的可能性,应引起足够的重视。

Objective To analyze efficacy and complications after posterior approach intervertebral fusion in treatment of lumbar disc herniation. Methods Lumbar disc herniation patients underwent conventional posterior approach lumbar intervertebral fusion. Operation related index, body function, and complication were observed. Results In 76 patients, operation time was (121.4±17.2) h, intraoperative blood loss (132.8±20.4) ml, postoperative drainage (71.1±12.2)ml, postoperative bed time (5.9±1.3) d, NRS score (3.2±0.6).After 3 months, 6 months, 9 months and 12 months postoperatively,Oswestry disability index ODI 28.8±4.1、25.5±2.9、19.4±3.2、13.8±2.0 were lower than that before the operation.Dural tear occurred in 6 cases (7.89%), nerve damage in 2 cases (2.63%), intraoperative cage poor position 6 cases (7.89%), postoperative cage shift 7 cases (9.21%), and infection of incision 2 cases (2.63%). Conclusions Posterior approach lumbar intervertebral fusion for treatment of lumbar disc herniation has sure clinical curative effect, but there is the possibility of surgical complications;clinical enough attention should be paid.
