【摘要】 ［目的］研究后路椎体间融合加椎弓根固定治疗腰椎间盘源性腰痛的手术疗效。［方法］36例腰椎间盘源性下腰痛，选择后路椎体间植骨融合（posterior lumbar interbody fusion，PLIF）加椎弓根螺钉系统内固定术。分别于术前、术后对病人的腰痛情况进行视觉疼痛自我评定（visual analogue scale，VAS）评分，同时评估术后腰椎融合率。［结果］术后随访时间8～28个月，平均16个月。36例行PLIF治疗者,33例术后腰腿痛症状基本消失，3例仍有轻度腰痛，术前、术后VAS腰痛评分，差异有统计学意义（P＜0.01）。行PLIF患者，融合率为90％。［结论］严格掌握手术适应证，后路腰椎椎体间融合术（PLIF）加椎弓根内固定是治疗腰椎间盘源性下腰痛的有效方法。

Abstract：［Objective］To explore the curative effect of lumbar discogenic low back pain treated with posterior lumbar interbody fusion(PLIF)and transpadicular instrumentation.［Method］Thirtysix patients with lumbar discogenic low back pain were treated with disc excision,lumbar interbody fusion and transpedicular instrumentation.The clinical results were evaluated by preand postoperative VAS（visual analogue scale）,and the fusion rates were evaluated by Xray of the lumbosacral spine.［Result］The average period of followup was 16 months,ranging from 8 to 28 months.Low back pain basically disappeared in 33 patients treated with PLIF,mild back pain occurred in 3 patients;the V……
