椎间盘源性腰痛的手术治疗

目的：研究腰椎间盘源性腰痛的手术疗效。方法：42例腰椎间盘源泉性下腰痛患者选择腰椎体间融合术进行治疗，其中12例行后路椎体间植骨融合椎弓根螺钉系统内固定术（posterior lumbar interbody fusion，PLIF），30例行前路髓核摘除植骨融合术（afront lumbar interbody fusion，ALIF）。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尺（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6～36个月，平均18个月。在12例行PLIF者中，11例术后腰腿病症状基本消失，1例仍有轻度腰痛，术前、术后VAS腰痛评分的差异有统计学意义（P〈0．01）。在30例行ALIF患者中，28例腰腿痛症状基本消失，术前、术后VAS腰痛评分的差异有统计学意义（P〈0．01）。行PLIF患者的融合率为90％，行ALIF患者的融合率93％。结论：严格掌握手术适应证，腰椎椎体间融合术是治疗腰椎间盘源性下腰痛的有效方法。

Objective To explore the curative effect of surgical treatment for lumbar discogenic low back pain. Methods Forty-two patients with lumbar discogenic low back pain were treated with disc excision and lumbar interbody fusion: 12 of them were treated with posterior lumbar interbody fusion (PLIF), 30 with afront lumbar interbody fusion (ALIF). The clinical results were evaluated by pre- and post-operative visual analogue scale (VAS), and the fusion rates of the lumbosacral spine were evaluated by X-ray. Results The average follow-up period was 18 months, ranging from 6 to 36 months. Low back pain basically disappeared in 11 patients treated with PLIF, with mild back pain in one patient; VAS after the operation decreased significantly in comparison with that preoperatively (P< 0.01). Low back pain basically disappeared in 28 patients treated with ALIF; VAS after the operation decreased significantly in comparison with that preoperatively (P< 0.01). The fusion rate was 90% in patients treated with PLIF, and 93% in patients with ALIF. Conclusion Disc excision and interbody fusion is effective in the treatment of lumbar discogenic low back pain, but the operation indications should be paid attention to.
