经皮激光椎间盘减压术治疗椎间盘源性腰痛的疗效评价

目的：探讨经皮激光椎间盘减压术（ PLDD）治疗椎间盘源性腰痛的疗效。方法回顾分析2011年6月～2013年6月临床诊断为椎间盘源性腰痛患者共28例。术后随访3～24个月，平均12．5个月，比较术前与末次随访疼痛视觉模拟评分、功能障碍评分变化，按改良MacNab功能评价标准评价患者对治疗的主观满意度。结果与术前相比，术后VAS评分降低（3．7±1．3），差异有显著性（P＜0．01），术后ODI评分降低（13．7±5．0），差异有显著性（P＜0．01）；无神经根损伤、大出血、死亡病例，显效6例，有效17例，无效5例，满意度82．1％．结论经皮激光椎间盘减压术为治疗椎间盘源性腰痛安全、有效的方法，值得推广。

Efficacy of Percutaneous Laser Disc Decompression Treatment on Discogenic Low Back Pain

Objective To evaluate the efficacy of percutaneous laser disc decompression treatment on disco-genic low back pain .Methods Retrospective analysis including 28 cases of patients with a clinical diagnosed discogenic low back pain from June 2011 to June 2013 was performed .Patients were followed up 3~24 months ,an average of 12 .5 months,and the score changes of VAS ,ODI were observed preoperative and final follow-up.According to the modified MacNab criteria ,satisfaction of the treatment was evaluated .Results Compared with the preoperative ,Postoperative VAS score decreased（3.7 ±1.3）,and there were significant differences （P〈0.01）.Postoperative ODI score decreased （13.7 ±5.0）,there were significant differences （P〈0.01）.No nerve root injury,bleeding or deaths appeared ,there were 6 cases being significantly effective in treatment ,17 cases being effective ,5 cases being ineffective ,and the satisfaction was 82.1%.Conclusion Percutaneous laser disc decompression is a safe and effectivefor method for the treatment of disco -genic low back pain .
