椎间孔镜经椎板间隙入路手术治疗腰椎间盘突出症

目的：评价椎间孔镜经椎板间隙入路髓核摘除术治疗腰椎间盘突出症的短期疗效。方法：对2009年4月至2010年4月采取椎间孔镜经椎板间隙入路手术治疗的27例腰椎间盘突出症患者进行回顾性分析。其中男20例,女7例;年龄21～69岁,平均41.8岁;12例采取＂由内向外＂髓核摘除术,15例采取＂由外向内＂髓核摘除术。采用ODI（Oswestry Disability Index）指数以及改良MacNab标准评定临床疗效。结果：＂由外向内＂术式中有1例因出血视野不清中止手术、1例转为椎间盘镜下髓核摘除,其余25例均顺利完成手术。其中20例获得随访,平均随访时间为（18.0±2.5）个月。末次随访时ODI为（13.0±20.5）%,与术前的（75.4±7.8）%比较有统计学差异。按照改良MacNab标准：优7例,良9例,可1例,差3例;疗效差的病例中,1例于术后3个月行开窗手术,2例需口服药物治疗。结论：椎间孔镜经椎板间隙入路治疗腰椎间盘突出症,突出物较大、将硬膜囊和神经根明显挤向一侧的患者宜采用＂由外向内＂的方式,如术前经反复保守治疗、突出物相对较小者则宜采用＂由内向外＂的方式;合理选择均可以达到有效减压,获得满意临床疗效。
