[摘要] 目的 评估髓核摘除并棘突间动态稳定系统治疗腰椎间盘突出伴失稳症的效果。 方法 对16例腰椎间盘突出伴失稳症患者行髓核摘除、置入Wallis系统固定治疗，术前与术后末次随访时进行VAS及JOA评分，在X线片上测量手术节段与相邻节段活动度，根据中华医学会骨科分会脊柱学组手术疗效标准进行疗效评估。 结果 16例获得18～24个月随访，平均20.3个月，优15例，良1例，差0例；术后末次随访时VAS和JOA评分与术前比较均有统计学差异(P<0.05)，手术节段活动度术后小于术前(P<0.05)，相邻节段活动度与术前相比无统计学差异(P>0.05)。 结论 腰椎后路开窗髓核摘除联合应用Wallis系统治疗腰椎间盘突出伴失稳症，效果满意。
