腰椎管成形术在多节段腰椎管病变中的应用

目的:研究腰椎管成形术联合椎弓根钉内固定系统,治疗双节段腰椎管狭窄症及腰椎管内肿瘤等复杂性腰椎管病变的手术技巧和临床疗效。方法:对2005年3月～2009年12月间,我院应用腰椎管扩大成形术,治疗双节段腰椎管狭窄症及腰椎管肿瘤患者共112例,其中双节段腰椎管狭窄症84例,腰椎管内良性肿瘤28例。结果:随访6个月～4年,本组术后优:87例,良:15例,优良率91.1%。结论:腰椎管成形术联合椎弓根钉内固定,同时关节突关节、棘突间动态固定治疗腰椎管病变,既能保持脊柱的即时稳定性,又保持了脊柱的持久稳定性,同时减少了腰椎生物力学改变,减少了术后骨质缺如和出血量,缩短了手术时间,对预防医源性椎管狭窄具有积极作用,对复杂而多节段腰椎管病变是一种较为理想的术式。
