摘要 目的:探讨Bioflex动态稳定系统在多节段腰椎退行性疾病中的应用价值。方法回顾性分析2010年1月至2012年6月收治的腰椎退行性疾病患者23例,其中男14例,女9例;年龄44~67岁,平均57岁。单节段病变15例,多节段病变8例。椎板减压后根据退变程度选择椎间盘部分切除或椎体融合器进行融合的方法,采用Bioflex动态固定系统稳定脊柱后路,观察疼痛视觉模拟评分( visual analog scale,VAS)、Oswestry功能障碍指数( Oswestry disabil-ityindex,ODI)、脊柱节段活动范围(range of motion,ROM)。结果术后随访12~40个月,平均(22±9)个月。统计显示术前VAS评分为(7.2±1.7)分,末次随访为(2.6±1.1)分;术前ODI为(71.4±17)%,末次随访为(21.3±11)%。非融合节段ROM术前为(8.1±1.9)°,末次随访为(2.8±1.1)°;邻近上位椎体ROM术前为(7.9±1.7)°,末次随访为(7.2±1.8)°;邻近下位椎体ROM术前为(8.4±2.1)°,末次随访为(7.9±1.9)°。与术前比较末次随访VAS、ODI差异均具有统计学意义( P〈0.05)。手术前后非融合节段腰椎活动度差异均具有统计学意义( P〈0.05),邻近椎体节段活动度较术前无明显统计学差异( P〉0.05)。结论初步研究表明Bioflex动态固定系统是治疗腰椎退行性疾病的一种安全、有效的方法,远期效果有待进一步观察。
