Abstract
目的:分析椎弓根钉内固定术患者邻近节段退行性变( adjacent segment degeneration , ASD)的发生特点,探索其发病机制。方法选取2010-01至2013-12因脊柱疾病在接受手术治疗的患者72例为研究对象,均接受MRI和X线正、侧位检查,根据诊断标准计算ASD的发生率。分别采用视觉模拟评分法( VAS)和Oswestry功能障碍指数问卷表( ODI)对患者的疼痛和功能障碍情况进行评估。结果本组ASD发生率为26.39%。术前疼痛感明显,多种活动功能因疼痛而受到影响,VAS评分为5.20±1.19,ODI评分为0.43±0.12;末次随访时VAS评分为2.11±0.82,ODI评分为0.22±0.08,术前术后比较差异均有统计学意义(P<0.001)。结论椎弓根钉内固定术是引起ASD的原因之一,其机制可能与手术改变了邻近节段的受力和活动度变化有关。
