摘要
目的研究人工椎间盘植入术后邻近节段的运动范围及椎间盘应力改变。方法将接触问题引入生物建模,建立正常全颈椎有限元模型,模拟C5/6椎间植骨融合和C5/6人工间盘植入,分析两种状态下其相邻节段的运动范围及椎间盘的应力改变。结果(1)所建立模型包含了韧带、关节囊及其他软组织结构,而且真实细腻,准确度高;(2)椎间植骨融合术后邻近椎间隙运动范围增加,相应椎间盘应力明显增大,上位节段髓核与纤维环的应力约增加70%,而下位节段髓核与纤维环应力约增加40%;(3)人工间盘植入后颈椎运动范围除仅后伸受限(P(0.05)外,邻近节段椎间盘应力增加不超过10%。结论植入的颈椎人工间盘可在一定程度上降低相邻椎体节段的应力,且有利于改善颈椎的活动度。
