摘要
目的:观察不同方向及不同大小提扳力的旋提手法对颈椎关节突关节软骨的应力影响.方法:基于验证过的颈椎C3～C7三维有限元模型,模拟颈椎左侧旋提手法,分别加载中立位、不同定位方向、相同提扳力+不同定位方向以及相同定位方向+不同大小提扳力,比较C3～C7各节段双侧关节突关节软骨峰值应力情况.结果:在中立位时,最大峰值应力集中于双侧C6～C7节段;在不同定位方向时,最大峰值应力集中于旋转同侧C4～C5节段;在不同定位方向联合相同提扳力以及相同定位方向联合不同大小提扳力时,最大峰值应力均集中于旋转对侧C6～C7节段.结论:不同方向及不同大小提扳力的旋提手法对颈椎关节突关节软骨应力集中节段均有不同影响.
Abstract
Objective:To observe the efficacy of rotation-traction manipulation with different directions and different forces on the stress of cervical facet articular cartilage.Methods:Based on the verified three-dimensional finite element model of cervical spine C3-C7,the left cervical spine rotation-traction manipulation was simulated,and the neutral position,differ-ent positioning directions,the same lifting force combined with different positioning directions,and the same positioning di-rection combined with different lifting forces were respectively loaded,and the peak stress of bilateral facet articular carti-lage at each segment of C3-C7 was compared.Results:At the neutral position,the maximum peak stress was concentrated in bilateral C6-C7 segments.The maximum peak stress is concentrated in the C4-C5 segment on the same side of rotation at different orientation directions.When the same lifting force is combined with different positioning directions and differ-ent lifting forces are combined with the same positioning directions,the maximum peak stress is concentrated in the C6-C7 segment on the opposite side of the rotation.Conclusion:The different directions and sizes of the lifting forces with ro-tation-traction manipulation have different effects on the stress concentration segments of the articular cartilage of the cer-vical facet.
