摘要:

文题释义:
钩椎关节(Uncovertebral Joint):又称Luschca关节(Luschka joint),是下颈椎的独特特征,是位于椎体后外侧呈矢状位的嵴样隆起,由颈椎椎体上侧方的骨性突起——钩突与相邻上位椎体下侧方的斜坡关节构成,具有限制椎体间侧方移位的作用。
钩突:为钩椎关节中C3-C7椎体上侧方的骨性突起,该结构的增生、骨折等病变往往会压迫神经根、椎动脉、交感神经等结构,导致相应颈椎病症状的发生,因此针对该关节的研究也比较广泛。

背景:钩突增生常导致颈椎病发生,无需内固定的钩椎关节切除术具有重要意义,但尚存诸多问题。
目的:建立全颈椎(C0-T1)三维有限元模型,切除钩突不同范围后,探究颈椎关节突的应力变化特点和规律,为临床颈椎病的手术治疗提供理论依据。
方法:对40岁男性正常成人志愿者进行全颈椎螺旋CT轴位薄层扫描来获得原始数据,应用Mimics、GeomagicStudio、Hypermesh、Abaqus等软件技术建立C0-T1全颈椎三维有限元模型,在C5椎体上构建单侧钩突切除50%、100%和双侧钩突切除100%的3种模型组,然后加载相同力矩赋予前屈、后伸、左右侧屈和左右旋转6种工况,以观测切除不同范围钩突后颈椎关节突关节在不同状态下的应力与位移变化。
结果与结论:①通过构建全颈椎正常与切除钩突不同范围后的有限元模型,加载相同力矩后发现颈椎关节突的受力集中区由正常组的C6处上移至切除不同范围钩突组的C5处,得出关节突的受力随椎序增加呈现递增趋势;②应力集中区位于C5和C6处,整体呈尖峰状,不同程度的钩突切除会降低颈椎的稳定性,降低程度随切除范围增大而增大。

Abstract: BACKGROUND: Uncinate processes hyperplasia often leads to cervical spondylosis. Uncinate process resection without internal fixation is of great significance, but there are still many problems.  
OBJECTIVE: To establish a three-dimensional finite element model of the whole cervical vertebrae (C0-T1), and to explore the characteristics and laws of stress change after excising different ranges of the uncinate process, so as to provide a theoretical basis for the surgical treatment of clinical cervical spondylosis.
METHODS:  Raw data were obtained from spiral CT thin-section scans of 40-year-old male normal adult volunteers. Mimics, GeomagicStudio, Hypermesh, Abaqus and other software technologies were used to establish (C0-T1) full cervical three-dimensional finite element model. Models of 50% unilateral uncinate processes excision, 100% unilateral uncinate processes excision and 100% bilateral uncinate processes excision were constructed on the C5 vertebral body. After loading the same torque, six working conditions of flexion, extension, lateral flexion and rotation were assigned to observe changes of stress and displacement of the cervical facet joint in different states after the resection of the uncinate process.  
RESULTS AND CONCLUSION: (1) By constructing the finite element model of the normal cervical vertebrae and the uncinate process in different ranges, after loading the same torque, the stress concentration area of the cervical articular process was now moved up from C6 in the normal group to C5 in the different ranges of uncinate process excision groups. The stress of the nodal process increased with the increase of the vertebral sequence. (2) The stress concentration areas were located at C5 and C6, and the overall shape was sharp. The degree of resection of the uncinate process reduced the stability of the cervical spine, and the degree of reduction increased with the extent of resection.
