摘要:
目的:分析寰枢关节紊乱症患者上颈椎的生物力学特征,探讨骨错缝在寰枢关节紊乱症发病中的作用。方法:基于1例寰枢关节紊乱症患者的影像资料构建有限元模型并验证其有效性,分析关节面、椎间盘、肌肉的应力情况,并与正常颈椎的有限元模型进行比较。结果:与正常模型相比,寰枢关节紊乱症模型的整体应力分布不均,模型右侧应力大于左侧; 寰枢关节紊乱症有限元模型的寰枢外侧关节、椎间盘、肌肉有明显的应力分布不均匀现象,偏歪侧的寰枢侧方关节、椎间盘后侧、头后大直肌止点处有明显的应力集中现象。结论:寰枢关节紊乱症会破坏上颈椎整体的力学平衡,导致关节面、椎间盘和肌肉的应力分布不均匀,可能导致颈痛和脊柱退变。
Abstract:
Objective:To analyze the biomechanical characteristics of the upper cervical spine in patients with atlantoaxial joint dysfunction syndrome.Methods:A finite element model of atlantoaxial joint dysfunction syndrome was constructed based on the imaging data of a patient and its validity was verified.The model was applied to simulate the movement of the cervical spine in all directions,and the stress maxima and stress distributions of the articular surface,C2/3 intervertebral disc and muscle were analyzed under physiological load.The stress status of the model was compared with that of the previously established normal finite element model of the upper cervical spine,so as to determine the influence of atlantoaxial joint dysfunction syndrome on the biomechanics of the upper cervical spine.Results:Compared with the normal model,the global stress distribution of the atlantoaxial joint dysfunction syndrome model was uneven,and the right side of the model was greater than the left side.In the finite element model of atlantoaxial joint disorder,there were obvious stress inhomogeneity in the lateral atlantoaxial joint,intervertebral disc and muscle,and obvious stress concentration in the lateral atlantoaxial joint on the oblique side,the posterior side of the intervertebral disc and the insertion of the major rectus muscle behind the head.Conclusion:Atlantoaxial joint disorders can destroy the overall mechanical balance of the upper cervical spine,resulting in uneven stress distribution of the articular surface,intervertebral disc and muscle,which may lead to neck pain and spinal degeneration.
