有限元分析法在脊髓损伤生物力学中的研究进展

脊髓损伤时的变化非常复杂，动物模型很难精确模拟损伤环境以及测量局部组织的生物力学属性，而有限元模型则可以通过分析脊髓组织的应力和应变分布，从生物力学角度为脊髓损伤的病理研究和治疗提供一个更为高效的方法。目前，有限元模型已被广泛应用，并与动物实验模型相辅相成。本文回顾了有限元法在脊髓损伤中的研究进展，对有限元法在脊髓本体建模、脊髓损伤的生物力学行为及其临床应用等方面的研究现况进行归纳及总结，以期为临床脊髓损伤问题提供更为全面的理论参考。

Research Progress of Finite Element Method in Biomechanics of Spinal Cord Injury

The changes in spinal cord injury are very complex. It is difficult for animal models to accurately simulate the injury environment and measure the biomechanical properties of local tissues, while the finite element model can analyze the stress and strain distributions of spinal cord tissues, thereby providing a more efficient and ethical approach to pathological research and treatment of spinal cord injury from the biomechanical perspective. At present, the finite element model has been widely used and complemented with animal experimental models. In this study, the research progress of finite element analysis in spinal cord injury was reviewed, and the research status of finite element analysis in spinal cord ontology modeling, biomechanical behavior of spinal cord injury and its clinical application was classified and summarized, so as to provide more comprehensive theoretical references for spinal cord injury in clinic.
