有限元分析法在脊柱生物力学中的研究进展

Research progress of finite element method in spine biomechanics

摘要:

人体脊柱的解剖结构错综复杂,脊柱与周围神经和动脉等的位置十分接近,各个椎体之间应力的多变,韧带、肌肉连接的相互作用力的不同,为科研研究带来了巨大的挑战。基于有限元法的背景,归纳和整理了近几年有限元法在建模方式、临床手术、力学分析等方面的研究进展,再结合研究进展探讨有限元法在脊柱生物力学应用中的不足。本文通过对近年来有限元在脊柱生物力学研究的文献进行回顾与展望,为临床医师的临床工作提供参考。

Abstract:

The anatomical structure of the human spine is complex, the position of the spine is very close to the peripheral nerves and arteries, the stress between each vertebral body is changeable, and the interaction force between ligaments and muscles is different, which brings great challenges to scientific research. Finite element analysis plays an extremely important role in the study of spinal biomechanics in orthopaedics. With the continuous improvement of computer technology and the continuous updating and application of finite element analysis software, the exploration of spinal biomechanics is further. This paper collects and collates the literature of finite element method in spinal biomechanics research in recent years to provide reference for clinical work of clinicians.
