颈前路手术治疗颈椎病的有限元研究进展

Progress of Finite Element Study on Anterior Cervical Surgery for Cervical Spondylosis

不同颈前路手术治疗颈椎病对患者颈椎生物力学特征的影响因手术方法而异,但临床上较难精细地测量颈椎各部分或内植物的力学属性。因此,有限元法被广泛应用于颈前路手术的研究,可以通过计算机精确分析不同部分的应力和应变分布,为研究不同颈前路术式的生物力学特征提供便利。本文回顾了有限元法在颈前路手术中的研究进展,对有限元研究在融合或非融合术式、混合手术及微创手术等方面的现况进行归纳总结,以期为不同颈前路手术的选择提供生物力学角度的理论参考。

The impact of various anterior cervical surgeries on biomechanical properties of cervical vertebrae varies depending on the specific surgical techniques employed.However,accurately measuring the mechanical characteristics of individual parts of the cervical vertebrae or implants within them in a clinical setting can be challenging.As a result,the finite element method is commonly utilized in studies on anterior cervical surgery,allowing for the precise analysis of stress and strain distributions in different areas of interest through computer simulations.This method facilitates the study of biomechanical properties associated with different anterior cervical surgical approaches.This review discusses the progress of finite element analysis in anterior cervical surgery,summarizes current research findings on fusion and non-fusion procedures,hybrid surgeries,and minimally invasive techniques,so as to provide theoretical references for the selection of different anterior cervical surgical interventions from a biomechanical perspective.
