摘　　要：回顾近年来有限元法（finite element method,FEM）在腰椎椎间融合术与人工椎间盘置换术生物力学中的研究进展,并对其应用前景进行展望。通过归纳整理,得出FEM在腰椎椎间融合术与人工椎间盘置换术生物力学中的研究要点是手术方案的优化选择、植入器械的性能评价和临床手术的效果预测。最后依据当前的研究要点和发展方向,对FEM在个性化手术模拟、弹性内固定性能评价和新型术式效果预测等方面的应用前景进行展望。通过对FEM在腰椎椎间融合术与人工椎间盘置换术生物力学研究中的应用进展进行回顾和展望,以期为临床腰背痛疾病的手术治疗提供更加全面和系统的理论指导。The research progress of finite element method（ FEM） applied in biomechanics of lumbar fusion and artificial lumbar disc replacement was reviewed and its prospect was forecasted. The main research directions of FEM are optimal selection of operation plans before the surgery,performance evaluation of implanted devices and prediction of postoperative outcomes. Based on the recent research progress,the application prospects of FEM in simulation of personalized surgery,evaluation of elastic implants and postoperative prediction of novel operation method were discussed. By reviewing and prospecting the application of FEM in biomechanical research of lumbar fusion and artificial lumbar disc replacement,the purpose of this paper is to provide theoretical references and practical guidance for the treatment of lumbar diseases in clinic.
