Progress on application of biomechanical experiment in the development of spinal internal fixation

生物力学实验在脊椎内固定中有着重要的意义。随着脊柱内固定系统的发展,生物力学实验早已应用于内固定及其使用方式的评价。本文对生物力学在脊柱内固定器械产生、发展和优化等过程中的应用进行综述,并与已经淘汰的内固定器械的生物力学性能进行比较,从而讨论生物力学实验的作用。生物力学实验对脊柱手术内固定器械的发展有着重要的作用,并为其临床使用提供指导,推动了整个脊柱外科的发展。目前,生物力学实验与有限元分析结合评价脊柱内固定器械是一个重要的趋势,通过将仿真结果与生物力学实验结合,将更加有效的评价脊柱内固定器械的使用。

Biomechanical experiment is of great importance in spinal internal fixation. With the development of spinal internal fixation system, biomechanical experiment has been applied into the evaluation of internal fixation and its application. Herein the applications of biomechanics in the production, development and optimization of internal fixation devices that are used frequently in clinic were reviewed. The biomechanical properties of the internal fixation devices that had been eliminated were compared with those of the devices which were most commonly used at present to discuss the role of biomechanical experiments in the development of spinal internal fixation. Biomechanical experiments play a critical role in the development of spinal internal fixation devices, provide guidance for the clinical use of spinal internal fixation devices and promote the development of the spine surgery. Nowadays, using biomechanical experiments combined with finite element analysis to evaluate spinal internal fixation devices is an important trend. By combining the simulation results with biomechanical experiments, spinal internal fixation devices can be more effectively evaluated.
