Abstract:: Abstract: 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.
