| Abstract: | This article reviews the application of finite element method in spine biomechanics during the last three years. Major progress in both finite element model improvement of detailed microstructure, personalized vertebrae parameter weights, new accurate calibration method, automated modeling approach and spine biomechanics-related applications including implant design assessment, inter-vertebral disc biomechanics, biomechanics of abnormal spinal structure, dynamic simulation are classified and summarized. Future development of finite element method being applied in trauma mechanism, surgery simulation and drug evaluation is also discussed. |
