Abstract：Objective To analyze the treatment mechanisms of thoracolumbar spine compression fracture by hyperextension based on 3D finite element method. Methods Totally 10 cases with compression fracture of T11～L2 were selected into our study. Based on the 210-layer consecutive CT DICOM3. 0 format images,a 3D finite ele-ment model of hyperextensive manipulative reduction for compression fracture of T11 ～L2 was built after the effect of model was confirmed. The analysis of the result of the shape and the stress distribution of the model was carried out based on the results. Results Through the 3D finite element model construction of thoracic and lumbar vertebral compression fracture,the simulated appearance was clear and intuitive,which had mechanical structure stress analy-sis ability. After given manipulative reduction, the compressed vertebra developed hyperextension. At the same time,the results in the manipulative reduction principle and the classic mechanical test were the same,which meant that 3D finite element method was durable,precise and laconic. Conclusion The 3D finite element analysis is more accurate and reliable than the traditional research methods with easy analysis and simple operation,which is worthy of further application and promotion.
