椎弓根内固定术是目前临床上治疗胸腰椎骨折的常用术式.脊柱的生物力学是内固定器设计和研制的基础,也是评价其固定稳定性和实用价值的标准.因此,运用生物力学原理全面分析脊柱的病理力学改变及内固定器的作用原理,对于合理使用内固定器以取得最佳矫形和固定效果具有重要意义.现对胸腰椎骨折椎弓根内固定的生物力学研究进行简要综述.%Pedicle screw fixation is often performed in thoracolumbar fractures. The biomechanics of spinal is not only the basis for designing the fixation devices but also a standard to evaluate the stability and practical value of fixation devices. Therefore,biomechanical analysis of the pathological changes in spine and the mechanical fixation of the action principle are quite necessary. Here is a brief review of biomechanics research progress in pedicle screw fixation of thoracolumbar fracture.
