| 摘 要： | 本研究采用脊柱活动节段的三维有限元模型分析了脊柱在直立位、前屈位和后伸位的应力分布情况。结果表明上，椎弓根以及椎体后上方与椎弓根相邻部分为应力集中区域。这一结果提示胸腰椎爆裂性骨折的损伤机理与脊柱的应力集中有关。

| Abstract: | Stress distribution of the spine in upright, flexion and extension postion was analyzed using a three- dimensional finite element model of the spinal motion segment. The stress concentration was noted at the pedicle and the posterosuperior part of the vertebral body near the pedicle. The results indicate that stress concentration of the spine may be implicated in the biomechanical mechanism underlying thoracolumbar burst fractures. |
