【防疫医学论文】作者：江振华，陈向东，张烽，陶然【关键词】 脊柱胸腰段骨折测定TSRH用于脊柱侧前方内固定后强度、刚度和稳定性的力学性能。［ 方法 ］采用15具尸体胸腰段标本，5具为正常(NS)对照组，10具造成压缩性骨折后5具用TSRH行侧前方固定、另5具用Zplate固定作对照， 应用 实验应力 分析 法进行生物力学测试。［结果］应用TSRH内固定的脊柱应变、位移比正常脊柱对照组的应变、位移分别减小17%～20％和8％；固定后的强度和刚度与Zplate固定组相比仅小5％和5％，统计显示2种固定方法无显著性差异(P>005)。［结论］采用TSRH侧前方内固定后的脊柱不但强度、刚度和稳定性得到满足，而且在承载能力、脊柱的稳定性上优于正常对照组，与Zplate固定组相比无显著性差异，操作简便，价格低廉且临床应用疗效确切。

Abstract：［Objective］To determine the strength, rigidity and stability of the spine with TSRH lateralanterior fixation. ［Method］Fifteen fresh thoracolumbar specimen were used, 5 of them were used as control group, 10 of them were made compressed fracture and divided into two groups (each contained 5 specimen),TSRH and Zplate were used for lateralanterior fixation respectively. Biomechanical detection was carried on by the experimental stress analysis. ［Result］Compared with the con
