摘　　要：目的　探讨胸腰椎楔形指数在椎体的压缩性骨折诊断中具有重要意义 ,确定国人指数的正常范围 ,方能提高诊断的准确性。尤其在骨质疏松引起非暴力性骨折诊断中显得更为重要。方法　本文通过 10 0例正常人胸腰椎楔形指数研究 ,表明各椎体间存在差异 ,但与性别无关。结果　椎楔形指数 95 %上限 T1 2 - L2 >15 % ,T5- T1 1 及 L3,L4<15 %。结论　提示各椎体应单独制定压缩性骨折的标准。Objective Vertebral wedge index is very important in the diagnosis of vertebral fracture,especially the non violent fracture resulting from osteoporosis,and in that sense,it is necessary to delimitate the normal range of the wedge index for improvement in the accuracy of diagnosis.This paper aims at the normal thoracolumbar spinal fracture index.Methods One hundred samples were studied.Results The data on wedge index indicate that the vertebrae differ with one another,but there is no significant distinction between the two sexes.The upper limit of 95% CI for the wedge index from T12 to L1 is more than 15%,but it is less than 15% from T 5 to T 11 and from L 3 to L 4.Conclusion This disparityin vertebrae implies that we should set standard for each vertebra in order to diagnose the vertebral fracture correctly.
