正常胸_(12)腰_1椎体高度比与其压缩骨折的对照分析

The comparative analysis of height ratio between normal vertebral body and compressed fracture cases in twelfth thoracic and first lumbar vertebra

目的:测量正常胸12腰1椎体前后高度,统计出高度比的取值范围,对高度比与压缩性骨折进行影像学对照。方法:随机抽取126份青壮年腰椎侧位片,测量并计算胸12腰1前后高度之比值。结果:本组年龄及性别两个样本P值均>0.05,无显著性差异。测得胸12前后高度比为0.813±0.003;腰1为0.810±0.007。结论:胸12腰1前后高度比对椎体压缩骨折具有影像学诊断价值。

objective： To measure the height of anterior and posterior part of 12th thoracic vertebrae （T12） and the 1st lumbar （L1） ,then calculate the range of height ratio. Compared the normal height ratio with compressed fracture of the TI2＆L1. Methods：To get the image of T12＆L1 from youths. In random from 1996 to 2002,measured and worked out the height ratio of the front part to the latter of T12＆L1. Results：The p values of the age and sex samples in this group,there were no outstanding difference （P〉0.05）. The VaIue in T12 was 0. 813＋0. 003. That was 0. 810＋0. 007 in L1. Conclusion：There was image diagnosis vaIue to the compressed fracture using the hcight ratio of the anterior part to the posterior partof T12＆L1.
