成人第12胸椎及第1腰椎椎体前缘和后缘高度比率正常值的应用价值

Application value of normal range of anterior and posterior edge height ratio in adult T_(12) and L_1 vertebral body

目的探讨在腰椎侧位X线平片上成人T12及L1椎体轻度压缩性骨折的诊断依据。方法选择2011年3月至2012年9月该院拍摄的成人腰椎正侧位X线片(含T12,)220例,腰椎侧位片80例为对照组,另选择同期拍摄的成人腰椎正侧位X线片(含T12)轻度压缩性骨折24例、L1轻度压缩性骨折36例作为观察组,比较两组T12及L1椎体的前、后缘高度,将所测数据进行统计学处理。结果观察组成人T12及L1轻度压缩性骨折楔形程度均大于对照组(P<0.05)。结论成人T12及L1椎体前、后缘高度比值的正常范围可作为判断T12及L1椎体有无轻度压缩性骨折的衡量指标。

Objective To explore the diagnosis basis of mild compression fracture of adult T12 and L1 vertebral body in X-ray plain film.Methods 220 cases of frontal and lateral X-ray films of adult lumbar vertebra（including T12） and 80 cases of lateral X-ray plain film of lumbar taken in these hospitals from March 2011 to September 2012 were selected as the control group.Contemporaneous the frontal and lateral X-ray films of adult lumbar vertebra（including T12） in 24 cases of mild lumbar compression fracture and 36 cases of mild L1 compression fracture were selected as the observation group.The heights of anterior edge and posterior edge in T12 and L1 vertebral body were measured and compared between the two groups.The measured data were performed the statistical process.Results The vertebral wedge degree of adult T12 and L1 mild compression fracture in the observation group was greater than that in the control group（P0.05）.Conclusion The normal range of the anterior and posterior edge height ratio in adult T12 and L1 vertebral body may be used as the measurement index for judging T12 and L1 mild compression fracture.
