腰骶段椎间盘与相应椎体的应用解剖

Applied anatomy for intervertebral discs in the lumbosacral vertebrae and their related bodies

目的 为临床诊断椎间盘疾患提供参数。方法 对 31例正常男性脊柱第 1腰椎至第 1骶椎间 15 5个椎间盘及其相应的 186个椎体上下面的矢径、横径、斜径进行了测量和比较 ,同时对其周围毗邻结构进行了观察。结果 椎间盘各径均大于其相应椎体各径 ,且自上而下逐渐增大 ,获得了腰骶段周围毗邻结构的观察结果。结论 提示结果与各椎骨间所负体重逐渐增加相适应 。

Objective To offer parameters for diagnosis the diseases of intervertebral discs.Methods This present paper deals with diameters of 155 intervertebral discs and 186 bodies taken from the first lumbar vertebrae to the first sacral vertebrae of 31 normal adult males′ vertebral column.The sagittal,transverse and oblique diameters of all these intervertebral discs and bodies were measured and contrasted,and observe their neighborhood tissue.Results It was found that the diameters of intervertebral discs are greater than those of their related bodies and were gradually increased from top to bottom and get the results of observation.Conclusion The results accord with the ascending weight of each vertebral body and provide anatomic data for clinic.
