摘要

目的:通过CT测量求得国人成人腰椎管横径、矢径、关节突间距的数值以及相应的椎管指数,并探讨临床意义。方法:使用CT测量青岛地区100例(男女各50例)正常成人腰椎管L1~L5的径值。结果:腰椎管的横径平均径值性别间有显著差异(P<0.001)。椎管矢径性别间无明显差异(P>0.05)。关节突间距性别间有显著差异(L1~L3水平,P<0.01;L4~L5水平,P<0.001)。椎管横径与椎体横径的比值为0.52~0.55,关节突间距与椎管横径的比值为0.76~0.79,性别间无明显差异(P>0.05)。结论:CT测量腰椎管可以得出相对准确的腰椎管径值,为临床提供相关参考指标。

Abstract

Objective: To determine the normal dimensions of the lumbar spinal canal of Chinese people with CT, and to provide criteria for diagnosing spinal stenosis. Methods: CT scans of 100 normal adult Chinese people age ranged from 21~55 years were studied to obtain accurate data of lumbar spinal canal. The study population was composed of 50 men and 50 women. Six parameters were measured from each vertebral level, including the transverse and sagittal diameters of lumbar spinal canal, the width of vertebral bodies, and the interfacet distance. All the data were statistically analyzed for differences between men and women. Result: The results showed that for Chinese people there is a significant sex difference(P<0.01 or P<0.001) for transverse interpedicular distance(IPD), vertebral body width(VBW), and interfacet distance(IFD), but not for sagittal diameter(SD). The ratio between the width of the vertebral body and the mean transverse diameter of the lumbar spinal canal(canal/body ration; C/B) is 0.52~0.55. The ratio between IPD and IFD is 0.76~0.79. Conclusion: The normal diameter of the lumbar spinal canal in adult Chinese people can be obtained from CT. From these data, we can provide some parameters for diagnosing spinal stenosis.
