颈椎间隙高度与椎体高度比值的测定及临床意义

Clinical valuation in measuring the ratio of height of cervical intervertebral space to inferior vertebral body

目的 :通过观察测量正常的X线侧位片 ,分别计算出各椎间隙高度与椎体高度的比值 ,为临床颈椎疾病的诊断和治疗效果评价提供客观准确的依据。方法 :观察正常的颈椎侧位片 2 2 2例 ,男 10 2例 ,女 12 0例 ,年龄18～ 5 6岁 ,其中小于 2 0岁 3例 ,2 0～ 2 9岁 65例 ,3 0～ 3 9岁 92例 ,40～ 49岁 5 1例 ,大于 5 0岁 11例。测量各椎间隙与椎体前缘、中份及后缘的高度 ,并求得椎间隙高度与下位椎体高度的比值 ,进行数据处理。结果 :男性椎间隙与椎体高度的比值 ,前缘为 0 2 72～ 0 3 3 8;中份为 0 474～ 0 5 2 8;后缘为 0 168～ 0 195。女性椎间隙与椎体高度间的比值 ,前缘为 0 2 70～ 0 3 3 3 ;中份为 0 471～ 0 5 0 9;后缘为 0 177～ 0 190。结论 :椎间隙与椎体间的比值比较恒定 ;各间隙的前缘、中份、后缘比值明显不同 ,中份最大 ,前缘次之 ,后缘最小。男性较女性的均值稍高 ,两者间无显著性差异 (P <0 0 5 )。本文结果对临床颈椎疾病的诊断与治疗效果评价提供了客观依据。

Objective:To discuss the ratio of height of cervical intervertebral space to height of inferior vertebral body for clinical diagnosis and treatment of cervical diseases.Method:Observed 222 normal cervical lateral X-ray sheets,including 102 males and 120 females.Measured the height of each intervertebral space and vertebral body at anterior,middle and posterior border.Obtained the ratio of intervertebral space to vertebral body.Result:The ratio of space to body was 0.272～0.338 (male),0.270～0.333 (female) at anterior border,0.474～0.528 (male) 0.471～0.509 (female) in the middle,0.168～0.195 (male) 0.177～0.190 (female) at posterior border.Conclusion:The ratio of height of space to body is even.The maximum ratio is the middle,and the minimus ratio is the posterior border.There is no different in ratio between male and female ( P<0.05 ).This quantitative analysis of the cervical vertebral space may provide anatomical basis for clinical imaging diagnosis of the cervical disease.
