为探讨下腰段椎间盘高度变化的规律在腰椎间盘突出症X线诊断中的意义，对80例腰椎间盘突出症病人和30名无腰腿痛症状的青年学生进行CT检查，并对其X线平片腰椎间隙高度及高度比值进行了测量和分析对比。结果显示，观察组92.5%的病人L4～5椎间隙后缘高度小于或等于L3～4椎间隙，对照组仅6.7%；观察组93.8%的L4～5椎间隙前后高度之和小于或等于L3～4椎间隙前后高之和，对照组为0；观察组85%的L4～5和L3～4椎间隙前后高度比值不同，而对照组则全部相同。表明腰椎间隙变窄后绝大部分存在着椎间盘突出，下腰段X线检查，如L4～5椎间隙后高小于或等于L3～4椎间隙，或出现椎间隙前高小于或等于后高，或各椎间隙高度的比值不相同，则是椎间盘突出的重要征象。

In order to master radiographic diagnostic method of prolapse oflumbar intervertebral disc based on the law of height change of low lumbar intervertebral disc. Methods. X-ray height measurement of lumbar intervertebral space and CT examination were given to 80 cases of prolapse of lumbar intervertebral disc(observed group) and 30 cases of young students without wrist-leg pain(control group), then compare two groups in intervertebral space height and height ratio. Results. ① 92.5％ cases of posterior border height of L4～5 intervertebral space in observed group and only 6.7％ in control group were not larger than that of L3～4; ② 93.8％ cases of sum of anterior and posterior height of L4～5 intervertebral space in observed group and zero in control group were not larger than that of L3～4; ③ 85％ cases of ratios of anterior and posterior height of L4～5 and L3～4 intervertebral space in observed group were different, but they were same in control group. Conclusion. Prolapse of lumbar intervertebral disc mostly existed in after narrowing of lumbar intervertebral space. Carry out radiographic examination of low lumbar region. The following were important signs of prolapse of intervertebral disc: posterior height of L4～5 intervertebral space was not larger than that of L3～4, anterior height of intervertebral space was not larger than posterior height, or each ratio of intervertebral space height was different.
