腰椎间隙高度与椎体高度比值的测定及其临床意义

Measurement of the ratio of lumbar intervertebral height to vertebral body height and its clinic value

目的 测量正常的腰椎X线侧位片，为临床腰椎疾病的诊断及治疗效果评价提供客观标准的依据。方法 抽取正常腰椎侧位片380例，测量各椎间隙与上位椎体前、中及后缘的高度，并求得椎间隙与上位椎体高度的比值，进行数据处理。结果 男性比值：前缘为0、442～0．607，中份为0、284～0．417，后缘为0．203-0．324。女性比值：前缘为0．440-0．605，中份为0．280～0．414，后缘为0．201～0．321。结论 各椎间隙与上位椎体间的比值较恒定。男性较女性的均值稍高，两者间差异无显著性（P〈0．05）。

Objective To provide reference data for diagnosis and treatment of lumbar disease with measurement of the ratio of lumbar intervertebral height to vertebral body height in X-ray films. Methods 380 cases of normal lumbar films were recruited. The intervertebral height and upper adjacent vertebral anterior middle and posterior height were measured, and the ratio of lumbar intervertebral height to vertebral body height was calculated, and the data were processed. Results In males, the ratio was 0. 442 - 0. 607 anterior, 0. 284 - 0. 417 middle and 0. 203 - 0. 324 posterior. In female, the ratio was 0. 440 - 0. 605 anterior, 0. 280 - 0. 414 middle and 0. 201 - 0. 321 posterior. Conclusions The ratio of lumbar intervertebral height to vertebral body height was constant in every segment. It is a little high in male than female, which has no statistical difference （ P 〈 0. 05 ）.
