制定了评估人体腰椎间盘中矢状切面大体形态的五级分级方案。三名观察员对一系列具有广泛形态的68个椎间盘进行分类的能力确立了分类的全面性。三个独立的观察员测试的重复性的程序，通过分配等级盲目复制图像的68个光盘从15个脊椎。观察者内范围为87 - 91%。三对观察者之间的一致性分别为61%、64%和88%，两个较低的值归因于一名观察者的偏差。对于I级至V级，指定等级和平均等级之间的一致性分别为85%、92%、68%、90%和76%。除III级外，不一致主要归因于一名观察员的偏倚。随着年龄的增长，等级的增加，以及15个脊柱中的14个内的所有椎间盘等级范围很窄的发现，都证明了该方案的生物学可信度。
A five-category grading scheme for assessing the gross morphology of midsagittal sections of the human lumbar intervertebral disc was developed. The ability of three observers to categorize a series of 68 discs with a wide spectrum of morphologies established the comprehensiveness of the classification. Three independent observers tested the reproducibility of the procedure by assignment of grades blindly to duplicate images of 68 discs taken from 15 spines. The intraobserver ranged from 87 to 91%. The interobserver agreement was 61, 64, and 88% for the three pairs, the two low values being attributable to the bias of one observer. The agreement between the assigned and average grades was 85, 92 , 68, 90, and 76% for Grades I through V, respectively. Except for Grade III, the disagreements were attributable mainly to the bias of one observer. Both the increase in the grade with age and the finding that all the discs within 14 of 15 spines had a narrow range of grades demonstrated the biologic credibility of the scheme.
