Metrical length and width parameters of the first through third ray metacarpals and phalanges are presented for four samples of adults of both sexes drawn from radiographs of the Ten State Nutrition Survey (1968-1970). Radiographic measurements were obtained with the aid of a digitizer and computer translation program. The establishment of ranges of variation among these samples allows their use in clinical diagnosis, for example of syndromes via pattern profile analysis. Proportional analyses of hand metrics can now be extended to include widths of the first three rays as well as lengths, and data for such a purpose are now available for American blacks. Mexican-Americans, and Oriental-Americans in addition to American white groups. Examples of intersample variation are given; the need to consider such variation in clinical contexts is emphasized.
通过对1968 - 1970年十州营养调查的X光片进行分析，获取了四个成年男女样本的第一至第三掌骨和指骨的长度和宽度参数。X光片测量借助数字化仪和计算机翻译程序完成。确定这些样本的变异范围有助于将其应用于临床诊断，例如通过模式轮廓分析诊断综合征。手部测量的比例分析现在可以扩展到包括前三根手指的宽度和长度，目前除了美国白人组外，美国黑人、墨西哥裔美国人以及亚裔美国人也有相关数据。文中给出了样本间变异的例子，并强调了在临床环境中考虑这种变异的必要性。
