A photographic measuring technique has been used to study the lengths of the upper arm and forearm in normal British girls. The data are presented graphically, and show: 1. Ellipses which include 97 per cent of normal subjects when upper arm length is plotted against forearm length. 2. Variation of upper arm length and forearm length according to age. 3. Variation of upper arm length in relation to forearm length, irrespective of age. 4. Variation of upper arm length and forearm length in relation to sitting height, irrespective of age. The charts collectively provide a means of defining the exact nature of abnormalities of growth in the arms or of differences between populations. They provide a new aid to the classification of disorders involving abnormal growth of the arms.
一种摄影测量技术已被用于研究英国正常女孩上臂和前臂的长度。数据以图表形式呈现，结果显示：1. 当绘制上臂长度与前臂长度的关系图时，包含97%正常受试者的椭圆。2. 上臂长度和前臂长度随年龄的变化。3. 与前臂长度相关的上臂长度变化，与年龄无关。4. 与坐高相关的上臂长度和前臂长度变化，与年龄无关。这些图表共同提供了一种确定手臂生长异常的确切性质或不同人群之间差异的方法。它们为涉及手臂异常生长的疾病分类提供了新的辅助手段。
