Simultaneous arthrography of the talocrural and talonavicular joints was performed on 32 normal feet from an autopsy material, and corresponding examinations were conducted clinically on 22 feet with no signs of deformity. The material comprised the age group 0 to 8 years. A linear correlation was observed between the length of the talus and the width of the talar trochlea. The radius and chord of the trochlear curvature increased proportionately with the length and trochlear width. These relationships were expressed as indices, by means of which the normal values for the radius and chord of the trochlea may be calculated for children up to 8 years of age. The mean value, standard deviation and tolerance limits were calculated for the central angle of the trochlear curvature and for the plantar and medial deviations of the talonavicular joint. These angles were found to be virtually constant between the neonatal period and the age of 8 years.
对32例取自尸检材料的正常足部进行了距小腿关节和距舟关节的同步关节造影，并对22例无畸形迹象的足部进行了相应的临床检查。材料涵盖0至8岁年龄组。观察到距骨长度与距骨滑车宽度之间存在线性相关性。滑车曲率的半径和弦长与长度和滑车宽度成比例增加。这些关系用指数表示，通过这些指数可以计算出8岁以下儿童滑车半径和弦长的正常值。计算了滑车曲率中心角以及距舟关节的足底和内侧偏斜的平均值、标准差和公差限度。发现这些角度在新生儿期至8岁之间基本恒定。
