We studied dermatoglyphic imprints of patients with preaxial or postaxial polydactyly. Development of the additional finger is shown to be always accompanied by the corresponding finger triradius and basic line; postaxial polydactylies are characterized by the circular epidermal ridges around the rudiment of the sixth finger and the presence of the second additional triradius. On the basis of these data we suggest that major lines of the palm and finger triradii serve as landmarks denoting the borders of individual morphogenetic fields of fingers during their segregation from general morphogenetic field of the hand which is related to the polar system of coordinates.
我们研究了轴前型或轴后型多指畸形患者的皮纹印记。结果显示，额外手指的发育总是伴随着相应的手指三叉点和主线；轴后型多指畸形的特征是第六指原基周围有圆形表皮嵴，以及存在第二个额外三叉点。基于这些数据，我们认为手掌的主要纹路和手指三叉点可作为标志，在手指从与极坐标系统相关的手部整体形态发生场中分离出来的过程中，指示各个手指形态发生场的边界。
