The development of the human foot from the eighth to the twenty-first intrauterine week was studied in 147 specimens. The results documented a stage of "physiologic club foot" characterized by a medial deviation and plantigrade orientation of talar neck and head during the ninth week. At the same time, the calcaneus assumes a position of varus with the forefoot in adduction. By the eleventh week, the foot assumes a normal position. All findings during the stage of physiologic club foot closely resemble those of the intrinsic type of club foot.
在147个标本中研究了人类足部从子宫内第8周到第21周的发育情况。结果记录了一个“生理性马蹄内翻足”阶段，其特征为在第9周时距骨颈和头部向内侧偏斜并呈足底位。同时，跟骨呈内翻位，前足内收。到第11周时，足部恢复正常位置。生理性马蹄内翻足阶段的所有发现与先天性马蹄内翻足的内在类型非常相似。
