Abstract
1. An anatomical study of congenital club foot in various stages of foetal development is presented, and the literature is reviewed.
2. The most striking finding was deformity of the talus and in particular a change in its angle of declination.
3. That deformity was present in feet whose deformity could not be corrected by gentle manipulation; it was absent in feet whose deformity could be so corrected.
4. Abnormality of the tendon and insertion of the tibialis posterior muscle was found in most cases.
5. Speculations are advanced concerning the nature and cause of the talar deformity.
