The cause of congenital clubfoot is not very clear, from modern medicine, some scholars believe that it may be related to the following factors: 1, heredity, some reports say that it is an autosomal dominant inheritance, we observed in the clinic, if his father and mother have this disease, he tends to develop the probability of nearly 30 times higher than other children on average, this is the genetic factors; 2, may be related to some congenital factors The foot of the fetus is basically turned inward within five weeks of embryonic life, and after five weeks, the foot will slowly turn back to normal, when the original embryonic quality is not enough, so that the transformation cannot continue, which may also be a cause of congenital clubfoot; 3. When his foot is in some special position, it causes local muscle ischemia and hypoxia, some may be due to low amniotic fluid and small size of the uterine cavity, the fetus is squeezed in the uterine cavity, or is subject to related compression, causing clubfoot. These are probably some of the causes of clubfoot that we know of so far.
