Pretty much, yes. We know that the incidence of clubfoot is about 1:1000 in an average U.S. Population. It is higher within certain ethnic groups, such as japanese (1:500) and hawaiian islanders (1:250). However, it is more difficult to predict the incidence along particular family lines. Many children are born with clubfoot in which there is no specific history of the deformity in recent family generations.
