A club foot, or congenital talipes equinovarus (CTEV), is a
congenital deformity involving one foot or both. The affected foot
appears rotated internally at the ankle. TEV is classified into 2
groups Postural TEV or Structural TEV.

Without treatment,
persons afflicted often appear to walk on their ankles, or on the
sides of their feet. It is a common birth defect, occurring in about
one in every 1,000 live births. Approximately 50% of cases of
clubfoot are bilateral. In most cases it is an isolated dysmelia.
This occurs in males more often than in females by a ratio of 21. A
condition of the same name appears in animals, particularly horses.
