The deformity will often be apparent at birth but occasionally does not present until the child starts walking. A deformity of the foot and ankle is normally referred to as ‘talipes’. Other terms may qualify the word talipes, e.g. varus (inverted heel), valgus (everted heel) and equinus (foot plantar-flexed). Deformities of the toes are dealt with under toe lesions (p. 426).
