Clubfoot is a birth defect where one or both feet are rotated inwards and downwards. The affected foot, calf and leg may be smaller than the other. In about half of those affected, both feet are involved. Most cases of clubfoot are not associated with other problems. Without treatment, people walk on the sides of their feet, which causes problems with walking. Diagnosis of clubfoot may occur at birth or before birth during an ultrasound exam.
