The newborn baby's deformed foot is initially treated with casts. The tendons, ligaments, and bones are still quite flexible and easier to reposition. The foot is stretched into a more normal position and a light-weight cast is applied to retain the corrected position. The cast will be removed every week or two so the foot can be further stretched into better position and maintained with a new cast. This serial casting is continued for three or more months and is successful in at least 50% of cases. If the casts do not provide enough correction of the clubfoot, surgery is considered.
