Clubfoot is a condition noted at birth, in which the foot is not flexible and appears turned in. This can be very successfully treated with the Ponseti method, which includes a period of weekly casting followed by bracing.
Casting will begin in the first few months of life, and it usually takes an average of 5 casts each week to correct the foot. In most cases, a small cut is made in the back of the heel (called an Achilles tenotomy), prior to the last cast, which stays on for 3 weeks.
After casting, the baby is transitioned into a special pair of shoes with a bar, which connects them and holds each foot a specific angle. This is worn for 23 hours per day for 12 weeks, and then transitioned to nighttime only wear until at least age 3.
