One of the most common birth defects (1 in 1000 live births).
Can be identified on prenatal ultrasound (true-positive rate 83%).
Exam demonstrates a hindfoot in varus, a forefoot that is adducted, and an ankle in equinus.
Prognosis is good with a nonoperative approach using the Ponseti method of treatment (bracing and serial casting).
Achilles tenotomy is used in >90% of cases to improve dorsiflexion.
Tibialis anterior tendon transfer and posteromedial release and tendon lengthening are further surgical treatment options.
