A 1994 editorial by Ignacio Ponseti challenging the then-prevailing surgical approach to congenital clubfoot. Ponseti argues that serial manipulation and casting, applied with correct kinematic principles, can replace surgical joint release as primary treatment in otherwise normal infants. The editorial defines the technical principles of what became the standard-of-care Ponseti method.
When you see a newborn with clubfoot, the Ponseti method is the answer — and understanding why it works matters as much as knowing the steps.
The subtalar and Chopart joints do not have a fixed axis of rotation in clubfoot. The tarsal axes are shifted medially by the deformity, so pronating the foot (the classic error) makes things worse. Correct technique abducts the foot while maintaining supination, gradually walking the navicular, cuboid, and calcaneus laterally until eversion becomes possible.
Casting typically takes 2 months. After correction, brace compliance until age 4-5 years is non-negotiable. Relapse is a bracing problem, not a casting failure.
Ponseti explicitly warns that surgery is invariably followed by scarring severe enough in infants to produce stiff, damaged joints. The 25-42-year follow-up data showing equivalent functional outcomes with casting alone is the evidence that made this method the global standard.
