The Ponseti technique involves sequential clubfoot correction by abduction, supination, and finally dorsiflexion. Although shown to be effective, correction progression has not been examined. The Dimeglio/Bensahel classification system was used to analyze heel equinus, varus, midfoot rotation, adduction, posterior crease, medial crease, and cavus initially and after each casting. From 2000 to 2008, 123 patients (185 feet) with idiopathic clubfeet, aged below 60 days, without prior treatment were grouped by number of casts required. Successive castings achieved goals of reducing cavus and medial crease first, then gradually correcting midfoot rotation, adduction, and heel varus. Unexpectedly, heel equinus improved simultaneously with midfoot variables, as well as with final casting.
