The aim of this study is to determine the effect of a new design of FAB type on compliance and treatment outcomes of idiopathic clubfeet treated by the Ponseti method. Very little literature exists on the effect of brace type or the difference between reported and actual at-home compliance, which is integral to the success of treatment with the Ponseti method. Eighty children less than 1 year of age will be enrolled in the study into two arms, using block randomization. These two groups will use two different designs of foot abduction brace (FAB). Outcomes will be measured by number of recurrences per group (using recasting and/or surgical procedures and Pirani score as indicators), time of recurrences (in months), compliance with brace wear using sensors and comparing the data with brace wear reported by parents, and parent satisfaction with FAB (measured on a modified Orthotics and Prosthetics User Sur vey). Enrollment will be on a rolling basis; subjects will be enrolled at their last cast application and followed for approximately 6 months. Recurrences, time of recurrence, parent satisfaction, and reported vs. actual compliance will be analyzed.
