PurposeTreatment of idiopathic clubfoot with the Ponseti method is now standard, but predicting relapse can be difficult. Most experts recommend bracing to the age of four years, but this can be challenging for families, and may not be necessary in all patients. The purpose of this study is to compare patterns of bracing and age of relapse to help determine if predictable patterns exist.MethodsThe 70 patients with idiopathic clubfoot treated initially with the Ponseti technique who had relapse of their clubfoot were identified. Relapse was defined as a return to casting or surgery due to recurrent deformity. Data collected included demographics, treatment and brace adherence. Patients who sustained initial relapse before the age of two years were compared with those who sustained initial relapse after the age of two years.ResultsIn total 56% (39/70) had their initial relapse prior to age two years while 44% (31/70) were after age two years. Of the patients who relapsed prior to the age of two years, 28% (11/39) were adherent with bracing while 72% were non-adherent. For patients who initially relapsed after age two, 74% (23/31) were adherent with bracing while 26% were non-adherent (p < 0.001). Of those who had initial relapse prior to age two, a subsequent relapse was seen in 69% (27/39).ConclusionPatients with idiopathic clubfoot who experienced recurrence prior to age two years are significantly more likely to be non-adherent with bracing than those who sustain recurrence after age two. After initial relapse prior to age two, bracing adherence does not affect likelihood of subsequent recurrence.
