Objective: The Ponseti method for the treatment of club foot has been shown to be effective in children up to one year of age. However, it is not known whether it is successful in older children. In this prospective study, we used Ponseti method in club foot after walking age; that are neglected or undergone an insufficient previous treatment.

Materials and Methods: From 2003 to 2005 we treated and followed-up 37 feet of 30 patients. All the club foot deformities corrected by the method described by Ponseti, with minor modifications. The mean age at presentation was 21 months (12–72 months) and the mean follow-up was 26 months (16–32 months). 21 feet had previous conservative and surgical treatments. The mean applied cast count that used for this method was 5.4 (4 – 8 cast). After cast treatment we performed achilotomyfor 15 feet, achiloplasty for 20 feet and achiloplasty and posterior capsulotomy for 2 feet. All the patients evaluated before and after treatment by the Dimeglio classification.

Results: Before treatment 35 feet were grade 3 and 2 feet were grade 4, and after the treatment 11 feet were grade 0, 26 feet were grade 1. All the patients deformities were corrected and the treatment results were statically significant (p=0.0001). Patients distincted in two groups according to their age at the beginning of the treatment. 20 feet were younger than 20 months and 17 feet were older than 20 months. All the patients younger than 20 months had grade 3 deformity before treatment and 19 feet improved grade 1 and 1 foot improved to grade 2 after this method. In patients older than 20 months 15 feet were grade 3 and 2 feet were grade 4. and after this treatment method in this group 13 feet were improved to grade 1 and 4 feet were improved to grade 2. Patients older than 20 months had worse results for the components of varus, medial rotation of calcanopedal block and adductus thant the other group. And difference in these groups were significant.

Conclusion: We conclude that the Ponseti method is a safe, effective and low-cost treatment for idiopathic club foot presenting after walking age.
