Result of a minimum 5-year follow-up after Ponseti serial casting in congenital idiopathic clubfoot

Abstract

© JOURNAL OF THE MEDICAL ASSOCIATION OF THAILAND| 2019 Background: Ponseti technique has become a standard treatment for congenital idiopathic clubfoot. Some cases require surgical release to achieve a pain-free, flexible and plantigrade foot. Objective: To evaluate the result of congenital idiopathic clubfoot with Ponseti serial casting in intermediate-term follow-up. Materials and Methods: The authors performed a retrospective cohort analysis of congenital idiopathic clubfoot patients who underwent primary treatment by Ponseti serial casting and who were followed-up for at least 5 years between January 2006 and December 2012. Demographic data, age at the beginning of treatment, Functional Rating System (FRS) clubfoot of Laaveg and Ponseti, talocalcaneal angle x-ray, and complication data were collected. Results: Thirty-three feet from 24 patients (14 males and 10 females) were included, with an average age at beginning of casting treatment of 6.18 weeks (range: 1 to 24). Average follow-up time was 5.94 years (range: 5.07 to 8.35). Mean FRS score was 95.35 (range: 89 to 98). Average talocalcaneal angle of AP and lateral view were 24.89° and 23.46°, respectively. Complications were found in 5 feet and recurrence occurred in 5 feet. Conclusion: Ponseti serial casting for treatment of congenital idiopathic clubfoot showed satisfactory FRS score at the 5-year follow-up.
