Abstract
Objectives: We retrospectively investigated the clinical materials to seek the factors that lead to relapse after using the Ponseti method.
Methods: We retrospectively reviewed all children with congenital clubfoot treated with the Ponseti method in our hospital from June 2008 to June 2013. The data included the following factors: age, gender, initial Pinari score, number of casts, number of feet (unilateral or bilateral), age at the first casting, age of mother, tenotomy, walking age, and compliance with using bracing. All investigations were conducted in conformity with ethical standards. This study was approved by Guilin Peoples' Hospital Ethics Committee.
Results: In this study, there were 148 cases (164 ft) in total that underwent the Ponseti method, with the follow-up period at least 5 years. Of them, 64 children presented with left side, 58 with right side, and 26 with bilateral cases. This study included 75 males and 73 females; sex did not affect the outcomes. The mean age of the first casting was 2.50 ± 2.15 months. The average initial Pirani score was 4.98 ± 1.33, and the average number of casts was 5.71 ± 2.28 times. The mean age of mothers at birth was 25.81 ± 2.38 years old. The walking age of children was at a mean of 14.83 ± 1.18 months. Forty-nine cases could not tolerate using braces, namely the rate of noncompliance in this study was 33.1%. Tenotomy was performed on 113 ft (76.4%). The average follow-up period was 7.27 ± 1.29 years (from 5 to 10 years). The rate of relapse was 21.6% (32 cases) at the end of the follow-up. The rate of relapse in the noncompliance with using bracing group was significantly higher compared to the compliance group .
Conclusion: The initial Pirani score, compliance with the foot abduction brace and the age at the first casting are three independent factors for relapse in clubfoot.
