ABSTRACT
PURPOSE:
We assessed the pattern of relapse as well as the correlation between the number of casts required for correction and Pirani and Dimeglio scores at presentation, and age at presentation. We hypothesized that the Ponseti method would be effective in treatment of relapsed clubfoot as well.METHODS:
We evaluated 115 idiopathic clubfeet in 79 children presenting with relapse following treatment by the Ponseti method. The mean age was 33.8 months with mean follow-up of 24 months. All patients were assessed for various patterns of relapsed deformities. Quantification of deformities was done using the Pirani and Dimeglio scores. All relapsed feet were treated by a repeat Ponseti protocol.RESULTS:
Non-compliance to a foot abduction brace was observed to be the main contributing factor in relapse, in 99 clubfeet (86%). Combination of three static deformities (equinus, varus and adduction) together was observed most commonly (38.3% feet). Overall, relapse of equinus deformity was noted most commonly followed by adduction. A painless plantigrade foot was obtained in all 115 feet with a mean of five casts. In all, 71 feet (61.7%) underwent percutaneous tenotomy. A total of 15 feet (13%) required tibialis anterior tendon transfer. Re-relapse rate in group 1 was 21% compared with 12.6% in group 2 and overall 16.5%.CONCLUSION:
We conclude that the Ponseti method is effective and the preferred initial treatment modality for relapsed clubfeet. Surgical intervention should be reserved for residual deformity only after a fair trial of Ponseti cast treatment. Regular follow-up and strict adherence to brace protocol may reduce future relapse rates. Further research is required to identify high-risk feet and develop individualized bracing protocol.
