ABSTRACT Myelomeningocele is a common birth defect that is often accompanied by clubfoot deformity. Treatment of clubfoot associated with myelomeningocele traditionally has consisted of extensive soft-tissue release operations, which are associated with many complications. The purpose of the present study was to evaluate the early results of the Ponseti method for the treatment of clubfoot associated with myelomeningocele.
Sixteen consecutive patients with myelomeningocele (twenty-eight clubfeet) and twenty consecutive patients with idiopathic clubfeet (thirty-five clubfeet) were followed prospectively while being managed with the Ponseti method. The average duration of follow-up was thirty-four months for the myelomeningocele group and thirty-seven months for the idiopathic group. Clubfoot severity was graded at the time of presentation with use of the Diméglio system. The initial correction that was achieved, casting and/or bracing difficulties, recurrences, and subsequent treatments were evaluated and compared between the two cohorts by means of appropriate statistical analysis.
Eleven (39%) of the twenty-eight clubfeet in the myelomeningocele group were graded as Diméglio grade IV, compared with only four (11%) of the thirty-five clubfeet in the idiopathic group (p = 0.014). Initial correction was achieved in thirty-five clubfeet (100%) in the idiopathic group and in twenty-seven clubfeet (96.4%) in the myelomeningocele group (p = 0.16). Relapse of deformity was detected in 68% of the feet in the myelomeningocele group, compared with 26% of the feet in the idiopathic group (p = 0.001). Relapses were treated successfully without the need for extensive soft-tissue release surgery for all but four of the clubfeet in the myelomeningocele group and for all but one of the clubfeet in the idiopathic group (p = 0.16).
Our data support the use of the Ponseti method for the initial treatment of clubfoot deformity associated with myelomeningocele, although attention to detail is crucial in order to avoid complications. Longer follow-up will be necessary to assess the risk of late recurrence and the potential need for more extensive clubfoot corrective surgery in this patient population.

    ABSTRACT: Ponseti clubfoot treatment has become more popular during the last decade because of its high initial correction rate. But the most common problem affecting the long-term successful outcome is relapse of the deformity. Non-compliance with Ponseti brace protocol is a major problem associated with relapse. Although more comfortable braces have been reported to improve the compliance, they all have the same design and no significant changes have been made to the protocols. After refinement in the Ponseti method and emphasizing the importance of brace to parents, the relapse rate has been markedly decreased. Nevertheless, there are patients who do not have any recurrence although they are not completely compliant with the brace treatment, whereas other patients have a recurrence even though they are strictly compliant with the brace treatment. The aim of this article is to review the relapse of clubfoot and the function of the brace and to develop an individualized brace protocol for each patient by analyzing the mechanism of the brace and the biomechanical properties of muscles, tendons, and ligaments.

    ABSTRACT: Objetivo Analisar os resultados entre 1984 e 2004 em nossa instituição do tratamento cirúrgico de 69 pés equinovaros em 43 pacientes portadores de mielodisplasia segundo os critérios clínico e radiográfico. Métodos Estudo retrospectivo com análise de prontuário, radiografias e consulta com pacientes portadores de mielomeningocele que foram submetidos a correção cirúrgica de pés equinovaros. A técnica cirúrgica foi a liberação posteromediolateral (LPML)_radical associada ou não a talectomia. Resultados A média de idade na época da cirurgia foi de quatro anos e dois meses e o seguimento médio pós-operatório, de sete anos e dois meses. Foram encontrados resultados satisfatórios em 73,9% dos pés e insatisfatórios em 26,1% (p < 0,0001). Conclusão A deformidade residual no pós-operatório imediato está relacionada com resultados insatisfatórios e a abertura do ângulo de Kite (talocalcaneano) nos pés submetidos somente a LPML, além do posicionamento adequado do calcâneo, nos casos em que foi feita a talectomia, é o parâmetro radiográfico relacionado aos resultados satisfatórios.
