RESUMO
BACKGROUND: In the 1970s a conservative treatment for clubfoot (CF) deformity based on daily physiotherapy combining specific sequences was developed: the French functional method (FFM). Over time, the FFM technique has improved and additional measures have been introduced. The aim of this study was to report mid-term and long-term results of clubfeet treated conservatively by the FFM at birth. METHODS: All patients consecutively treated for clubfoot by the FFM between 1993 and 2010 were prospectively included. Initial severity was assessed by the Dimeglio classification. All patients were followed up by the same treating surgeon until skeletal maturity. Final assessment was performed using the International Clubfoot Study Group evaluation system (ICFSG). RESULTS: A total of 779 feet were included. Surgery was required in 41% of cases (mean age 2.0±0.1 years). The incidence of surgery significantly decreased after the introduction of percutaneous Achilles tenotomy (PAT) in 2000 (63.4% vs. 29.6%). At latest evaluation (mean follow-up 12±0.2 years), 86% of patients had excellent or good outcomes (mean ICFSG was 1.83±0.1). Mean ankle dorsiflexion was 10° in non-idiopathic CF and 12.1° in idiopathic CF. Eleven percent of the idiopathic clubfeet exhibited decreased ankle function (0-10°). There were no cases of overcorrection into excess ankle dorsiflexion or rocker bottom foot deformities. CONCLUSIONS: Current team was the funding institution of the FFM and several modifications were proposed over times to improve outcomes. Eighty-six percent of feet had excellent to good outcomes according to the ICFSG score, with minimal residual deformities (ankle dorsiflexion between 0° and 10°, calcaneal-thigh angle between 10° and 20°) or insufficient radiological correction (defined by talo-calcaneal angle between 10° and 20°) at latest follow-up.
RESUMO
Despite the presence of a considerable number of papers published in the international literature, talipes equinovarus keeps its secrets. Conservative methods of treatment are currently accepted as advantageous over surgery. Prediction of the future of a clubfoot after treatment is not possible, for this reason, a long-term follow-up is needful. A true Functional Method based solely on gentle manipulations has been used for more than thirty years. Its aim is to correct the deformity and to allow the child to walk without delay. The principle of this method is to distract joint contractures prior to progressive correction of the deformity. No selection is made regarding the severity of the deformity and its etiology. Family plays an important role in performing routine manipulations at home. Concerning this Functional Method, three main series have been published by our team, with excellent-good results accounting for up to 77%. We believe that our Functional Method of conservative treatment of clubfoot is an appropriate way for correction of the deformity and its stabilization.
