Foot abduction brace in the Ponseti method for idiopathic clubfoot deformity: torsional deformities and compliance

The Ponseti method has shown to be effective in treating idiopathic clubfoot deformity. Application of a foot abduction brace is crucial to long term outcome. Compliance and possible effect on femoral anteversion and tibial torsion were assessed in 20 children with an average bracing period of 33 months. Nineteen patients were compliant with the bracing protocol and highly satisfied with the treatment protocol. Ultrasound measurement of femoral anteversion (40.5 degrees) and tibial external torsion (38.4 degrees) of the affected side were within the normal range. Range of motion of the ankle joint in all clubfeet resulted in an average dorsiflexion of 27.5 degrees. Among our patient group, the method proved to be highly accepted by almost all families, with excellent functional results. Application of the foot abduction brace did not result in pathological changes of femoral anteversion or tibial torsion.
