Gait kinematics in children with Ponseti treated clubfeet, relapse clubfeet and healthy controls using the Oxford Foot Model

Abstract

A clubfoot is characterized by a three-dimensional deformity with an equinus, varus, cavus and adduction component. Nowadays the Ponseti method is the preferred treatment for clubfeet, aiming to achieve a normal appearing, functional and painless foot. The reoccurrence of clubfoot components in treated clubfeet, a relapse, is a known problem in clubfoot patients. 3Dgait analysis can be used in assessment of foot function and residual deviations in gait or possible relapses. \nGait analysis is frequently used to analyse differences in gait between clubfoot and healthy controls. However, the usage of multisegment foot models is, although of importance considering the characteristics of the clubfoot, rare. In order to capture the full multi-planar and multi-joint nature of a clubfoot, it is highly important to implement multi-segment foot models in gait analysis. In order to improve treatment of individual relapse clubfoot kinematics differences in clinical relevant functional outcomes should be known.
