RESUMO

In congenital clubfoot, residual deformities are not well-documented and they may change depending on different treatments. To identify the treatment that provides better outcome at maturity, we studied the computed tomography of two cohorts of patients affected with congenital clubfoot who were treated using two distinct protocols. Forty-seven clubfeet were treated according to the traditional protocol of our hospital and 61 were treated according to the Ponseti technique. The normal feet of the unilateral deformities served as controls. All patients were followed to skeletal maturity. The ankle torsion angle and the declination angle of the neck of the talus were higher than normal but different only in patients treated with the traditional method. The calcaneocuboid angle was lower but only in patients treated with the Ponseti method. The shape of the talar joints was altered in many feet regardless of protocol. The CT images suggest the modifications of the torsion angle of the ankle, the declination angle of the neck of the talus, and the calcaneocuboid angle at maturity are related to the treatment protocol followed. The Ponseti manipulative technique provided better anatomical results in comparison to our traditional technique.
