Talonavicular arthrodesis for the acquired flatfoot in the adult.

Abstract

The acquired painful flatfoot in the adult is a syndrome that commonly is disabling and progressive. Patients should benefit from a surgical technique that can provide correction of the major deformities and lasting stability with limited surgical morbidity. Twenty-nine patients treated with a talonavicular arthrodesis for this disorder were followed up a minimum of 12 months and an average of 26 months. Twenty-five patients (86%) were satisfied with no or minor reservations and achieved good or excellent results. A talonavicular arthrodesis, by addressing the instability at its focal point, appears to achieve these goals with one surgical procedure.
