Abstract

The purpose of this study was to analyze the alterations in frontal-plane hindfoot motion and in plantar pressure in 2 patients (3 feet) after talonavicular joint fusion. Three-dimensional movement of the hindfoot was recorded by using an electromagnetic motion analysis system. The results indicated that frontal-plane hindfoot motion of the operative foot was substantially reduced during the stance phase of walking. In addition, each patient's frontal-plane hindfoot angle while in the resting standing position was decreased and plantar pressure under the medial longitudinal arch was reduced after surgery.
