Dynamic plantar pressure measurements in children with tarsal coalition

Tarsal coalition is a congenital foot anomaly seen in childhood. It results in a rigid flatfoot deformity. Radiographic studies are needed to confirm the diagnosis. Characterization of this foot deformity during normal gait was done using the Emed plantar pressure system (Novel Electronics Inc, St Paul, USA). The hindfoot demonstrated higher than normal peak pressure and increased peak pressure on the third metatarsal area with an increased plantar contact area on the midfoot. The center of pressure line had a normal trajectory.
