Unilateral duplication of the great toe with anterolateral tibial bowing.

A syndrome consisting of unilateral duplication of the great toe in association with anterolateral bowing of the tibia is described. Patients with this syndrome have significant pedal difficulties after surgical management, but the tibial bowing spontaneously resolves without treatment. Tibial shortening is noted relative to the fibula. Associated clinodactyly and dysharmonic maturation of carpals and metacarpals are also seen. Current data are most consistent with a developmental rather than a genetic etiology.
