Six cases of young children with thumb polydactyly in which the radial component was complicated by symphalangism are reported. Since the symphalangism was cartilaginous, plain X-rays showed an apparent joint space. However, its continuity was confirmed at surgery. Thumb polydactyly with symphalangism may be more common than previously expected.
