Unique case of polydactyly and a new classification system.
Polydactyly of the hands or feet is a common birth deformity. We recently encountered a female infant with a case of a crossed type 1 polydactyly with a mixed polydactyly of the feet. A mixed and crossed polydactyly is a rare finding with only one other reported case. This is the first report of crossed and mixed polydactyly of the feet presenting with 7 complete toes on each foot without syndactyly. In addition to a discussion of the treatment, this case has lead us to propose a more complete and less confusing classification system.
