What is polydactylism?

Answer:
Polydactylism, or having one or more extra fingers or toes, is probably the most common abnormality of development found at birth. Polydactylism is reported in about 2 per 1000 children. However, many of the simpler cases are taken care of in the nursery by the obstetrician or pediatrician and don't show up in these statistics.
