What is Polydactyly?

  • A small raised bump or skin that looks like an extra finger or toe that isn't formed all the way.

Surgery is usually required to remove the extra finger or toe in a way to the level of the split, (bone or joint). Surgery is required as early has 6 months of age. Secondary surgery is required if polydactyly is developed at an older age.

Polydactyly is passed on by one parent if they have the disorder. Caused by a dominant allele of a gene.
