These two conditions are the most common hand and foot conditions seen by pediatric plastic surgeons. While some can be treated non surgically, most require surgical treatment.

Polydactyly ranges from an extra piece of soft tissue (skin) that has no bone inside to a complete duplication of a finger or toe.

There are different levels of duplication depending which bone in the thumb is split. The thumb may have 3 bones instead of two, this is called a triphalangeal thumb.


Duplication of index, middle or ring finger (central duplication)
