What is Syndactyly?
Syndactyly, one of the most common congenital hand anomalies, is an abnormal connection of fingers or toes to one another—the digits are “webbed,” and have failed to separate normally during development. It most commonly involves the middle and ring fingers. In about 50% of cases, both hands are involved. Syndactyly may occur alone, or with other anomalies as part of a syndrome.

Are there different forms and different levels of severity with syndactyly?
Yes. The classifications of syndactyly correspond to the conditions different types and degrees of complexity. Syndactyly can be classified in the following ways:
- Incomplete: the webbing or joining doesnt extend all the way to the fingertips.
- Complete: the webbing or joining extends all the way to the fingertips.
- Simple: the fingers are joined only by soft tissue.
- Complex: the fingers are joined by bone or bony cartilage, as well as soft tissue, in a side-by-side fashion.
- Complicated: the fingers are joined by bone or bony cartilage, as well as soft tissue, in a fashion other than side-by-side such as with abnormally shaped, extra or missing bones.
