Arachnodactyly is a condition in which the fingers are long, slender, and curved. They look like a spider's legs.
Long, slender fingers can be normal and not associated with any medical problems. In some cases, however, "spider fingers" can be a sign of an underlying disease.
Note: Having long, slender fingers may be normal.
Some children are born with arachnodactyly, although it may develop over time. Consult with your health care provider during a routine examination if your child has long, slender fingers and you are concerned that an underlying condition may exist.
The health care provider will perform a physical exam and ask questions about the person's medical history, including:
