Arachnodactyly is a condition in which the fingers are long, slender, and curved. They look like a spider's legs.
Dolichostenomelia; Spider fingers; Achromacria
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.
Call your health care provider if
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.
What to expect at your health care provider's office
The health care provider will perform a physical exam and ask questions about the patient's medical history, including:
- Time pattern
- Family history
Diagnostic tests are usually not necessary unless a hereditary disorder is suspected.
