Arachnodactyly is a physical condition in which the fingers are long, slender, and curved, resembling a spider's legs.
Dolichostenomelia; Spider fingers; Achromacria
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 patient's medical history, including:
- Time pattern
- When did you first notice the fingers being shaped like this?
- Family history
- Is there any family history of early death?
- Is there any family history of known hereditary disorders?
- What other symptoms are also present?
- Have you noticed any other unusual things?
Diagnostic tests are usually not necessary unless a hereditary disorder is suspected.
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.
