Condition 101

What is the definition of Arachnodactyly?

Arachnodactyly is a condition in which the fingers are long, slender, and curved. They look like the legs of a spider (arachnid).

What are the alternative names for Arachnodactyly?

Dolichostenomelia; Spider fingers; Achromachia

CONSIDERATIONS

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 disorder.

What are the causes for Arachnodactyly?

Causes may include:

  • Homocystinuria
  • Marfan syndrome
  • Other rare genetic disorders

Note: Having long, slender fingers may be normal.

When should I contact a medical professional for Arachnodactyly?

Some children are born with arachnodactyly. It may become more evident over time. Talk to your health care provider if your child has long, slender fingers and you are concerned that an underlying condition may exist.

WHAT TO EXPECT AT YOUR OFFICE VISIT

The provider will perform a physical exam. You will be asked questions about the medical history. This includes:

  • When did you first notice the fingers being shaped like this?
  • Is there any family history of early death? Is there any family history of known hereditary disorders?
  • What other symptoms are present? Have you noticed any other unusual things?

Diagnostic tests are most often not necessary unless a hereditary disorder is suspected.
