Arachnodactyly - Overview

Definition of Arachnodactyly:

Arachnodactyly is a physical condition in which the fingers are long, slender, and curved, resembling a spider's legs.

Considerations:

Long, slender fingers can be normal and not associated with any medical problems. In some cases, however, the tendency to develop spider fingers can indicate an underlying disease.

Common Causes:

• Homocystinuria
• Marfan's syndrome
• Other rare genetic disorders

Note: Having long, slender fingers may be normal.
