What is Arachnodactyly?

Description of the disease

Arachnodactyly is a congenital or acquired condition characterized by elongation and thinning of the fingers and toes. In people with arachnodactyly, the fingers resemble spider legs, which explains the name of the condition, derived from the words arachno (spider) and dactyly (fingers).

Classification

• Congenital arachnodactyly;
• Acquired arachnodactyly.

Symptoms

• Elongated and thin fingers;
• Altered nail shape;
• Curved or deformed joints.

Causes

The causes of congenital arachnodactyly are not fully understood, but it is likely a genetic condition. Acquired arachnodactyly may be caused by rheumatoid arthritis, injuries, infections, and other factors.

Diagnosis

Diagnosis of arachnodactyly involves a visual examination of the patient, X-rays, and, if necessary, genetic tests to identify the congenital form of the condition.

Treatment

In the case of congenital arachnodactyly, treatment may include surgical correction to improve the functionality of the fingers. Acquired arachnodactyly is treated by addressing the underlying condition that caused the deformation.

Prevention

Since congenital arachnodactyly is related to genetics, preventing this condition is often not possible. However, preventing injuries and infections can help avoid acquired arachnodactyly.

Doctor

To diagnose and treat arachnodactyly, it is advisable to consult a surgeon or orthopedist.
