Q70.03 Fused fingers, bilateral

Name of the Condition

• Fused Fingers, Bilateral
• Syndactyly, Bilateral

Summary

Fused fingers, medically known as syndactyly, is a congenital condition where two or more fingers are joined together. This entry specifically addresses bilateral involvement, meaning both hands are affected. The fusion can involve soft tissues, bones, or both, and may range from a simple webbing of skin to a complete fusion of the digits. The condition is typically present at birth and can impact finger function and appearance.

Causes

Fused fingers are primarily caused by genetic factors. The condition results from the failure of the fingers to separate during fetal development. It can occur as an isolated anomaly or as part of a genetic syndrome, such as Apert syndrome or Poland syndrome.

Risk Factors

• Family history of syndactyly or related genetic conditions.
• Occurrence in certain genetic syndromes which may include fused fingers as a symptom.

Symptoms

• Fusion of skin and/or bones between two or more fingers on both hands.
• Limited finger movement and dexterity in the affected hands.
• Potential difficulty in performing tasks requiring fine motor skills.

Diagnosis

Diagnosis is made through a physical examination by a healthcare provider. Imaging tests, such as X-rays, may be used to determine the extent of fusion involving bones.

Treatment Options

• Surgical separation: Typically recommended to improve function and appearance.
  • The surgery is usually performed before school age to optimize outcomes.

Prognosis and Follow-Up

Prognosis is generally good with appropriate surgical intervention. Follow-up care may include physical therapy to improve finger mobility and function. Regular monitoring by a healthcare provider is recommended to address any complications or functional concerns.

Complications

• Reduced finger mobility and dexterity.
• Potential functional impairment in daily activities.
• Cosmetic concerns related to finger appearance.

Lifestyle & Prevention

No specific lifestyle changes can prevent congenital syndactyly. Genetic counseling may be beneficial for families with a history of the condition.

When to Seek Professional Help

Consult a healthcare provider if you notice fused fingers in a newborn or if the condition affects hand function or causes discomfort.

Tips for Medical Coders

Document the bilateral nature of the fused fingers and any associated syndromes or complications. Ensure the diagnosis is clearly supported by clinical findings and imaging results when available.
