Q70.11 Webbed fingers, right hand

Name of the Condition

• Webbed fingers, right hand

Summary

Webbed fingers, right hand is a congenital condition where two or more fingers on the right hand are joined by skin or soft tissue. This condition, also known as syndactyly, is present at birth and may involve partial or complete fusion of the digits. The extent of fusion can range from a simple webbing of skin to a more complex connection involving bones or nails.

Causes

Webbed fingers result from genetic factors that disrupt normal finger separation during fetal development. The condition occurs when the fingers fail to fully separate, a process that typically completes by the eighth week of gestation. It may 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.
• Association with genetic syndromes that include limb malformations.

Symptoms

• Fusion of skin, nails, or bones between adjacent fingers on the right hand.
• Reduced range of motion and dexterity in the affected digits.
• Potential functional impairment, particularly in tasks requiring fine motor skills.

Diagnosis

Diagnosis is made through physical examination to assess the extent of fusion. Imaging studies, such as X-rays, may be used to evaluate bone involvement and guide treatment planning.

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

With appropriate surgical intervention, most individuals achieve improved function and appearance. Follow-up care may include physical therapy to enhance mobility and regular monitoring for any recurrence or complications.

Complications

• Limited hand function if untreated.
• Potential for social or psychological impact due to appearance.
• Risk of complications from surgery, such as infection or scarring.

Lifestyle & Prevention

No specific preventive measures exist, as the condition is congenital. Early intervention and support can help manage functional and cosmetic concerns.

When to Seek Professional Help

Consult a healthcare provider if you notice webbing or fusion of fingers at birth, or if the condition affects daily activities or causes concern.

Tips for Medical Coders

Document the specific hand (right) and extent of fusion (soft tissue, bone, or both) to ensure accurate coding. Include details about associated syndromes or family history if applicable.
