Q71.31 Congenital absence of right hand and finger

Name of the Condition

• Congenital absence of right hand and finger

Summary

Congenital absence of the right hand and finger is a limb reduction defect where the right hand and its digits are absent at birth. This condition is part of a broader group of congenital upper limb anomalies and can impact functional abilities, though the presence of the forearm and arm may allow for adaptive use.

Causes

The exact causes are often unknown but may involve genetic factors, chromosomal abnormalities, or environmental influences during pregnancy. Disruptions to normal fetal limb development, such as vascular issues or teratogenic exposures, are also implicated.

Risk Factors

• Genetic predispositions or family history of limb defects.
• Maternal exposure to certain medications, chemicals, or infections during pregnancy.
• Maternal conditions like diabetes or autoimmune disorders.
• Advanced maternal age.

Symptoms

• Visible absence of the right hand and fingers at birth.
• Malformation of bones, muscles, or soft tissues in the affected area.
• Potential limitations in movement, strength, or dexterity of the limb.

Diagnosis

Diagnosis is typically made at birth through physical examination. Prenatal ultrasounds may detect limb abnormalities before delivery, though complete absence of the hand and fingers can be challenging to identify prenatally.

Treatment Options

• Prosthetic fitting to enhance functionality and independence.
• Occupational therapy to develop adaptive skills using remaining limbs.
• Surgical interventions for functional or cosmetic improvements, if applicable.

Prognosis and Follow-Up

Prognosis depends on the severity of the defect and associated anomalies. Early intervention, including therapy and prosthetics, can improve functional outcomes. Regular follow-up with specialists is recommended to monitor development and address any emerging needs.

Complications

• Functional limitations affecting daily activities.
• Potential psychological or social challenges related to limb difference.
• Increased risk of secondary musculoskeletal issues due to altered biomechanics.

Lifestyle & Prevention

• Early occupational therapy to support adaptive skill development.
• Use of assistive devices to aid in daily tasks.
• Genetic counseling for families with a history of limb defects.

When to Seek Professional Help

Seek medical evaluation if a newborn shows signs of limb absence or malformation. Prompt assessment by a pediatrician or specialist is important for diagnosis and early intervention.

Tips for Medical Coders

Document the specific absence of the right hand and fingers, including any associated anomalies. Ensure the code Q71.31 is used when the right hand and fingers are congenitally absent, with clear clinical documentation supporting the diagnosis.
