Q72.11 Congenital absence of right thigh and lower leg with foot present

Name of the Condition

• Congenital absence of right thigh and lower leg with foot present

Summary

Congenital absence of the right thigh and lower leg with the foot present is a rare limb reduction defect where the right thigh and lower leg are missing, but the foot remains attached. This condition affects mobility and may require medical evaluation and adaptive interventions.

Causes

The exact cause is often unknown but may involve genetic factors, disruptions in fetal limb development, or environmental influences during pregnancy. Vascular issues or amniotic band syndrome can also contribute to limb reduction.

Risk Factors

• Family history of limb abnormalities.
• Maternal exposure to certain medications, chemicals, or infections during pregnancy.
• Genetic syndromes or chromosomal abnormalities.

Symptoms

• Visible absence of the right thigh and lower leg at birth, with the foot present.
• Potential functional limitations affecting movement or balance.
• Possible associated anomalies in other body systems.

Diagnosis

Physical examination immediately after birth to assess limb structure. Prenatal ultrasound may detect limb differences before delivery. Imaging studies (e.g., X-rays) or genetic testing to evaluate severity and rule out syndromes.

Treatment Options

• Prosthetic fitting to improve mobility and function.
• Orthotic devices to support limb alignment.
• Physical therapy to enhance strength and coordination.
• Surgical interventions may be considered for functional or cosmetic reasons.

Prognosis and Follow-Up

Prognosis depends on the severity of the defect and associated conditions. Early intervention with prosthetics, therapy, and monitoring can improve quality of life. Regular follow-up with specialists is recommended to address developmental needs.

Complications

• Mobility challenges and potential gait abnormalities.
• Increased risk of secondary musculoskeletal issues.
• Possible psychological or social impacts related to physical differences.

Lifestyle & Prevention

• Engage in physical therapy to maintain strength and mobility.
• Use adaptive equipment as recommended by healthcare providers.
• Monitor for associated health issues and address them promptly.

When to Seek Professional Help

Seek medical attention if there are concerns about limb development during pregnancy or if the newborn shows signs of limb absence. Early evaluation by a pediatrician or specialist is important for diagnosis and intervention.

Tips for Medical Coders

Document the specific absence of the right thigh and lower leg with the foot present. Ensure clinical notes support the diagnosis and specify the affected limb. Follow coding guidelines for congenital limb reduction defects, and verify documentation aligns with the code description.
