Q72.32 Congenital absence of left foot and toe(s)

Name of the Condition

• Congenital Absence of Left Foot and Toe(s)
• Medical term: Terminal Transverse Limb Deficiency (Left Foot)

Summary

Congenital absence of the left foot and toe(s) is a birth defect where a newborn is missing all or part of the foot and toes on the left side. This condition impacts mobility and may require medical intervention and adaptive solutions from a young age.

Causes

The exact cause is often unknown. It may be related to genetic factors or environmental influences during pregnancy. Possible disruptions in blood supply or amniotic band syndrome during fetal development can also contribute.

Risk Factors

• Family history of limb abnormalities.
• Maternal exposure to certain chemicals or medications during pregnancy.
• In some cases, the condition might occur sporadically without apparent risk factors.

Symptoms

• Absence of visible foot and toes at birth on the left side.
• Potential impact on movement and balance.
• Developmental delays in mobility milestones in early childhood due to physical limitations.

Diagnosis

Physical examination immediately after birth. Prenatal ultrasound might identify limb differences before birth. Genetic testing may be offered to rule out associated syndromes.

Treatment Options

• Prosthetic fitting to aid mobility and function.
• Physical therapy to support strength and balance.
• Surgical interventions may be considered for specific cases.

Prognosis and Follow-Up

Prognosis depends on the severity of the deficiency and the effectiveness of interventions. Regular follow-up with orthopedic specialists and physical therapists is typically recommended to monitor development and adjust treatments as needed.

Complications

• Challenges with mobility and balance.
• Potential for secondary musculoskeletal issues due to altered gait.
• Emotional or psychological impacts related to physical differences.

Lifestyle & Prevention

• Early use of adaptive devices to support mobility.
• Physical therapy to maintain strength and flexibility.
• Counseling or support groups for coping with physical and emotional challenges.

When to Seek Professional Help

Seek immediate medical evaluation if a newborn shows signs of missing or malformed limbs. Ongoing care from specialists is important for managing mobility and addressing developmental needs.

Tips for Medical Coders

Document the specific laterality (left foot) and whether the absence involves partial or complete foot and toe structures. Ensure clinical notes support the diagnosis and specify any associated anomalies or interventions for accurate coding.
