Footprint analysis during the growth period

Area of Science:

• Pediatric orthopedics
• Human growth and development

Background:

• Understanding typical foot development is crucial for identifying potential abnormalities.
• The pediatric foot undergoes significant changes from birth through adolescence.

Purpose of the Study:

• To document the developmental changes in foot length and medial longitudinal arch in healthy children.
• To establish normative data for foot growth in a pediatric population.

Main Methods:

• Static footprints were collected from 672 healthy Caucasian children aged 0-15 years.
• Foot length was measured, and the medial longitudinal arch was assessed.
• Data were analyzed to determine growth patterns and arch development stages.

Main Results:

• Foot growth was most rapid before age 3, then slowed to a consistent rate until age 12.
• Girls' feet ceased growth at 12 years, while boys' feet continued growing.
• A higher prevalence of flat feet was noted from birth to 2 years, with significant arch development between 2 and 6 years.

Conclusions:

• Pediatric foot growth exhibits distinct phases, with accelerated growth in early childhood and sex-specific differences emerging around puberty.
• The development of the medial longitudinal arch is a dynamic process during early childhood.
• These findings provide valuable reference data for pediatric foot assessment.
