Physiologic genu valgum
Pronunciation: JEE-noo VAL-gum
Normal developmental knee alignment variation in children, typically resolving by age 6-8 years.
Full Definition
Physiologic genu valgum refers to the normal developmental phase where children exhibit knee valgus (knock-knee) alignment, typically appearing between ages 2-4 years and spontaneously correcting by ages 6-8 years. This represents part of the normal progression from infantile genu varum (bow legs) through neutral alignment. The condition is bilateral, symmetric, and painless, with the intercondylar distance usually less than 8cm. Understanding this normal variant is crucial for pediatric trauma specialists to differentiate from pathologic valgus deformities that may require intervention or indicate underlying conditions such as lateral growth arrest or metabolic bone disease.
Usage
Usage note: Important to distinguish from pathologic conditions in pediatric assessments.
