Bunions in Children and Teens (Juvenile Hallux Valgus)
Juvenile hallux valgus is a bunion deformity (big toe angling toward second toe with bony bump on inside of foot) developing in children and adolescents (typically ages 10-15), often with strong family history and associated with flexible flatfeet or ligament laxity—causing pain, difficulty fitting shoes, and cosmetic concern. Unlike adult bunions which are progressive and degenerative, juvenile bunions often have underlying structural factors (metatarsus primus varus—inward angling of first metatarsal bone). Non-surgical management (wide shoes, avoiding heels, padding) is preferred until skeletal maturity due to high recurrence rates (30-50%) with early surgery. Surgery considered for persistent symptoms after skeletal maturity (age 14-16+ in girls, 16-18+ in boys) has better success but still higher recurrence than adult bunion surgery.

🔬What Causes It?
- Genetic predisposition (runs in families—60-70% have family history)
- Structural foot abnormalities (metatarsus primus varus—first metatarsal angled inward)
- Flexible flatfeet or excessive foot pronation (arch collapses when walking)
- Generalized ligament laxity or hypermobility syndromes
- Tight heel cord (Achilles tendon) increasing forefoot pressure
⚠️Risk Factors
You may be at higher risk if:
- Family history of bunions (especially mother with bunions)
- Female gender (3-4 times more common than males)
- Ballet dancers, gymnasts (activities requiring foot flexibility)
- Flexible flatfeet or excessive pronation
- Conditions causing ligament laxity (Ehlers-Danlos, Marfan syndrome)
🛡️Prevention
- ✓Proper footwear (wide-toe-box shoes, avoiding narrow/pointed shoes and heels)
- ✓Early treatment of flexible flatfeet if present
- ✓Heel cord stretching if tight
- ✓Genetic counseling if strong family history
- ✓Annual monitoring if bunion developing
