What is the Rule of Nines for burn assessment?

In adults: head and neck 9%, each arm 9%, anterior trunk 18%, posterior trunk 18%, each leg 18%, genitalia 1%. Partial thickness and full thickness burns are counted; superficial/epidermal burns are excluded.

Why is the Lund-Browder chart preferred in children?

Children have proportionally larger heads and smaller legs than adults. The Lund-Browder chart adjusts these proportions by age, giving more accurate TBSA estimates than the Rule of Nines in pediatric patients.
