What is the Rule of Nine?
The Rule of Nine is used to classify burn injuries in relation to the percentage of the total body surface area involved. The Rule of Nine is typically used in burn rehabilitation centers and involves dividing the body into multiples of nine to develop a percentage.
The head and neck are equal to nine percent of the body. The front and back are each equal to eighteen percent. Each arm is equal to nine percent, and each leg is equal to eighteen percent of the total body surface.
