According to the Rule of Nines, what percentage of TBSA does one leg represent in adults?

In adult patients, one leg accounts for 18% of the total body surface area (TBSA) when using the Rule of Nines for burn assessment. This system divides the body into sections, each representing approximately 9% or multiples of 9% of TBSA. Each entire leg is considered to consist of 18%, which includes 9% for the front and 9% for the back of the leg.

Understanding the Rule of Nines is crucial for effectively assessing burn severity and planning treatment, as it provides a quick method for estimating the extent of burns. The misallocation of TBSA percentage can lead to inappropriate fluid resuscitation and other interventions, making it essential to remember that an entire leg is designated as 18%, not 9%, 15%, or 7%.
