Which body part in burn assessments accounts for 9% each according to the Rule of 9’s?

In burn assessments, the "Rule of 9’s" is a method used to estimate the total body surface area (TBSA) affected by burns. According to this rule, each upper extremity accounts for 9% of the total body surface area. This calculation is crucial for determining the severity of burns and guiding treatment decisions.

In this system, other body sections such as lower extremities are assigned a total of 18% each, the anterior and posterior torso accounts for 18% each, and the head and neck collectively account for 9%. Understanding these classifications helps healthcare providers quickly assess the extent of burns and prioritize care. Therefore, recognizing that each upper extremity is assigned a consistent percentage of 9% is essential for accurate burn assessments in both pre-hospital and hospital settings.
