What is the TBSA percentage for an adult leg?

The Total Body Surface Area (TBSA) percentage for an adult leg is considered to be 18%. This figure is derived from the "Rule of Nines," which is a method used to estimate the percentage of the body affected by burns. According to this rule, each leg constitutes approximately 18% of the total body surface area in adults.

The breakdown is as follows: each entire leg (including the front, back, and both skin surfaces) is allocated 9% for the front and 9% for the back, totaling 18% for one leg. This is particularly valuable when assessing the severity of burns and determining treatment protocols, such as fluid resuscitation and potential transfer to specialized burn units. Understanding these percentages is crucial for first responders and healthcare providers in order to manage burn injuries effectively.
