The "rule of nines" is a method used to estimate the total body surface area (TBSA) affected by burns in an adult patient. It divides the body into sections, each representing approximately 9% (or multiples thereof) of the TBSA.<br /><br />Here are the percentages for each section according to the rule of nines:<br /><br />- **Head and neck:** 9%<br />- **Posterior trunk:** 18%<br />- **Anterior trunk:** 18%<br />- **Each upper extremity:** 9% (4.5% for the front and 4.5% for the back)<br />- **Each lower extremity:** 18% (9% for the front and 9% for the back)<br />- **Groin area:** 1%<br /><br />So, filling in the blanks:<br /><br />- Head and neck: 9%<br />- Posterior trunk: 18%<br />- Anterior trunk: 18%<br />- Each upper extremity: 9%<br />- Each lower extremity: 18%<br />- Groin area: 1%
