Trauma surgery is a type of surgery that doctors do to help when you are hurt in an accident or fall. It is usually done in an emergency situation, so the doctors have to work really fast to make sure your body can heal and stay healthy. They might have to put in stitches to close cuts and replace any broken bones. They may also have to put you on medicines to help your body heal, like antibiotics to fight infections. In extreme situations, doctors might even have to remove parts of your body, like a spleen, if it has been hurt too badly.
