Final answer:
A fracture with a broken bone but intact skin is called a closed fracture, differing from an open fracture where the bone pierces the skin.
Step-by-step explanation:
When a person has a fracture where the bone is broken but the skin remains intact, the correct term for this condition is a closed fracture. An open fracture, conversely, is when the broken bone breaks through the skin. It's important to know the different types of fractures, as they inform the method of treatment, such as closed or open reduction, and the healing process involving the formation and remodeling of Calli.
