A depressed skull fracture is a type of fracture usually resulting from blunt force trauma, such as getting struck with a hammer, rock or getting kicked in the head. These types of fracturesâwhich occur in 11% of severe head injuriesâare comminuted fractures in which broken bones displace inward.
There are two types of fractures: open and closed. In an open fracture, the ends of the broken bone tear the skin. When the bone and skin are exposed, they are at risk of infection. This type of fracture is also called a compound fracture. In a closed fracture, the broken bone does not break the skin. This type of fracture is also called a simple fracture. But these fractures can be just as dangerous as open fractures.
