Skull fractures. Your skull can fracture during an injury to your head. If this happens, you'll usually have a CT scan to determine the extent of the injury. There are different types of skull fractures, including: 1  simple (or closed) fracture â where the skin hasn't broken and the surrounding tissue isn't damaged. 2  compound (or open) fracture â where the skin has broken and the surrounding tissue may be damaged.
A blow to the head can cause a more serious initial injury to the brain. A contusion is a bruise of the brain tissue involving bleeding and swelling in the brain. A skull fracture occurs when the bone of the skull breaks. A skull fracture by itself may not necessarily be a serious injury.
