A skull fracture is any break in the cranial bone, also known as the skull. There are many types of skull fractures, but only one major cause: an impact or a blow to the head that’s strong enough to break the bone. An injury to the brain can also accompany the fracture, but that’s not always the case. Treatment depends on the severity of the fracture. Pain medication may be the only treatment necessary in mild fractures, while neurosurgery may be required for more serious injuries. The type of skull fracture depends on the force of the blow, the location of the impact on the skull, and the shape of the object making impact with the head.
