Definition of Basilar fracture

Basilar fracture: A break in bone at the base of the skull. About a half of basilar fractures are caused by bicycle or motor vehicle accidents, about a quarter by falls, and a tenth by recreational activities, particularly by diving accidents. The balance are due to other causes. No matter what cause, the risk of death with a basilar fracture is appreciable.

The term basilar means located at or near the base of a structure, especially the skull.
