Definition

An inclusive term to explore and describe the mechanical and physical factors that result in traumatic brain injury.

Current Knowledge

Biomechanical injuries typically occur without the direct impact of an outside object on the skull or brain, but rather in the context of acceleration-deceleration injuries or blast injuries. High-speed situations such as motor vehicle accidents and sports provide mediums for these inertia-based injuries. The structure of the skull includes sinuses and bony protective regions. Underlying brain tissue is held in suspension underneath the skull not only by the meninges, but also by a cushion of cerebral spinal fluid. Different inertial forces such as linear acceleration, rotation of the head, or massive vibration or air pressure changes in the environment can result in a wide range of potential damage to these underlying substances. These disruptions may include skull fracture, linear acceleration injury, rotational injury, and the effects of...
