Traumatic brain injury results from the application of mechanical input to the head. The initial damage occurring at the very injury moment is considered the primary or mechanical injury. Secondary or non-mechanical injury results from complications which can produce additional and delayed damage. Two mechanical phenomena constitute the most common causes of primary brain injury: contact effect and inertial load. The only way to avoid the primary injury is to promote a culture of prevention and recognition of risk factors in child abuse. This article makes reviews mechanisms of primary head injury.
