Abstract
Traumatic brain injuries are a major cause of morbidity and mortality in the community. This contributes significantly to the outcome in over half of trauma related deaths.
Traumatic brain injury is an insult to the brain resulting from an external mechanical force, possibly leading to permanent or temporary impairments of cognitive, physical, and psychosocial functions with an associated diminished or altered state of consciousness.
Traumatic brain injuries are classified into primary and secondary injuries. Primary injury occurs as an immediate result of the trauma itself. Secondary injury occurs later as a result of the primary injury.
Most head injuries are due to one of the two basic mechanisms contact or inertial loading. Contact injuries require that the head strikes an object, irrespective of whether the blow causes the head to move afterwards. Inertial injuries are often called acceleration injuries because they result from violent head motion, irrespective of whether the head moves because of a direct blow or not.
Contusions occur in a large percentage of traumatic brain injury. And most common in the frontal lobes because the The frontal lobes are particularly more susceptible to trauma. It refers most commonly to the injury that occurs after sudden deceleration impacts the brain with the bony prominences of the inner table in the anterior cranial fossa.
