Major trauma is a severe traumatic injury that has the potential to cause disability or death. Serious traumatic injury most often occurs as a result of traffic collisions. [11] Traumatic injury is the leading cause of death in people under the age of 45. [12] Blunt trauma injuries are caused by the forceful impact of an external object.
contralateral head injury; The mechanism of injury is an initial impact causing injury to the femur on one side (bumper injury) and the torso on the same side (fender or hood), following which the child is thrown, striking the head on the ground or another object and sustaining injury to the opposite side of the head.

Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects , by heat or cold, or by venoms and biotoxins .
Intentional injury is a common cause of traumas. [13] Penetrating trauma is caused when a foreign body such as a bullet or a knife enters the body tissue, creating an open wound. In the United States, most deaths caused by penetrating trauma occur in urban areas and 80% of these deaths are caused by firearms. [14]
Diffuse injury has more microscopic injury than macroscopic injury and is difficult to detect with CT and MRI, but its presence can be inferred when small bleeds are visible in the corpus callosum or the cerebral cortex. [34] MRI is more useful than CT for detecting characteristics of diffuse axonal injury in the subacute and chronic time ...
External Cause of Injury Codes (E codes) are ICD-9-CM codes or ICD-10 codes that are used to define the mechanism of death or injury, along with the place of occurrence of the event. E codes are assigned on death certificates based on the manner of death. ICD-10 codes in the range V01–X59 refer to unintentional injuries.
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. [10] Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology. [11]
Axonotmesis mainly follows a stretch injury. These stretch injuries can either dislocate joints or fracture a limb, due to which peripheral nerves are severed. If the sharp pain from the exposed axon of the nerve is not observed, one can identify a nerve injury from abnormal sensations in their limb.
