Blunt trauma. Blunt trauma, also known as blunt force trauma or non-penetrating trauma, describes a physical trauma due to a forceful impact without penetration of the body's surface. Blunt trauma stands in contrast with penetrating trauma, which occurs when an object pierces the skin, enters body tissue, and creates an open wound.
Concussion is an injury to the brain caused by being hit on the head, as often happens in motor vehicle collisions, fights or contact sports such as football. It is the most common form of traumatic brain injury. Related terms include mild brain injury, mild traumatic brain injury (MTBI), mild head injury (MHI), and minor head trauma.
Physical trauma. When people experience physical trauma, such as a head injury in a car accident, it can result in effects on their memory. The most common form of memory disturbance in cases of severe injuries or perceived physical distress due to a traumatic event is post-traumatic stress disorder, discussed in depth later in the article.
Trauma; multiple traumatic injuries can lead to chronic traumatic encephalopathy. A coup-contrecoup injury occurs when the force impacting the head is not only strong enough to cause a contusion at the site of impact, but also able to move the brain and cause it to displace rapidly into the opposite side of the skull, causing an additional ...
Penetrating head injury. A penetrating head injury, or open head injury, is a head injury in which the dura mater, the outer layer of the meninges, is breached. [1] Penetrating injury can be caused by high- velocity projectiles or objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain.

Head and brain injuries are commonly associated with facial trauma, particularly that of the upper face; brain injury occurs in 15–48% of people with maxillofacial trauma. Coexisting injuries can affect treatment of facial trauma; for example they may be emergent and need to be treated before facial injuries.
