Blunt trauma is physical trauma to a body part, either by impact, injury or physical attack. The latter is often referred to as blunt force trauma, though it can also result from high-velocity impact. Blunt trauma is the initial trauma, from which develops more specific types such as contusions, abrasions, lacerations, and/or bone fractures. Blunt trauma is contrasted with penetrating trauma, in which an object such as a projectile or knife enters the body, though either can prove fatal
