Traumatic injuries are classified into blunt and penetrating injuries. Penetrating injuries are caused when an object such as a knife or bullet crushes and tears the tissues that it traverses. The energy transfer from the penetrating object to the tissues determines the degree of injury, and the wounding tract determines the pattern of injury. Blunt trauma produces injury by transferring energy through acceleration forces (+ and -) to the victim (usually from motor vehicles or falls). The pattern and severity of injury are determined by the magnitude and orientation of the acceleration change to the victim's anatomy.
创伤性损伤分为钝器伤和穿透伤。当诸如刀或子弹之类的物体挤压并撕裂其所穿过的组织时，就会造成穿透伤。从穿透物体到组织的能量传递决定了损伤程度，而伤口通道决定了损伤模式。钝器伤是通过加速力（正向和负向）将能量传递给受害者（通常来自机动车辆或跌倒）而造成损伤。损伤的模式和严重程度取决于受害者解剖结构上加速度变化的大小和方向。
