MECHANISMS OF INJURY INTRODUCTION Trauma starts with the transfer of energy to the body from an outside force. The transfer of kinetic energy may be blunt or sharp in nature. In addition to blunt and sharp mechanisms, there is the situation of thermal energy in the form of heat, cold, or chemical agent, which generates the heat or cold. With the
