Mechanism of injury (MOI) is the means by which an injury occurs. [2] It is important because in the absence of an MoI there is no hazard. Common mechanisms of injury are "slips, trips and falls", for example: Hazard: Ex. a tool bag (in walkway) Mechanism of injury: Ex. trip (over tool bag) Injury = Bone fracture; Other common mechanisms of ...
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound.In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment.
Inflammation after injury occurs to protect against further damage and starts the healing process. Prolonged inflammation may cause multiple organ dysfunction syndrome or systemic inflammatory response syndrome. [21] Immediately after injury, the body increases production of glucose through gluconeogenesis and its consumption of fat via lipolysis.
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.
The pattern of injury, evaluation and treatment will vary with the mechanism of the injury. Blunt trauma causes injury via a shock effect; delivering energy over an area. Wounds are often not straight and unbroken skin may hide significant injury. Penetrating trauma follows the course of the injurious device.
Injury prevention is an effort to prevent or reduce the severity of bodily injuries caused by external mechanisms, such as accidents, before they occur. Injury prevention is a component of safety and public health , and its goal is to improve the health of the population by preventing injuries and hence improving quality of life .
Primary and secondary brain injury are ways to classify the injury processes that occur in brain injury. In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. [1] Secondary brain injury occurs gradually and may involve an array of cellular ...
A catastrophic injury is a severe injury to the spine, spinal cord, or brain. [1] It may also include skull or spinal fractures . [ 2 ] This is a subset of the definition for the legal term catastrophic injury , which is based on the definition used by the American Medical Association .
