Nerve compression is a result of poor posture, prolonged computer use is an example of repetitive strain injury which affects the musculoskeletal system. [ 16 ] [ 2 ] Whiplash injury , whereby the force causes strain to the capsule and ligaments of the apophyseal joints of the cervical spine . [ 7 ]
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.
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 ...
Pathology is the medical discipline that describes conditions typically observed during a disease state, whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism. Pathology describes the abnormal or undesired condition (symptoms of a disease), whereas pathophysiology seeks to explain ...
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

Examples of these indications include penetrating neck trauma, expanding neck hematoma, and being unconscious. In general, the method of intubation used is rapid sequence intubation followed by ventilation, though intubating in shock due to bleeding can lead to arrest, and should be done after some resuscitation whenever possible.
Damage to the meniscus due to rotational forces directed to a flexed knee (as may occur with twisting sports) is the usual underlying mechanism of injury. A valgus force applied to a flexed knee with the foot planted and the femur rotated internally can result in a medial meniscus tear. A varus force applied to the flexed knee when the foot is ...
Closed head injury (coup contrecoup) can damage more than the impact sites on the brain, as axon bundles may be torn or twisted, blood vessels may rupture, and elevated intracranial pressure can distort the walls of the ventricles. [7] [10] [11] Diffuse axonal injury is a key pathology in concussive brain injury. [5] The visual system may be ...
