Document Summary
Injuries midterm 2: orthopaedic injuries (lecture 7 16) injurie. Concussion: a complex pathophysiological process affecting the brain, induced by traumatic biochemical forces. Brain rotates stretches or tears structures/vessels as it shears on itself. A direct blow to the head, face or neck. Elsewhere on the boy with an impulsive force transmitted to the head. There is no agreed-on biomechanical threshold for injury. Force does not factor in on symptom severity - you do not need to hit your head hard. Concussion impact - not always the hardest hit. The inherent material design of helmets are ideal for preventing high impact forces associated with catastrophic head injuries (skull fractures) but less ideal for reducing the impact/rotational forces to which concussions are typically related. There is no strong scientific evidence of an association between mouth-guard use and reduced concussion risk. Concussions are not getting worse we are just getting smarter. 35 concussion severity scales have been published none have been scientifically validated.
