| How accurate can injuries be predicted by knowing the MOI |
|
Definition
|
|
Term
| Factors involved in MOI for blunt forced trauma include |
|
Definition
-speed
-angle of impact
-use of restraints
-airbag deployment
-condition of steering wheel and -windscreen
-amount of intrusion
-person ejected from vehicle
-any deceased at scene |
|
|
Term
| Frontal impact potential/expected injuries: |
|
Definition
-Head: contusions, lacerations, skull #'s, cerebral haemorrhage/contusion
-Chest: # ribs, # sternum, flail chest, pulmonary/myocardial contusion
-abdomen: ruptured hollow organs (bladder, stomach), ruptured solid organs (liver, spleen).
-Lower limb: # patella, # midshaft femur, #/posterior dislocation of femoral head |
|
|
Term
| rear impact potential/expected injuries |
|
Definition
| -person goes forwards then backwards- hyperextension of neck |
|
|
Term
| side impact potential/expected injuries |
|
Definition
-car appears to move from under person
-person moves toward point of impact
-chest and hip hit door
-C-spine injury
-Head injury |
|
|
Term
| vehicle rollover potential/expected injuries |
|
Definition
-multiple impacts each time the vehicle roles
-injuries unpredictable
-assume presence of severe injury
-profound increase in fatality rates when person is ejected in a rollover |
|
|
Term
| Ejection potential/expected injuries |
|
Definition
initial injuries from point of impact
spinal/head injuries
probability of death increases 6 fold |
|
|
Term
| Motorcyclists potential/expected injuries |
|
Definition
-Headon: rider goes over handlebars. Head and neck injuries. Direct contact with handlebars can cause pelvic, chest and abdo injuries
-Bike collapses on rider--> crushed leg fracture
-Head, neck and extremity injuries occur frequently due to lack of protective equipment- head injuries decrease by 300% if rider wears a helmet. |

Term
|
Definition
| Damage to tissue when structures in the path of the instrument are punctured. |
|
|
Term
|
Definition
Damage can't be determined by location of entrance/exit wounds:
-missiles tumble
-secondary missiles from bone fragments
-damage from blast effect and cavitation |
