Flashcards in Forensic Aspects of Trauma Deck (7)
How do you classify injury?
Appearance or method of causation - abrasion, contusion, laceration, incised wounds, gunshot wounds, burns
Manner of causation - suicidal, accidental, homocidal
Nature of injury - blunt force, sharp force, explosive
What are contusions?
Burst blood vessels in the skin
What are abrasions?
Scraping of the skin surface
What are lacerations?
Tear / split of the skin due to crushing
What are factors affecting prominence of bruises?
- Skin pigmentation
- Depth and location – occur more readily over loose skin – eyebrow, scrotum
- Fat - ↑ subcut fat = bruise more easily
- Age - Children – skin loose and delicate
- Elderly - blood vessels of skin poorly supported
- Resilient areas – buttocks, abdomen – bruise less easily with given impact than areas with underlying bone which acts as an anvil with skin between bone and inflicting object
- Coagulative disorders – thrombocytopenia, Von Willebrand’s disease, haemophilia, liver disease (alcoholics), bone marrow disease
What is the difference between a stab wound and an incised wound?
Incised wound = superficial sharp force injury caused by slashing motion, longer on the skin surface than it is deep
Stab wound = Penetrating injury resulting from thrusting motion, wound depth is greater than the length on the surface
