Study Notes

Types of Abrasions

  • Scratching Abrasion: Caused by sharp, pointed instruments scraping across the skin.
  • Sliding (Graze) Abrasion: Result of friction between skin and a hard, rough surface.

Other Types of Contusions

  • Impaction Abrasion: Occurs when a blunt object strikes the skin, causing a bruise without breaking it.
  • Pressure Abrasion: Results from prolonged pressure on the skin, leading to surface wear.
  • Fingernail Contusion: Small, rounded bruises resembling nail shapes.
  • Human Bite Contusion: Features two curved rows of bruising from a bite.
  • Rope Contusion: Creates a pattern similar to the rope when tied tightly against the skin.
  • Lacerated Contused Wound: Caused by sharp bone fragments penetrating through the skin due to a fracture.

Characteristics of Contused Wounds

  • Base is often irregular with tissue bridges present, indicating tissue connection despite the injury.

Cut Wounds (Incised Wounds)

  • Definition: An open wound produced by drawing the edge of a sharp instrument across tissue.
  • Characteristics: Base is regular with no tissue bridges, indicating a clean cut.

Indicators of Potential Self-Harm

  • Signs of distress such as failure in relationships or academic performance.
  • Physical evidence like a door being closed from both inside and outside, or disturbance of furniture.
  • Previous attempts of suicide without written explanation or, conversely, a letter may be found indicating suicidal intent.
