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.
