Open Wounds:-
These are wounds that present as raw open areas and are of various types:
- Cut wounds or incision wounds are a result of cuts by a clean, sharp-edged object such as a knife or a glass cutting into the skin.
- Lacerations are irregular tear-like wounds caused by blunt trauma.
- Abrasions are superficial wounds in which the topmost layer of the skin is scraped off. They are often caused by sliding or falling on a rough surface.
- Puncture wounds are caused by an object puncturing the skin, such as a nail or needle. t Penetration wounds are caused by an object, such as a knife, entering and coming out from the skin.
- Missile wounds, also called velocity wounds, are caused by an object entering the body at a high speed, typically a bullet.
- Avulsions occur when an entire structure or part of it is forcibly pulled away; such as the loss of a permanent tooth or an ear lobe.
Closed Wounds:-
Closed wounds are wounds beneath the skin where the skin surface remains intact despite the injury. They are of few types but are just as dangerous as open wounds. The types of closed wounds are:
- Contusions, more commonly known as bruises, are caused by blunt force trauma that damages tissues under the skin.
- Hematoma, also called a blood tumor, is caused by damage to a blood vessel that causes blood to collect under the skin. t Crush injury or crush wounds occur when a heavy object falls on a person, splitting the skin and shattering or tearing underlying structures.
