What is a wound?
What is an open wound?
Open wounds are the wounds with exposed underlying tissue and open to the outside environment, for example, penetrating wounds. Types of open wounds include:
- Abrasions
- Lacerations
- Punctures
- Incisions
- Avulsions
What is a closed wound?
Closed wounds occur without any exposure to the underlying damaged tissue and organs and are generally caused through blunt trauma. Types of closed wounds include:
- Contusions
- Blisters
- Seroma
- Hematoma
- Crush injuries
Abrasion
Abrasions occur as a result of minor contact or scraping the skin against a rough surface, commonly through the action of falling over. Children tend to get them when falling over during outdoor activities, such as riding a bike or playing football. They typically only affect the epidermis - the outer layer of skin. However, these wounds can become more serious in certain cases where the abrasions affect a wide area of the body or are deeper into the skin tissue.
Scarring is less common with abrasions, and can be completely avoided by following a step-by-step wound healing routine. Read more on how to treat abrasions.
Laceration
A laceration wound is caused by skin tissue tearing from an external force. Due to the high level of force, the edges of the skin around the wound are not as smooth as incisions and therefore can lead to very prominent scarring if a proper wound care routine is not practiced.
Lacerations heal a lot slower in comparison to an incision wound because the tear in the skin tissue is much more jagged. They can typically affect the deeper tissues within the body such as: bones, blood vessels, muscles, ligaments, tendons, ligaments, nerves, and other internal organs.
These wounds usually affect the areas of the body that are very close to the bone, such as your knees, elbows, shins, forehead and skullcap. Read more on how to treat lacerations.
Incision
Typically, incision wounds heal much quicker than other types of wounds due to the smoother skin edges around the cut. This means scarring from deep incision wounds is less prominent in comparison to other types of wounds.
