A wound is a type of injury which happens relatively quickly in which skin is torn, cut, or punctured (an open wound), or where blunt force trauma causes a contusion (a closed wound). In pathology, it specifically refers to a sharp injury which damages the dermis of the skin.
Medical professionals classify skin wounds in several ways, such as whether they are short- or long-term, and whether they are contaminated with bacteria.
These distinctions reflect differences in the nature, cause and likely course of wound, as well as treatment decisions. Short-term, open wounds are often described in 5 categories, based on the mechanism and appearance of a skin injury.
Acute wounds are often described in 5 categories, based on the mechanism and appearance of a skin injury
Abrasions occur when the skin is scraped off due to rubbing against a rough surface such as a skinned knee or elbow.
Skin Avulsion, also known as degloving, is a serious injury in which the skin is torn from the tissues beneath it and typically involves the skin catching on an object.
A Puncture wound is created when a sharp, slender object penetrates the skin and possibly the underlying tissues.
An Incision wound refers to a clean cut in the skin caused by a sharp object such as a kitchen knife.
A laceration refers to an injury caused by tissue tearing often with damage to other deeper tissue such as bones and muscles.
