Description
An incision wound is a cut in the skin caused by a
sharp object such as a knife, broken glass, scissors
or surgeon’s scalpel. Incision wounds are ‘neat’ and
the edges of the skin are usually smooth.
A laceration is injury to the skin that results in the
skin being cut or torn open, most commonly made
by some sort of blunt trauma such as being hit with
a baseball bat. Unlike an incision, a laceration is
jagged because the skin is torn instead of cut.
An abrasion is a type of wound in which the skin is
scraped or rubbed off. Abrasions are usually
superficial wounds, meaning that only the outer
layers of skin are affected.
A contusion is a kind of closed wound, meaning that
the skin is not broken. Contusions are caused by
blunt force trauma to the skin that results in tissue
damage. When the blood vessels under the skin are
broken, blood pools under the skin causing a bruise.
A puncture wound is created when a sharp object
enters the skin and are usually small and do not
bleed a lot. Although these wounds tend to close
over quickly, they still need treatment as tetanus
infection is a possibility.
An injury in which a body structure is forcibly
detached from its normal point of insertion,
the tearing away of an attached or anchored tissue.
An immediate and transient alteration in brain
function, including alteration of mental status and
level of consciousness, resulting from mechanical
force or trauma. In many cases, there are no
external signs of head trauma.
First-degree burns cause minimal skin damage.
They are also called “superficial burns” because
they only affect the outermost layer of skin. They
usually heal within three to six days.
