A laceration is a torn, irregular, or jagged wound or an
accidental cutting wound of soft body tissue.
Lacerations commonly occur to the skin but can occur
in other living tissues such as internal organs (e.g.,
kidneys). Lacerations are often caused by blunt trauma
(e.g., falls, collision) and are also caused by sharp
objects such as knives and glass. Pieces of the object
that cause the laceration may sometimes be found in
the wound. An example would be small pieces of glass.
Depending on the shape and sharpness that causes the
laceration, the wound may appear regular/straight
(linear) or irregular (stellate). Typically, lacerations
appear irregular. They often occur during motor vehicle
accidents and fights.

When a laceration occurs, it is important to control bleeding by applying pressure to the
wound. Doing this while holding the wounded area up (above the heart if possible) for 15
minutes is usually enough to control the bleeding. If the bleeding does not stop, immediate
medical care should be sought such as calling 911. Lacerations are treated by cleansing
the area with warm  water and mild soap. Antibacterial ointment can be used for small
lacerations and then covered with a butterfly shaped band-aid. Larger lacerations are
treated by closing the wound with sutures or staples and covering it with gauze and
sometimes a wrap bandage.
