What is a laceration (cut)?

A cut (laceration) occurs when the skin is sliced below the surface. A puncture wound is a deep cut that occurs when a sharp object penetrates the skin. A cut can require home treatment or the need for professional care, depending on the location and severity of the wound.

A laceration is a cut in the skin, which commonly is caused by a sharp object, such as a knife, scissors, or broken glass.



A laceration also can occur when a blunt force splits the skin. Deep lacerations may cut layers of fat and muscle, damaging both nerves and blood vessels. Bleeding may be heavy or there may be none at all.

Lacerations are not always painful, because damaged nerves cannot send pain signals to the brain, but infection can easily occur with lacerations if proper care is not given.
