Break in continuity of lining surface epithelium is defined as wound. Wound is seen in a wide variety of situations, e.g. after an accident, assault, surgery and even self-inflicted wound. Tidy wounds are clean wounds caused by sharp instruments and can be closed primarily. Untidy wounds are soiled wounds caused by crushing and avulsion injuries. In abrasion, there is irregular tearing of only superficial layers of skin as body skids on a rough surface (like road). In hematoma, there is more severe injury leading to collection of large volume of blood in tissue planes. In contusion, skin surface remains intact and subcutaneous bleeding occurs leading to swelling and skin discoloration. Incised wounds are mainly caused by sharp knife, metal and glass. Lacerated wounds are irregular and untidy wounds caused by crushing and tearing forces. Punctured wounds are caused by stabbing action of a long, thin weapon (like sword) or by a missile (like bullet). Avulsion wounds are caused by shearing force that detaches the skin from its underlying structures. Wound healing can be done by primary intention, secondary intention, and delayed primary or tertiary intention and is done in phases. Wounds are examined, treated and managed. The injuries caused by wounds are classified as simple, grievous or dangerous to life.
