The wound in the picture above represents lacerated wound.
Wounds
- Classified into Open and Closed Wounds.
Open wounds :The main complication of an open wound is the risk of infection
Can be classified according to the object that caused the wound:
- Incisions or incised wounds – caused by a clean, sharp-edged object such as a knife, razor, or glass splinter.
- Lacerations – irregular tear-like wounds caused by some blunt trauma.
- Abrasions – superficial wounds in which the topmost layer of the skin (the epidermis) is scraped off.
- Avulsions – injuries in which a body structure is forcibly detached from its normal point of insertion.
- Puncture wounds – caused by an object puncturing the skin, such as a splinter, nail or needle.
- Penetration wounds – caused by an object such as a knife entering and coming out from the skin.
- unshot wounds .
Closed
- Hematomas – caused by damage to a blood vessel that in turn causes blood to collect under the skin.
- Crush injury – caused by a great or extreme amount of force applied over a long period of time.
Features of lacerated wound:
- Margins are irregular, ragged and uneven and their ends are pointed or blunt
- Bruising is seen either in the skin or subcutaneous tissue around the wound
- Deeper tissues are unevenly divided with tags of tissue at the bottom of wound bridging across the margin
- Hair bulbs are crushed
- Hair and epidermal tags may be driven deeply into the wound
- Less hemorrhage
- Presence of foreign matter in the wound.Often contaminated with bacteria and debris from whatever object caused the cut.Normally, pus formation occurs in about 48 hours, but in a lacerated wound it occurs slightly earlier.
- Shape and size of the wound does not correspond to the weapon used.
