laceration

Monday 23 March 2009

A laceration is an irregular tear in the skin produced by overstretching. It may be linear or stellate, depending on the tearing force. Typical of a laceration are the bridging strands of fibrous tissue or blood vessels across the wound, not seen in an incision.

The immediate margins of the laceration are frequently hemorrhagic and traumatized. In contrast, an incision is made by a sharp cutting object, such as a knife (scalpel) or a piece of glass.
