Which type of wound has irregularly torn edges?

A wound with irregularly torn edges is classified as a laceration. Lacerations occur when the skin is torn or cut in a manner that does not involve a clean, straight incision. This type of wound typically results from blunt trauma or accidents, making the edges jagged and uneven. Lacerations can vary in depth and may involve different layers of skin, sometimes affecting underlying tissues as well.

In contrast, puncture wounds are characterized by a small, deep hole created by a pointed object, which does not lead to torn edges. Incisions occur when a surgical instrument or sharp object makes a clean, straight cut, resulting in smooth edges. Abrasions are superficial injuries that involve scraping away of the skin’s surface and do not feature torn edges either. Hence, identifying the characteristics of a laceration helps in distinguishing it from other types of wounds.
