What type of soft-tissue injury is characterized by a tear or cut in the skin?

• A. Contusion
• B. Avulsion
• C. Burn
• D. Laceration

Answer: (D)

A laceration is defined as a tear or cut in the skin, which can occur in various forms, such as jagged or smooth edges. This injury typically results from blunt trauma, sharp objects, or accidents that disrupt the skin's integrity. Lacerations can vary in depth and severity, depending on the force and instrument involved, and may damage underlying tissues. In contrast, a contusion refers to a bruise resulting from blood pooling under the skin due to impact without breaking the skin. An avulsion is a more severe form of injury where a portion of skin and possibly underlying tissue is forcibly torn away, often leaving a flap. A burn is caused by heat, chemicals, or electricity, leading to damage of the skin layers. Each of these injuries has distinct characteristics, making a laceration uniquely identified by its cut or tear in the skin.
