Final answer:
Soft tissue injuries can be open or closed, and crush injury and avulsion are examples of such injuries.
Step-by-step explanation:
Soft tissue injuries can be open or closed, depending on whether the skin is broken or not. In the given options, two soft tissue injuries can be open or closed:
- Crush injury: This type of injury occurs when a part of the body is compressed between two objects or when a heavy object falls onto a body part. It can cause damage to the soft tissues and potentially break bones, resulting in an open or closed injury.
- Avulsion: An avulsion injury occurs when a portion of the skin or soft tissue is torn away from the body. It can be open or closed depending on the severity of the tear.
The other two options, incision and contusion, typically refer to closed injuries. An incision is a deliberate, intentional cut made with a sharp object such as a scalpel, and a contusion is a bruise caused by blunt force trauma without breaking the skin.
