Which of the following describes an avulsion injury?

• A. Stretch above nerve with good recovery
• B. Pulled from the trunk
• C. Bundle of nerves attempting to self-repair
• D. Complete nerve rupture

Answer: (B)

An avulsion injury specifically refers to a situation where a body part, such as a muscle or nerve, is forcibly pulled away from its normal attachment or origin. In the context of the choices provided, the description of being "pulled from the trunk" accurately captures the essence of an avulsion injury. This type of injury typically involves a significant force that results in the detachment of a structure from the point where it is anchored, which is consistent with the understanding of how avulsion injuries occur. Considering the other options, stretching above a nerve with good recovery more closely relates to a stretch injury rather than an avulsion. The notion of a bundle of nerves attempting to self-repair may relate to nerve injuries but does not specifically define an avulsion injury. Additionally, a complete nerve rupture indicates a full break in the nerve continuity rather than the detachment characteristic of an avulsion injury. Therefore, identifying an avulsion injury as a situation where a structure is pulled from its origin fits well within the clinical definitions and presentations associated with this type of injury.
