Which examination finding is critical in determining the severity of an MSK injury?

The recognition of documented open injuries and soft tissue injuries is critical in assessing the severity of a musculoskeletal (MSK) injury for several reasons. Open injuries indicate that there is a breach in the skin and can often lead to complications such as infections or exposure of underlying structures to the external environment. This trauma often extends beyond what is seen externally, potentially affecting deeper tissues, compartments, or even vital structures, requiring careful evaluation and potentially more aggressive management.

Soft tissue injuries, which encompass damage to muscles, tendons, ligaments, nerves, and vessels, provide important insights into the extent of the injury. They are key indicators of the overall severity of the trauma. For example, a simple fracture may not be as clinically severe if associated soft tissues remain intact, whereas a fracture accompanied by a significant soft tissue injury could indicate substantial underlying trauma requiring urgent intervention. Thus, the documentation of these injuries forms a foundational aspect of classifying the injury severity, assisting in treatment planning and prognosis.

While visible bruising can suggest underlying trauma, and patient history is important for understanding the mechanism of injury, neither of these factors individually conveys the extent or immediate implications of the injuries as effectively as documented open or soft tissue injuries. Similarly, relying solely on a single imaging
