Discoloration after a fracture occurs when?

• A. Discoloration occurs but takes time
• B. Discoloration occurs immediately
• C. No discoloration occurs
• D. Discoloration occurs only with heat injury

Answer: (A)

Discoloration after a fracture comes from bleeding into the surrounding soft tissues. When vessels are damaged, blood leaks into the tissue and forms a bruise (ecchymosis). That color change doesn’t show up right away; it usually develops over hours to a day or two as blood pools and the breakdown products of hemoglobin change color. So the most accurate idea is that discoloration occurs, but it takes time to become visible. In the field you may have swelling and pain right away, with the skin color changing later. Discoloration isn’t tied to heat injury and isn’t guaranteed in every fracture, but bruising from trauma commonly appears after some delay. As healing progresses, the bruise often shifts from red or blue-black to green and then yellow as it resolves.
