Which of the following is NOT a sign of potential complications after a fracture?

Swelling reducing over time is not a sign of potential complications after a fracture. In fact, it typically indicates that the healing process is progressing as expected. After a fracture, some initial swelling is normal due to inflammation and the body's natural response to injury. As healing occurs, this swelling should gradually subsist, suggesting that the body is effectively managing the trauma.

In contrast, persistent pain, loss of function, and pale color in the skin surrounding the injury can all indicate complications such as inadequate healing, infection, or circulation issues. Persistent pain may suggest that the fracture has not properly healed or that there are associated soft tissue injuries. Loss of function could indicate complications such as joint involvement, while a pale skin color might signal compromised blood flow to the area, which is a critical condition that needs immediate attention. Thus, recognizing the reduction of swelling as a positive sign is crucial in the recovery from fractures.
