Step-by-step explanation:
A red flag orthopedic finding for child abuse is a metaphyseal corner fracture, commonly known as a bucket handle fracture. This type of fracture occurs at the ends of long bones, such as the femur or tibia, and is often caused by forceful twisting or pulling of a child's limb. It is important to note that bucket handle fractures are highly suspicious for child abuse, but further investigation is always needed to confirm the diagnosis.
