AO/OTA fracture classification is used for describing fractures of which bones?

• A. Short bones
• B. Flat bones
• C. Sesamoid bones
• D. Long bones (e.g., femur, tibia, humerus, radius/ulna)

Answer: (D)

AO/OTA fracture classification is used for describing fractures of long bones. This system was created to provide a common language for detailing fractures of the major limb bones—the femur, tibia, humerus, and the radius/ulna—so clinicians can describe where the fracture is, how it’s patterned, and how severe or complex it is. By encoding bone, segment (proximal, middle, distal), and fracture pattern (with modifiers for displacement or fragmentation), it supports consistent planning, treatment decisions, and comparison across cases and studies. Short bones, flat bones, and sesamoid bones have different classification schemes because their shapes and typical fracture patterns differ, so the AO/OTA system is most widely applied to long bones.
