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

• A. Short bones
• B. Long bones
• C. Flat bones
• D. Irregular bones

Answer: (B)

The AO/OTA fracture classification is built to describe fractures of the limb bones, especially the long bones. It provides a standardized way to code which bone is involved, the segment (proximal, diaphyseal, distal), and the fracture pattern, which helps with communication and planning treatment across surgeons. Long bones like the humerus, radius/ulna, femur, and tibia/fibula are central to this system, so it’s most commonly applied there. Short bones (carpals, tarsals), flat bones (scapula, skull, pelvis bones), and irregular bones (vertebrae, others) are described using other schemes or less central to AO/OTA, so long bones are the best fit.
