Which long bone is the most commonly fractured in the body?

• A. Femur
• B. Fibula
• C. Humerus
• D. Tibia

Answer: (D)

Tibias fractures are most common because the tibia bears nearly the full weight of the body during standing and walking, often with direct impact or twisting injuries. It runs along the front of the leg with relatively little soft-tissue coverage, especially along the anterior/shin area, making it particularly vulnerable to trauma. That combination of high load and exposed location leads to a high incidence of fractures, especially midshaft injuries. The femur, while the strongest and usually protected by surrounding muscles, still fractures mainly in high-energy trauma; the fibula is smaller and often fractures with the tibia or in isolated injuries less frequently; the humerus, though commonly injured, does not reach the same fracture frequency as the tibia among long bones.
