Which bone is the bone of the shin that bears most weight?

• A. Tibia
• B. Fibula
• C. Ulna
• D. Radius

Answer: (A)

Weight distribution in the lower leg is determined by which bone carries the most load from knee to ankle. The shin bone, the tibia, is the larger and stronger member of the two leg bones and is positioned to bear the majority of body weight during standing and movement. Its thick shaft and its joints with the femur above and the talus below transmit forces directly through the leg. The fibula, by contrast, is thinner and mainly serves as a site for muscle attachment and helps stabilize the ankle; it carries much less weight. The other two bones are in the forearm and do not support body weight.
