What is the most frequently broken bone in the human body?

If one is talking about a single bone, statistically speaking the most commonly broken bone in the body is the clavicle, commonly referred to as the collar bone.

The most common fractures in people under 75 are wrist fractures, but the wrist is not made up of a single bone, but of 8 carpal bones. After age 75, hip fractures become the most common, but this makes up only a small percentage of the population.
