Why do most fractures occur at the middle third of the femur instead of at the ends?

Simply put, it is easier to break any length of uniform material in the middle third than at the ends. The greater the distance from the end point of the material to the potential fracture point, the greater torque that is able to be applied. So it takes less force to apply the necessary torque to fracture the bone in the middle third than it does near the ends.
