its very rare for a healthy bone to break in the exact same location that it has before and is more likely to break directly on either side of the break because of the strength that the repaired area has. you can break the same bone 20 times, but it doesnt mean that it will be in the same place all 20 times. also, it depends on the type of fracture to the bone and obviously if there are any underlying conditions that would debilitate the strength of the bone.
but anyway, who cares if you break a bone? just man up and bite your lip until the pain goes away. crash pads and broken bones are for girls, people who arent confident, and people scared of bruises.
