Technically, four: two thigh bones and two upper arm

common are broken arms/legs among children in  the
American midwest?

Aren't broken arms and legs usually broken in the forearm and the  lower leg? 
 I've only known one young person who had a broken femur--I  think that's a 
fairly rare break, except among the elderly who break the  femur at the hip.  I 
forget how many pounds of pressure it takes to  break the average femur, but 
it's a pretty impressive number.   The fibula and tibia in the lower leg are 
much thinner bones and more  easily broken.  Same with the radius and ulna as 
opposed to the  humerus.  The knives were made of the humerus and femur, IIRC.
