Most doctors wont even treat a broken bone for several days anymore. They prefer to wait until the swelling goes down before treating it. My son broke his arm last year playing football and when I took him to the emergency room, they just did a make shift splint and told me to follow up with an orthopedic in about a week. They no longer cast them at the hospital because of swelling. That day when I started calling around to orthopedic's to schedule an appointment, they all said "one week" in order to allow time for the swelling to go down. So no, it is not child abuse.
