A broken (fractured) bone requires emergency care. Suspect a possible broken bone if your child heard or felt a bone snap, if your child has difficulty moving the injured part, or if the injured part moves in an unnatural way or is very painful to the touch.

A sprain occurs when the ligaments, which hold bones together, are overstretched and partially torn. Simply overstretching any part of the musculature is called a strain. Sprains and strains generally cause swelling and pain, and there may be bruises around the injured area. Most sprains, after proper medical evaluation, can be treated at home.
