Surgery has risks and is generally avoided as much as possible. If a treatment can be done without surgery, it really is. Some risks associated with surgery for a broken bone include damage to the tissue around the broken bone, blood loss, and infection. In your grand-daughter’s case, her doctor likely felt that she had a good chance of healing properly without surgery, so he or she took that approach. The fact that she had to have a re-adjustment to the break may not have had anything to do with the original treatment. In fact, studies seem to show that there isn’t a big difference between people who had to have a second procedure and whether they had surgery initially or not.
