Broken bones. Many of us have had them. And the causes are frequently as simple as slipping while walking to get the mail on a winter morning or carrying laundry down some stairs.
Once a bone breaks, it often must be set in proper alignment and held there in order to heal properly. This process of setting a bone is called "reduction." Setting a bone without surgery is "closed reduction” and most fractures, especially in children, are treated in this fashion. Serious or complex fractures may require open reduction -- repositioning using surgery. And then once a fracture is “set”, the broken part is often immobilized for a period of time to allow the bone to heal through a process called callous formation and then “remodeling” (a process the body uses to return a broken bone to its original shape). The whole process typically takes 6-12 weeks.
