A fracture, also known as a broken bone, is a condition that alters the contour in the bone. There are many types of fractures. Fractures often occur when there is a high force or impact put on a bone. Fractures are common and can be caused by a number of things. People break bones in sports injuries, car accidents, falls, or from osteoporosis (bone weakening due to aging). Although most fractures are caused by trauma, they can be “pathologic” caused by an underlying disease such as cancer or severe osteoporosis. Medical care is needed immediately after a bone is fractured.
