A broken bone is also known as a fractured bone, which is usually abbreviated as “fx” in your medical cart or notes. In the most general sense, a broken bone occurs when there is too much pressure placed on a bone, causing the bone to split or break. There are different types of broken bones that can occur as a result of a car accident. Some types of fractures are more painful than others, while certain fractures will also require surgical intervention to repair the damage or stabilize the area of the injury
