The femur (or thighbone) can be fractured in several ways, and most commonly occur as a result of an accident. This type of injury generally requires surgery, although the procedure will depend on the nature of the injury. In some cases, external fixation is required, which involves the placement of pins and screws that are attached to a bar outside of the skin into the bones around the site of the fracture. This treatment is a temporary measure, and is generally performed before surgery can be performed.
One of the most common procedures is intramedullary nailing, in which a metal rod is placed through a small incision into the marrow canal of the femur. The rod keeps the bones in position while they heal.
