The femur, or the thigh bone, is the largest and strongest bone in the human body. It takes a lot of force to break this bone. In a car accident, victims experience forces similar to those felt by astronauts during take-off. Unlike astronauts, Missouri accident victims have little protection from these forces, and forces of 2 to 3 Gs are large enough to break femurs and cause other serious injuries.

In this article, our Clay County, MO auto accident lawyers offer answers to frequently asked questions about femur fractures.

What are the symptoms of a femur fracture?

  • Severe leg pain
  • Increased pain when the leg is moved
  • Inability to move the injured leg
  • Deformity in the leg
  • Swelling
  • Bruising or discoloration
  • The bone may protrude through the skin


How are femur fractures diagnosed?
If you have been injured in a Missouri car crash and you suspect your leg is fractured, you should go to the emergency room immediately. The emergency room doctor will examine your leg and take several x-rays. He will also conduct tests to check the nerves and blood vessels in your leg. Since broken femurs rarely occur without injuries, you will be screened for hidden injuries.

There are three categories of femur fractures:


  1. Proximal femur fracture: These are fractures to the femur that occur near the hip bone. These fractures are treated as hip fractures because they involve the hip joint. You can read about the treatment of hip fractures in our article, "Missouri Car Accident Hip Fractures: Who Is At Risk?
  2. Supracondylar femur fractures: This is an injury to the portion of the femur immediately above the knee joint. These types of fractures damage the cartilage of the knee joint. 
  3. Femoral shaft fractures: These fractures involve the portion of the thigh below the hip and above the knee.


How are femur fractures treated?
Treatment of a femur fracture depends on the location and severity of the injury. A simple fracture in which the bones are not displaced can be immobilized with a cast. If there is displacement, crushing of the bone, multiple fractures, or the knee or hip are involved, the injury victim will require surgery.

A broken femur bone may take six months to heal. If there are other injuries, healing may take longer. After the bone has healed, the accident victim will need physical therapy to improve range of motion and strength in the leg.
