Femur Fracture

Femur (thighbone) is the longest and strongest bone of our body. As the femur bone is very strong it usually takes a lot of force to break it. Car crashes, for example, are the number one cause of femur fractures.

The long, straight part of the femur is called the femoral shaft. When there is a break anywhere along this length of bone, it is called a femoral shaft fracture.

Femur fractures vary greatly, depending on the force that causes the break. The pieces of bone may line up correctly or be out of alignment (displaced), and the fracture may be closed (skin intact) or open (the bone has punctured the skin).

Most femoral shaft fractures require surgery to heal. It is unusual for femoral shaft fractures to be treated without surgery. Young children are sometimes treated with a cast.
