The femur is the only bone in the upper portion of your leg, and it is completely covered by your thigh muscles.

These include the quadriceps quads in the front of your thigh, hamstrings in the back, gluteal muscles, and groin muscles adductors. The long, middle portion of your femur bone is called the femoral shaft. This section of your bone is about an inch and a half thick. It is also hollow like a piece of pipe.

The upper part of your femur is connected to your pelvis through the hip joint, which is shaped like a ball and socket. The lower portion of your femur bone also widens out and connects to your tibia shin bone and patella kneecap at the knee joint. A significant amount of energy is required to cause a femur fracture, most commonly after a car accident, motorcycle accident, fall from a height, or injury from a high-speed activity such as skiing or biking.

Sometimes these other injuries can be severe or even life-threatening. Sometimes paramedics or first responders will place a temporary metal brace, straps, or pillows around your injured leg to stabilize it and make it hurt less. Once you arrive at the hospital, emergency room doctors will carefully examine your whole body to look for other injuries. Several x-rays will be taken, and many times, your doctors will need to get a CT scan of other body parts.

If this is the case, doctors may put something called a "traction pin" into your leg bone above or below your knee and connect this pin to a rope with weights. This is done at the bedside under local numbing medicine. The weights can help to temporarily line up the broken ends of the bone, which can help your leg feel better before surgery.

Femur fractures almost always require surgery. The most common way to stabilize or "fix" your broken femur is to place a metal rod, called an "intramedullary nail" "IM nail" for short inside the hollow center tube of your femur. Based on factors including other injuries you may have, doctors may choose to put the rod into your femur from the top of the bone near your hip or from the bottom of the bone near your knee.

The acetabulum is covered in a layer of articular cartilage to keep the movements of the hip joint smooth as the head of the femur swivels.

Connecting the femur to the bones of the pelvis are the ischiofemoral, iliofemoral, and pubofemoral ligaments. The tibia may run vertically from the knee to the ankle, but the femur is actually set at an angle.

Because the female pelvis is typically wider than the male pelvis, females tend to have a larger Q-angle. Red bone marrow is what we typically think of when someone talks about bone marrow — in fact, in newborns, all bone marrow is red! Yellow bone marrow , on the other hand, is made up mostly of fat.
