What it means
The femur is your thigh bone — the longest and strongest bone in the human body. It runs from your hip down to your knee. At the top, a rounded ball fits into the hip socket to form the hip joint. At the bottom, it connects with the tibia and kneecap to form the knee. The femur supports your full body weight when you stand and walk. Inside, it contains bone marrow that produces blood cells. A femur fracture is a serious injury often requiring surgery. Your doctor may order an X-ray, CT scan, or MRI to evaluate this bone.
