The Longest Bone in the Human Body is the Femur. The word “femur” comes from the Latin word “thigh”. Hence, it is also known as the thighbone, the hind leg, and the upper bone of the leg. Its head shapes a ball-and-socket joint with the hip. It is the only bone in the upper leg. By some measures, the femur is also the strongest bone in the human body. It is used in many medical procedures, such as hip replacements, bone grafts, and the treatment of bone cancer.
