Fun Facts about: –

  • Femur, the longest bone of our body is located between your knee and hip.
  • This bone makes up about one-fourth of a person’s overall height. It has the patella or knee cap at the bottom and pelvis at the top.
  • It allows us to use our leg for movements. The femur also helps us in standing, walking and running.
  • This bone can be considered as an organ.
  • Femur is a fairly distinct bone because of its high level of robusticity.
  • It is a weight-bearing bone.
  • It is a very long bone and it contains both red and yellow marrow.
  • Femur is very light in weight but this hollow bone is considered stronger than concrete.
  • It takes a lot of force to break this bone. Car accidents and falling from an extreme height are two most common reasons for the fracture of thigh bone.
  • This bone is connected with the hip by a ball and socket joint that allows it the freedom of movement.
  • Early complications of fracture in the thigh bone include compartment syndrome, fat embolism and shock.
