The femur is the thigh bone. In humans, it is the longest, most voluminous, and strongest bone. The average human femur is 48 centimeters (19 in) in length and 2.34 cm (0.92 in) in diameter and can support up to 30 times the weight of an adult. [cite web|url=http://thelongestlistofthelongeststuffatthelongestdomainnameatlonglast.com/long254.html|title=The Longest Human Bone|publisher=thelongestlistofthelongeststuffatthelongestdomainnameatlonglast.com|accessdate=2007-12-14] It forms part of the hip (at the acetabulum) and part of the knee.

The word "femur" is Latin for "thigh". Theoretically in strict usage, "femur bone" is more proper than "femur", as in classical Latin "femur" means "thigh", and "os femoris" means "the bone within it".

In medical Latin its genitive is always "femoris", but in classical Latin its genitive is often "feminis", and should not be confused with case forms of "femina", which means "woman".

Intercondylar Fossa

The intercondylar fossa is present between the condyles at the distal end of the femur. In addition to the intercondylar eminence on the tibial plateau, there is both an anterior and posterior intercondylar fossa (area), the sites of anterior cruciate and posterior cruciate ligament attachment, respectively.

In other animals

Parallel structures by the same name exist in other complex animals, such as the bone inside a ham or a leg of lamb. The name femur is also given to the most proximal full-length jointed segment of an arthropod's leg.
