Lower extremity of femur Lower extremity of femur The lower extremity of femur (or distal extremity) is the lower end of the thigh bone in human and other animals, closer to the knee. It is larger than the upper extremity of femur, is somewhat cuboid in form, but its transverse diameter is greater than its antero-posterior; it consists of two oblong eminences known as the condyles.
