<P> The fibula or calf bone is a leg bone located on the lateral side of the tibia , with which it is connected above and below . It is the smaller of the two bones , and , in proportion to its length , the slenderest of all the long bones . Its upper extremity is small , placed toward the back of the head of the tibia , below the level of the knee joint , and excluded from the formation of this joint . Its lower extremity inclines a little forward , so as to be on a plane anterior to that of the upper end ; it projects below the tibia , and forms the lateral part of the ankle - joint . </P>
