Fibula

Generality

The fibula is the even bone, which together with the tibia (with respect to which it is in a lateral position), constitutes the skeleton of each leg.

Located between the femur (above) and the skeleton of the foot (below), it contributes to the formation of a very important joint for foot movements: the ankle joint.
To make it easier to understand, anatomical experts divide it into three portions: the proximal end (or proximal epiphysis), the body (or shaft) and the distal end (or distal epiphysis).
The proximal end is the portion closest to the femur (but with which it does not come into direct contact).
The body is the portion between the proximal epiphysis and the distal epiphysis; it has the task of hosting different muscles of the leg and foot.
Finally, the distal end is the portion adjacent to the talus, one of the seven tarsal bones of the foot.

What is the fibula

The fibula is the even bone which, together with the tibia (equally equal), constitutes the skeleton of each leg.
In human anatomy, the leg is the region of the lower limb between the upper thigh and the lower foot.
The fibula belongs to the category of long bones, such as the tibia and femur. What makes it different from these two important bone elements is its particular slenderness: compared to the tibia and femur, in fact, it is much thinner.

LOCATION WITH RESPECT TO THE TIBIA

The fibula develops along the outer side of the tibia. With reference to the sagittal plane, this means that the fibula is lateral to the tibia and the tibia is medial to the fibula.
An explanation of the sagittal, lateral and medial plane concepts is provided in the box below.
