AI overview
The fibula is the smaller of the two bones in your lower leg, running along the outer side of the tibia (shinbone) and connected to it at the top and bottom. While it's a slender bone that doesn't bear as much weight as the tibia, it plays an important structural role by providing attachment points for muscles and ligaments that support the leg and ankle.

It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below 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.
==Structure== The bone has the following components: Lateral malleolus Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial side of the lower end of the fibula, and a rough concave surface on the lateral side of the tibia.
