Head of Fibula
The structure indicated is the
head of the fibula. The two bones of the leg are the
tibia and the
fibula. The fibula is the smaller of the two bones and lies laterally. The head of the fibula is an expansion of the fibula at the proximal end, and is flattened superiorly and medially forming a surface for articulation with the
lateral condyle of the tibia. The head of the fibula provides the point of attachment for several muscles and ligaments, including the
biceps femoris and the
lateral collateral ligament (fibular collateral ligament). Just below the head of the fibula, the
common peroneal nerve winds around the
neck of the fibula – a point of exposure making it susceptible to damage. Learn more about the anatomy of the
fibula in this tutorial.
