The fibula is thin, with the head of the fibula (caput fibulae) on its upper, thickened (proximal) end. On the medial side of the head is the articular surface of the head of the fibula (facies articularis cdpitas fibulae) for articulation with the tibia.
The fibula (corpus fibulae) is slightly curved and somewhat twisted along its longitudinal axis. The body distinguishes the anterior margin, the posterior margin and the medial acute interosseous margin (margo interosseus). In bone, respectively, three surfaces are distinguished: lateral, posterior and medial.
Bottom and talon the end of the fibula is thickened and forms the lateral ankle (malleolus lateralis). The medial surface of the lateral malleolus is marked by the articular surface (facies articularis malleoli). To connect with the talus bone behind the articular surface is the fossa of the lateral malleolus (fossa malleoli lateralis), to which tendons of the peroneal muscles adhere.
