Fibular (Peroneal) Artery

The fibular (peroneal) artery provides blood to the leg's lateral compartment. It rests deep on the back of the fibular side of the leg. It stems from the posterior tibial artery around two and a half centimeters below the popliteus muscle's lower border. This is the biggest branch that stems from the posterior tibial artery.

Then it moves diagonally toward the fibula and while held in a fibrous canal amid the tibialis posterior and the flexor hallucis longus, it goes down the posterior medial surface of the fibula. At the distal third of the leg, the fibular artery punctures the interosseous membrane. The fibular artery passes behind the tibiofibular syndesmosis and separates into lateral calcaneal branches that ramify on the posterior and lateral surfaces of the calcaneus. In the top part of its path, the deep transverse fascia of the leg and soleus covers it. In the bottom part of its path it is covered in the tissues of the flexor hallucis longus muscle.
