Origin
The primary perforating branch of the fibular artery arises 5 cm proximal to the lateral malleolus of the fibula (Tubbs, Shoja and Loukas, 2016; Standring, 2016).
Course
The perforating branch of the fibular artery pierces the interosseous membrane and enters the anterior compartment of the leg. It anastomoses with the anterior lateral malleolar artery and descends anterior to the inferior tibiofibular syndesmosis. Occasionally, this vessel may replace the dorsalis pedis artery. In this case, the perforating branch is enlarged (Standring, 2016).
Branches
There are no named branches; however, the perforating branch of the fibular artery contributes to the lateral malleolar network via its anastomosis with the anterior lateral malleolar artery, the lateral malleolar branches of the fibular artery, and the lateral tarsal artery.
Supplied Structures
The perforating branch of the fibular artery supplies the lateral aspect of the ankle joint and the inferior tibiofibular joint.

Fibular Artery
This flap is based on the fibular artery, a branch of the posterior tibial artery 2 – 3 cm below the tendinous arch of the soleus, situated in the deep flexor compartment, giving off perforator branches which enter the lateral compartment to supply the fibula, muscles, overlying subcutaneous tissue and skin [25], Figs.
