Fibular (Peroneal) Artery

Description

Oriented around the distal leg, ankle, and hindfoot, the fibular (peroneal) artery is traced along the posterior compartment adjacent to the fibula, coursing deep to the soleus and flexor hallucis longus and close to the interosseous membrane. From its origin off the posterior tibial artery, small muscular and nutrient branches are suggested before distal perforators pass anteriorly toward the lateral malleolar network, while calcaneal branches descend inferiorly toward the heel. Red arterial channels and paired blue venae comitantes follow the bony contours of the tibia, fibula, talus, and calcaneus, with distal vessels continuing into the foot toward the metatarsals and toes. Landmarks matter. Clinically, the fibular artery often remains a key outflow vessel when the anterior tibial or posterior tibial arteries are diseased, so appreciating its relationship to the interosseous border of the fibula and the lateral ankle helps when planning revascularization targets in chronic limb threatening ischemia. Perforators from this vessel also underpin common reconstructive options, including the fibular artery perforator flap and osteocutaneous fibula free flap, where pedicle length and distal anastomoses must be anticipated. The lateral malleolar and calcaneal branches shown in relation to the talus and calcaneus also frame operative risk zones during lateral ankle approaches and calcaneal fracture fixation. Ideal applications include lower limb anatomy teaching in gross anatomy or podiatric medicine curricula, vascular surgery and interventional radiology references discussing tibial and peroneal runoff, and orthopaedic or plastic surgery publications illustrating flap planning around the ankle and heel. It also supports patient facing education on peripheral artery disease when you want an arterial map tied to recognizable foot and ankle bones.
