Tibiofibular trunk (or tibioperoneal trunk) is an arterial trunk representing the direct continuation of the

popliteal artery The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branche ...

(the first branch of the popliteal artery) branches off from it. The tibiofibular trunk terminates by bifurcating into two terminal branches: the

posterior tibial artery The posterior tibial artery of the lower limb is an artery that carries blood to the posterior compartment of the leg and plantar surface of the foot. It branches from the popliteal artery via the tibial-fibular trunk. Structure The posteri ...

. This is the most common configuration of the origins of these arteries, however, many other anatomical variations exist. The vessel here described as the tibiofibular trunk may alternately be regarded as the initial portion of the posterior tibial artery, with the fibular artery instead regarded as its branch.
