What does the anterior and posterior tibial artery supply?
The posterior tibial artery is a branch of the popliteal artery that supplies the posterior compartment of the leg and the sole of the foot….Posterior tibial artery.
| Origin | Popliteal artery |
|---|---|
| Supply | Proximal end of fibula, tibia, soleus muscle, deep flexors of leg, skin and fascia of posterior leg and heel, muscles of sole of foot |
What does the anterior tibial artery do?
The anterior tibial artery is responsible for the blood supply of the anterior crural compartment. At the anterior aspect of the ankle joint, the anterior tibial artery becomes the dorsalis pedis artery.
Why is the posterior tibial artery important?
The posterior tibial artery supplies oxygenated blood to the posterior compartment of the leg and the plantar surface of the foot.
What muscles does the anterior tibial artery supply?
- anterior compartment of the leg. tibialis anterior muscle. extensor hallucis longus muscle. extensor digitorum longus muscle.
- posterior compartments of the leg. superficial posterior compartment of the leg (calf) triceps surae muscle.
- lateral compartment of the leg. peroneus brevis muscle. peroneus longus muscle.
Where does the posterior tibial artery begin and end?
Posterior tibial artery. The posterior tibial artery commences at the lower border of the popliteus as one of the two terminal branches of the popliteal arteries, the other being the anterior tibial artery. It supplies the back of the leg, i.e. the two posterior compartments and the sole of the foot.
Is the anterior tibial artery a perforating branch?
The anterior tibial artery may occasionally be of small calibre or rarely, absent. In this case its supply is functionally replaced by the perforating branches of the posterior tibial artery or by the perforating branch of the fibular (peroneal) artery.
What are the four compartments of anterior tibial syndrome?
Four compartments located in the lower leg may be involved in exertional compartment syndrome: anterior, lateral, superficial posterior, and deep posterior. The anterior compartment contains the deep peroneal nerve and the anterior tibial artery. The lateral compartment contains the superficial peroneal nerve.
What causes burning sensation in the posterior tibial artery?
This can occur from an ankle fracture or sprain, arthritic changes, tenosynovitis, or fluid collection. The primary complaint is foot pain, often described as burning. Many patients will isolate the burning to the sole of the foot. The posterior tibial nerve has three branches: calcaneal, medial plantar, and lateral plantar.
