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 .
Pimenta's point is an anatomical landmark for easy location of the posterior tibial artery or tibialis posterior artery (a peripheral pulse on the inside of the ankle). An imagined line is drawn between the bony prominence of the medial malleolus and the insertion of the achilles tendon.
Posterior tibial artery. [2] Posterior tibial vein. [1] Tibial nerve. [2] Flexor hallucis longus tendon. [2] In the tunnel, the tibial nerve splits into three different paths. [3] The medial calcaneal branches of the tibial nerve continues to the heel, while the medial plantar nerve and the lateral plantar nerve continue on to the bottom of the ...
Tibial nerve (S1, S2) Plantarflexes ankle when knee is extended; raises heel during walking; flexes leg at knee joint Plantaris: Inferior end of lateral supracondylar line of femur; oblique popliteal ligament: Weakly assists gastrocnemius in plantarflexing ankle Soleus
On inspection the clinician looks for signs of: trauma; previous surgery ()muscle wasting/muscle asymmetry; edema (swelling) erythema (redness); ulcers – arterial ulcers tend to be on the borders / sides of the foot, neuropathic ulcers on the plantar surface of the foot, venous ulcers tend on be on the medial aspect of the leg superior to the medial malleolus.
tibial nerve; common fibular nerve (also known as the common peroneal nerve) [3] popliteal vein; popliteal artery, a continuation of the femoral artery; small saphenous vein (termination) [3] Popliteal lymph nodes and vessels [3] It is of note that the common fibular nerve also begins at the superior angle of the popliteal fossa. [4]
It arises from the anterior tibial artery, and ends at the first intermetatarsal space (as the first dorsal metatarsal artery and the deep plantar artery). It carries oxygenated blood to the dorsal side of the foot. It is useful for taking a pulse. It is also at risk during anaesthesia of the deep peroneal nerve.
The fibular artery typically arises from the posterior tibial artery. [3] Therefore, the posterior tibial artery proximal to the fibular artery origin is sometimes called the tibial-peroneal trunk or tibial-fibular trunk and it could be said that the popliteal artery bifurcates into the tibial-fibular trunk and anterior tibial artery.
