What is the tibialis posterior?

Tibialis posterior is the most central and deepest muscle located in the posterior aspect of the leg. Together with popliteus, flexor hallucis longus and flexor digitorum longus, it forms the deep group of muscles of the posterior compartment of leg. These muscles are located posterior to the tibia, fibula and interosseous membrane.

What is the origin and insertion of the tibia posterior?

Origin and insertion Tibialis posterior is attached between the bones of the leg and the foot. The muscle consists of two parts close to its origin; medial and lateral. The medial portion arises from the upper two-thirds of the posterior surface of tibia, inferior to the soleal line, and from the posterior surface of interosseous membrane of leg.

How is blood supplied to the tibialis posterior?

Blood is supplied to the muscle by the posterior tibial artery . The tibialis posterior muscle is suppled by the tibial nerve . The tibialis posterior muscle is a key muscle for stabilization of the lower leg. It also contracts to produce inversion of the foot, and assists in the plantarflexion of the foot at the ankle.

Can the tibialis posterior tear without tearing?

Elongation can also occur without tearing, with as little as 1 cm of elongation resulting in dysfunction 1. Tibialis posterior can tear in its 1: Tibialis posterior dysfunction can be secondary to 3:

Where is the tibialis posterior located?

(Tibialis posterior labeled at top center.) Fibularis brevis and longus, antagonist to the inversion. The tibialis posterior muscle is the most central of all the leg muscles, and is located in the deep posterior compartment of the leg. It is the key stabilizing muscle of the lower leg .

What is posterior tibial tendon dysfunction?

Posterior tibial tendon dysfunction is a problem that occurs in one of the tendons on the inner side of the ankle . A review of your anatomy is helpful in understanding how this occurs. The posterior tibial muscle attaches to the back of the shin bone; the posterior tibial tendon connects this muscle to the bones of the foot.

How is blood supplied to the tibialis posterior?

Blood is supplied to the muscle by the posterior tibial artery . The tibialis posterior muscle is suppled by the tibial nerve . The tibialis posterior muscle is a key muscle for stabilization of the lower leg. It also contracts to produce inversion of the foot, and assists in the plantarflexion of the foot at the ankle.

How does the posterior tibial tendon attach to the shin bone?

A review of your anatomy is helpful in understanding how this occurs. The posterior tibial muscle attaches to the back of the shin bone; the posterior tibial tendon connects this muscle to the bones of the foot. It passes down the back of the leg, not far from the Achilles tendon, then turns under the prominence of the inner side of the ankle.

What supplies blood to the tibialis posterior muscle?

The recurrent portion inserts into the sustentaculum tali of the calcaneus . Blood is supplied to the muscle by the posterior tibial artery . The tibialis posterior muscle is suppled by the tibial nerve . The tibialis posterior muscle is a key muscle for stabilization of the lower leg.

What is the posterior tibial artery?

The posterior tibial artery is one of the largest arteries in the lower leg. It branches off from the popliteal artery , a blood vessel behind the knee that is a continuation of the femoral artery. This is important because the femoral artery, along with the femoral vein, is vital for circulating blood between the lower body and the heart.

What blood vessels supply the proximal metaphysis of the tibia?

Results: The proximal metaphysis of the tibia was found to have a rich extraosseous blood supply provided primarily from vessels from the popliteal artery, the anterior tibial artery (ATA) laterally, and the posterior tibial artery (PTA) medially.

Where does the recurrent portion of the tibialis posterior insert?

The recurrent portion inserts into the sustentaculum tali of the calcaneus . Blood is supplied to the muscle by the posterior tibial artery . The tibialis posterior muscle is suppled by the tibial nerve .
