Tibialis posterior muscle
The mucous sheaths of the tendons around the ankle. Medial aspect. (Tibialis posterior labeled at top center.)
Latin	musculus tibialis posterior
Gray's	subject #129 484
Origin	tibia, fibula
Insertion	navicular, medial cuneiform
Artery	posterior tibial artery
Nerve	tibial nerve
Actions	inversion of the foot, plantar flexion of the foot at the ankle
Antagonist	Tibialis anterior muscle

The tibialis posterior is the most central of all the leg muscles, and is located in the posterior compartment of the leg.

It is the key stabilizing muscle of the lower leg.

Blood is supplied to the muscle by the posterior tibial artery, and innervation is via the tibial nerve.

Origin and insertion

The tibialis posterior muscle originates on the inner posterior borders of the tibia and fibula. It is also attached to the interosseous membrane, which attaches to the tibia and fibula.

The tendon of tibialis posterior muscle descends posterior to the medial malleolus and terminates by dividing into plantar, main, and recurrent components. The plantar portion inserts into the bases of the second, third and fourth metatarsals, the second and third cuneiforms and the cuboid. The main portion inserts into the tuberosity of the navicular and the plantar surface of the first cuneiform. The recurrent portion inserts into the sustentaculum tali of the calcaneus.

Function

As well as being a key muscle and tendon for stabilization, the tibialis posterior also contracts to produce inversion and assists in the plantar flexion of the foot at the ankle. The tibialis posterior has a major role in supporting the medial arch of the foot. Dysfunction of the tibialis posterior, including rupture of the tibialis posterior tendon, can lead to flat feet in adults, as well as a valgus deformity due to unopposed eversion when inversion is lost.
