Posterior tibial

Posterior Tibial

The posterior tibial is a term used in anatomy to refer to structures located near the tibia, on the posterior (rear) side. The term is most commonly used to refer to the posterior tibial artery, vein, and tendon.

Posterior Tibial Artery

The posterior tibial artery is one of the major arteries of the lower leg. It originates from the popliteal artery, travels down the posterior compartment of the leg and terminates as it divides into the medial and lateral plantar arteries which supply the foot.

Posterior Tibial Vein

The posterior tibial vein is formed by the union of the medial and lateral plantar veins. It ascends the leg in the same course as the posterior tibial artery, to which it is closely applied. It drains into the popliteal vein.

Posterior Tibial Tendon

The posterior tibial tendon is one of the most important tendons in the leg. It originates from the posterior tibial muscle, passes under the medial malleolus and attaches to the bones of the midfoot and forefoot. It plays a crucial role in maintaining the arch of the foot and inverting the foot at the ankle.

Clinical Significance

The posterior tibial structures are of significant clinical importance. Damage or disease affecting these structures can lead to serious conditions such as posterior tibial tendon dysfunction, compartment syndrome, and peripheral artery disease.
