What Is the Posterior Tibial Artery?

The posterior tibial artery is a direct continuation of the iliac artery. After the lower edge of the diaphragm is separated, it descends between the superficial and deep layers of the calf flexor muscles, passes through the medial malleolus, and passes through the deep side of the flexor support band into the soles of the feet. A final branch. The post-embryonic arteries nourish the tibia and posterior calf muscles.

Anatomy of the posterior tibial artery:

The posterior tibial artery is a continuation of the iliac artery and is the larger of the terminal branches of the arteries. It descends between the shallow and deep layers of the flexor muscles behind the calf to the medial process of the medial condyle and heel tubercle. Artery two terminal branches. There are two accompanying veins throughout the posterior tibial artery.

Posterior tibial artery branch

Peroneal artery: The perforating branch is generally 3.5 cm above the lateral malleolus, with an incidence rate of 93%. It passes through the muscle and interosseous membrane to the ankle. The peroneal branch of the peroneal artery is sometimes significantly enlarged and continues as a dorsal foot artery. 5 cm above the ankle joint, a branch from the anterior tibial artery is often issued to the outside and below, and anastomosis with the peroneal branch of the peroneal artery. The peroneal branch of the peroneal artery is 5 to 6 cm above the tip of the lateral malleolus, passes through the interosseous membrane immediately adjacent to the fibula margin, and travels between the short peroneus and long toe extensors, and then divides into the ascending and descending branches. The descending branch descends along the fibula margin and coincides with the ankle artery at the tip of the lateral malleolus. In the descending process, the descending branch sends periosteal branches to the tibia and the fibula distally: the tibial periosteal branch is often the communication branch between the anterior tibial artery and the peroneal branch of the peroneal artery and is distributed at the lower end of the tibial bone and the medial malleolus. Three branches distributed at the distal fibula and lateral malleolus. The periosteum flaps of the tibia and lower fibula of the peroneal descending branch of the peroneal artery can be used to repair the bone defect of the middle and lower tibial bone in antegrade or retrograde transposition. Because this pedicle is not the main blood vessel of the lower extremity, it will not affect the blood of the lower leg and foot after removal. for. The above three arteries form a rich vascular anastomosis near the ankle. The posterior tibial artery and the peroneal artery are located on the inner and outer sides of the Achilles tendon at the back of the heel.

The tibial nourishing artery, which enters the tibial bone marrow cavity from the tibial nourishing hole, is the largest in the whole body. The tibial nourishing artery is emitted at the beginning of the posterior tibial artery, and descends along the back of the tibia below the sacral line. After the 1-2 muscle branches are issued, it enters the bone through the tibial nourishing hole to nourish the bone.

The medial plantar artery is the smaller of the two posterior branches of the posterior tibial artery. It travels between the abductor hallucis and short toe flexor muscles and is distributed on the muscles of the thumb and the skin on the inside of the plantar. The stroke of the posterior tibial artery is equivalent to starting the tibial tuberosity plane at the midline behind the calf and reaching the midpoint of the medial process of the medial malleolus and the calcaneal tuberosity. The posterior tibial artery travels within the middle interval of the deep muscles, and the superficial muscles must be removed when exposed. The upper third of the right calf, because the posterior tibial nerve is on its inner side, is not ligated here to avoid injury.
