The anterior tibial artery is a branch of the popliteal artery. [1] It originates at the distal end of the popliteus muscle posterior to the tibia. The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane.
It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. [1] [2] It ends at the proximal part of the first intermetatarsal space. Here, it divides into two branches, the first dorsal metatarsal artery, and the deep plantar artery. [2] It is covered by skin and fascia, but is fairly superficial. [2]
A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles.The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.
The limb affected by compartment syndrome is often associated with a firm, wooden feeling or a deep palpation, and is usually described as feeling tight. [5] [9] There may also be decreased pulses in the limb, poikilothermia, paralysis, and pallor along with associated paresthesia. [15] Usually, the pain cannot be relieved by NSAIDs. [16]
It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries. The deepest (most anterior) structure in the fossa, the popliteal artery runs close to the joint capsule of the knee as it spans the intercondylar fossa. Five genicular branches of the ...
Newborns and young children are also at increased PAES risk due to congenital causes. During embryonic development , the medial head of gastrocnemius migrates medially and superiorly. This migration can cause structural abnormalities, such as irregular positioning of the popliteal artery , and can account for the rare instances of entrapment ...
The popliteus muscle in the leg is used for unlocking the knees when walking, by laterally rotating the femur on the tibia during the closed chain portion of the gait cycle (one with the foot in contact with the ground). In open chain movements (when the involved limb is not in contact with the ground), the popliteus muscle medially rotates the ...
The flexor retinaculum of foot extends from the medial malleolus to the medical process of the calcaneus, and the following structures in order from medial to lateral: the tendon of the tibialis posterior muscle, the tendon of the flexor digitorum longus muscle, the posterior tibial artery and vein, the tibial nerve, and the tendon of the ...
