Anterior Tibial Artery, Medial View

Description

Running distally from the popliteal artery, the anterior tibial artery passes through the proximal opening in the interosseous membrane and enters the anterior compartment, then descends on the anterior surface of the interosseous membrane between tibialis anterior medially and extensor digitorum longus laterally. A medial perspective emphasizes its relationship to the tibia, with the vessel positioned lateral to the tibial crest and accompanied by paired venae comitantes, while the more superficial great saphenous vein tracks along the medial leg anterior to the medial malleolus. Distally, the artery becomes the dorsalis pedis artery on the dorsum of the foot as it crosses the ankle joint between the malleoli. Landmarks matter. Clinically, this course explains why anterior tibial artery injury can complicate proximal tibial fractures or iatrogenic dissection around the interosseous membrane, and why acute compartment syndrome of the anterior compartment threatens distal perfusion even when proximal pulses seem preserved. A medial view also helps teach palpation and Doppler localization of the dorsalis pedis pulse and clarifies common variants, including hypoplastic anterior tibial artery with dominant peroneal supply to the dorsum of the foot. Vascular bypass planning and endovascular access both benefit from understanding where the vessel hugs the interosseous border versus where it becomes more superficial near the ankle. Use this artwork in lower limb anatomy teaching for medical and PA curricula, in vascular surgery or interventional radiology references describing tibial runoff, and in patient-facing materials explaining peripheral arterial disease and pulse checks at the foot. It also fits cleanly into diagrams on saphenous vein harvest and venous mapping by contrasting superficial and deep pathways in one frame.
