Key structures within the fascial compartment affected by increased compartment pressures include muscles, nerves and vasculature. Use the power of 3D anatomy to better understand the muscle compartments of the anatomy. Lower leg ACS is a condition in which increased pressure within a muscle compartment surrounded by a closed fascial space leads to a decline in tissue perfusion and compromises motor and sensory function. anterior compartment contains tibialis anterior, extensor hallucis longus, extensor digitorum longus, fibularis tertius, tibialis anterior artery and vein, and deep fibular nerve. As it travels around the leg it envelops the external surface of the muscle compartments and blends with the periosteum overlying the tibia. The tibialis anterior muscle is located alongside the lateral surface of the tibia. Surrounding the entire leg is deep crural fascia. Lateral condyle of the tibia, anterior crest of the fibula intermuscular membrane between it and the tibialis anterior, lateral margin of the interosseous membrane, the septum between it and the peroneus longus, and fascia of the leg near the tibial originĮach tendon, located on the dorsal surface of the toe to which it goes, divides into three fasciculi: the intermediate, attached to the dorsum of the base of the middle phalanx and two lateral, which converge to the dorsum of the base on the distal phalanx. Muscles in the Anterior Compartment of the Leg Tibialis Anterior.

Medial surface of the first cuneiform and the base of the first metatarsalīranch from the common peroneal and another from the deep peroneal Distal part of the lateral condyle of the tibia, lateral surface of the proximal half of the shaft of the tibia, adjacent interosseous membrane, overlying fascia near the condyle of the tibia, and intermuscular septum between it and the extensor digitorum longus
