![]() When injured the pressure in the compartment can increase due to bleeding and swelling inside the compartment.Įxercise increases the blood flow to muscle. What causes anterior compartment syndrome?Īnterior compartment syndrome is caused by: When the muscle does not receive oxygen it will stop working, and the muscle will die. Once the blood flow to a muscle is restricted its oxygen supply is cut off. When pressure builds-up inside the anterior compartment the blood vessels and nerves that supply the muscle are compressed, this means that the blood flow is restricted. The tibialis anterior muscle is surrounded by its own sheath of fascia this is known as the anterior compartment. ![]() The tibialis anterior is an important muscle as it both extends and inverts the foot and ankle. The anterior compartment is at the front of the leg and contains a large muscle called tibialis anterior. The four compartments of the lower leg include: ![]() There are four compartments in the leg, and each one has its own blood and nerve supply. Fascia is a flat band of fibrous tissue that separates and surrounds muscle. These four compartments in the lower leg each contain muscles that are separated by a wall of tissue called fascia. The lower leg is divided into four separate compartments. Anterior compartment syndrome occurs when the pressure within the anterior compartment builds to a dangerous level. If you think you have anterior compartment syndrome you must visit a health professional immediately so that long term damage to the muscle and the leg is prevented.Īnterior compartment syndrome describes a serious and painful condition of the leg. The result is pain at the front of the leg, near the shin. Anterior compartment syndrome occurs when the blood supply to the muscle is restricted due to a build-up of pressure inside the muscle compartment. When the artery crosses the extensor retinaculum, it changes its name to dorsalis pedis artery.Anterior compartment syndrome is a serious and painful condition that affects one of the muscles at the front of the leg. The nerve contains axons from the L4, L5, and S1 spinal nerves.īlood for the compartment is supplied by the anterior tibial artery, which runs between the tibialis anterior and extensor digitorum longus muscles. The anterior compartment of the leg is supplied by the deep fibular nerve (deep peroneal nerve), a branch of the common fibular nerve. The compartment contains muscles that are dorsiflexors and participate in inversion and eversion of the foot. Inferior third of anterior surface of fibula and interosseous membraneĭorsiflexes ankle and aids in eversion of foot Middle and distal phalanges of lateral four digitsĮxtends lateral four digits and dorsiflexes ankle Lateral condyle of tibia and superior three quarters of medial surface of fibula and interosseous membrane Middle part of anterior surface of fibula and interosseous membraneĭorsal aspect of base of distal phalanx of great toe (hallux) ![]() Medial and inferior surfaces of medial cuneiform and base of 1st metatarsal Lateral condyle and superior half of lateral surface of tibia and interosseous membrane It contains muscles that produce dorsiflexion and participate in inversion and eversion of the foot, as well as vascular and nervous elements, including the anterior tibial artery and veins and the deep fibular nerve. ![]() The anterior compartment of the leg is a fascial compartment of the lower leg. ![]()
