The signs and symptoms of chronic anterior compartment syndrome include: The signs and symptoms of chronic anterior compartment syndrome are not present all of the time instead they appear during and immediately after activity. What are the signs and symptoms of anterior compartment syndrome? In the most serious cases amputation is necessary, particularly when infection is also present. The nerves that supply the muscle can also be affected leading to numbness and/or weakness in the leg. Muscles need oxygen in order to work efficiently therefore, if the blood supply is cut off the muscle will die. When the pressure inside the compartment builds to a certain level the blood vessels (which supply the muscle with the much needed oxygen rich blood) are cut off. The reason that there is not enough room is because the band of facia that forms the compartment is tightly wrapped around the muscle. In both acute and chronic anterior compartment syndrome the pressure within the compartment builds because there is not enough room inside the compartment to accommodate the extra volume caused by the increase in blood flow. Oxygen is then required to break down the glucose, therefore, the more glucose (energy) that is required by the muscle, the more oxygen that is needed to break it down. Muscles get their energy from glucose (sugar), which is transported in the blood. The extra blood flow is necessary for energy, which the muscle needs in order to function. 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. Anterior compartment syndrome is a serious and painful condition that affects one of the muscles at the front of the leg.
