Anterior compartment of the leg
The anterior compartment of the leg is one of the four compartments in the leg between the knee and foot. Muscles within this compartment primarily produce ankle dorsiflexion and toe extension.
The leg is separated into anterior, lateral, superficial posterior and deep posterior compartments by intermuscular septa and surrounded by the deep fascia of the leg.
Boundaries
- anterior: deep fascia of the leg
- posterior: interosseous membrane
- medial: lateral surface of the tibia
- lateral: anterior intermuscular septum and medial surface of the fibula
Muscles
- tibialis anterior muscle
- extensor hallucis longus muscle
- extensor digitorum longus muscle
- peroneus tertius muscle
Blood supply
- branches of the anterior tibial artery
