Fascial compartments of leg

On the human body, the limbs can be divided into segments, such as the arm and the forearm of the upper limb, and the thigh and the leg of the lower limb. If these segments are cut transversely, it is apparent that they are divided into multiple sections. These are called fascial compartments, and are formed by tough connective tissue septa. Compartments usually have separate nerve and blood supplies from their neighbours. All the muscles within a compartment will generally be supplied by the same nerve.


The (lower) leg is divided into four compartments by the interosseous membrane of the leg, the transverse intermuscular septum and the posterior intermuscular septum:[1]

Compartment Muscles Neurovascular structures
Anterior compartment of leg Tibialis anterior, Extensor hallucis longus, Extensor digitorum longus, Peroneus tertius Deep peroneal nerve, Anterior tibial vessels
Lateral compartment of leg Fibularis/peroneus longus, Fibularis/peroneus brevis Superficial peroneal nerve
Deep posterior compartment of leg Tibialis posterior, Flexor hallucis longus, Flexor digitorum longus, Popliteus Tibial nerve, Posterior tibial vessels
Superficial posterior compartment of leg Gastrocnemius, Soleus, Plantaris Medial sural cutaneous nerve
