- 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. These compartments usually have a separate nerve and blood supply to their neighbours. The muscles in each compartment will often all 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:
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 Peroneus longus, 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
