Schematic drawing of a cross section of the right lower leg. The anterior compartment contains the anterior tibial muscle (TA), extensor hallucis longus muscle (EHL) and the extensor digitorum longus muscle (EDL). The neurovascular bundle, comprising the deep peroneal nerve (arrow), runs between anterior tibial muscle and extensor hallucis longus muscle. The lateral compartment contains the peroneus longus muscle at this level. The superficial peroneal nerve (arrowhead) courses anteriorly in the lateral compartment along the intermuscular septum between the anterior and lateral compartments
