Superficial peroneal nerve
Adjacent to the neck of the fibula, the common peroneal nerve divides into two terminal branches - the superficial and deep peroneal nerves. The superficial peroneal nerve passes anteriorly and inferiorly between the peroneal muscles and the belly of extensor digitorum longus before piercing the crural interosseous membrane to become cutaneous in the distal 1/3 of the leg. The superficial peroneal nerve then divides into its two terminal branches; the medial and intermediate dorsal cutaneous nerves. Both of these nerves descend through the anterior compartment of the leg, passing superficially to the extensor retinaculum to enter the dorsum of the foot. The specific course of each of these nerves is variable, however, given their superficial nature, they are often quite easy to visualize on your subject.
