Superficial peroneal nerve

The superficial peroneal nerve or superior fibular nerve, innervates the peroneus longus and peroneus brevis muscles and the skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot (with the exception of the first web space, which is innervated by the deep peroneal nerve).Cutaneous nerves of the right lower extremity. Front and posterior views.Nerves of the dorsum of the foot. The superficial peroneal nerve or superior fibular nerve, innervates the peroneus longus and peroneus brevis muscles and the skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot (with the exception of the first web space, which is innervated by the deep peroneal nerve). Superficial peroneal nerve is the main nerve of the lateral compartment of the leg. It begins at the lateral side of the neck of fibula, and runs through the peroneal muscles. In the middle third of the leg, it descends between the peroneus longus and peroneus brevis muscles, and then reaches the anterior border of the peroneus brevis to enter the groove between the peroneus brevis and extensor digitorum longus under the deep fascia of leg. It becomes superficial at the junction of upper two-thirds and lower one-thirds of the leg by piercing the deep fascia. Superficial peroneal nerve gives off several branches in the leg. At the junction between the upper two-thirds and lower one-thirds of the leg, superficial peroneal nerve is divided into medial dorsal cutaneous nerve (medial branch) and intermediate dorsal cutaneous nerve (lateral branch). Injury to the nerve can result in an inability to evert the foot and loss of sensation over the dorsum of the foot (with the exception of the first web space between the great toe and the second toe, where the deep fibular nerve innervates).
