To Medial dorsal cutaneous nerve, intermediate dorsal cutaneous nerve Latin Nervus fibularis superficialis,
nervus peronaeus superficialis | ||
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).
It passes forward between the peroneus muscles and the extensor digitorum longus, pierces the deep fascia at the lower third of the leg, and finally divides into a medial dorsal cutaneous nerve and an intermediate dorsal cutaneous nerve. In its course between the muscles, the nerve gives off muscular branches to the peroneus longus and peroneus brevis muscles and cutaneous filaments from the integument of the lower part of the leg.
Clinical significance
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 inferior fibular nerve innervates).
