The superficial peroneal nerve, also known as superficial fibular nerve, is one of two terminal branches of the common peroneal nerve.
origin: arises as a terminal branch of the common peroneal nerve in the lateral compartment of the leg
sensory supply: distal anterior leg and dorsal foot
Arises as one of two terminal branches of the common peroneal nerve deep to peroneus longus muscle.
Courses anteriorly and inferiorly over the lateral surface of the upper fibula between peroneus longus and brevis muscles. It continues inferiorly on the peroneus brevis and extensor digitorum longus muscles before piercing the deep fascia between one half and two thirds down the length of the leg. Now subcutaneous, it divides into two terminal sensory cutaneous branches above the ankle which descend superficial to the lateral retinaculum of the ankle.
Branches and supply
muscular twigs to the muscles of the lateral compartment of the leg
terminal cutaneous sensory branches
medial dorsal cutaneous branch (larger, supplies the medial dorsal skin of the foot)
intermediate dorsal cutaneous branch (smaller, supplies the medial dorsal skin of the foot)
