Superficial peroneal nerve

  • The superficial peroneal nerve (latin: nervus peroneus superficialis) is one of the terminal branch of the common peroneal nerve.

    The superficial peroneal nerve pierces the peroneus longus muscle, then goes between it and the peroneus brevis. Further, it passes along the lateral surface of the extensor digitorum longus, at the middle of the lower leg penetrates the crural fascia and then divides into two terminal branches: the medial dorsal cutaneous nerve and the intermediate dorsal cutaneous nerve that form seven dorsal digital nerves.

    With its muscular branches the superficial peroneal nerve innervates the peroneus longus and peroneus brevis. This nerve also provides sensory innervation to the skin of the dorsum of the foot, except the space between the first and second toe and the lateral side of the fifth toe.
