Superficial Peroneal Nerve

Description

Running superficially in the distal lateral leg, the superficial fibular (peroneal) nerve emerges from the lateral compartment between fibularis longus and fibularis brevis, then becomes subcutaneous in the distal third of the leg before crossing anterior to the ankle. Distal to the lateral malleolus it divides into the medial and intermediate dorsal cutaneous nerves, which spread across the dorsum of the foot over the extensor tendons and metatarsals toward the toes. Nearby osseous landmarks likely include the fibula, talus, calcaneus, cuboid, metatarsals, and phalanges, with tendon profiles suggesting fibularis tendons laterally and extensor tendons anteriorly. Relationships matter here: the nerve lies superficial to the deep fascia and generally anterior to the fibula and lateral malleolus as it fans out on the dorsal midfoot. Entrapment and iatrogenic injury of the superficial peroneal nerve are common problems in the distal leg and ankle because the nerve pierces the deep fascia and then runs in a vulnerable subcutaneous course. This view helps you localize symptoms of dorsal foot dysesthesia or burning pain that spare the first dorsal web space (deep fibular nerve territory), a pattern seen in superficial peroneal neuropathy, ankle sprain traction injuries, and after arthroscopy portal placement. It also supports planning for regional anesthesia, since a superficial peroneal nerve block targets these dorsal cutaneous branches near the ankle. Educators can drop this plate directly into lower limb dissection manuals, neuroanatomy teaching decks on cutaneous innervation, and orthopaedic or podiatry texts covering ankle approaches and portal safety zones. Clinicians may also use it for patient-facing explanations of dorsal foot numbness after fibular fracture fixation, fasciotomy, or lateral ankle ligament reconstruction.
