Superficial Peroneal Nerve, Anterior View

Description

Running along the anterolateral compartment of the leg, the superficial fibular (peroneal) nerve is traced from its origin as a terminal branch of the common fibular nerve near the fibular neck, then coursing distally along the lateral side of the tibia and fibula toward the ankle. After becoming subcutaneous in the distal third of the leg, it divides into the medial dorsal cutaneous nerve and intermediate dorsal cutaneous nerve, which spread over the dorsum of the foot toward the metatarsals and toes. Bony landmarks remain in clear anterior relation throughout, including the femur, patella, tibia, fibula, and the tarsals, metatarsals, and phalanges. Proximally, the sciatic nerve and its division into tibial and common fibular components are contextualized against the pelvis and thigh. An anterior rendering like this is the workhorse view for teaching why superficial fibular nerve symptoms present as dorsolateral foot paresthesia with relative sparing of the first dorsal web space, which is supplied by the deep fibular nerve. Entrapment where the nerve pierces the crural fascia, or traction injury in inversion ankle sprains, makes the distal subcutaneous course and branching pattern clinically concrete. The relationship to the fibular neck also matters, since common fibular neuropathy at this level can mimic or exceed deficits expected from a more distal superficial branch lesion. Localization starts here. Use this figure in gross anatomy and neuroanatomy instruction, in EMG and nerve conduction reporting guides, and in orthopaedic or sports medicine publications discussing lateral leg pain, ankle sprain neuropraxia, or safe incision planning for anterolateral approaches to the distal leg. It also fits patient education handouts for dorsal foot numbness patterns when paired with dermatome maps. Anatomical accuracy verified by SciePro's Medical Advisory Board.
