Drawings of normal course of superficial peroneal nerve in leg after dissection show peroneus longus muscle (PL) exposed (A) and displaced (B). Superficial peroneal nerve (yellow) is localized deep to PL in lateral compartment of leg. It passes forward and downward and emerges (curved arrow, A) between PL and extensor digitorum longus muscle (EDL). Superficial peroneal nerve courses superficially in lateral compartment between peroneus brevis (asterisk, B) and EDL (single straight black arrow, B) muscles. Then, superficial peroneal nerve pierces crural fascia (curved arrow, B) and divides into two branches: medial dorsal cutaneous nerve (open arrow, B) and intermediate dorsal cutaneous nerve (double arrows, B).

Photographs of dissected specimen (A) and gross axial anatomic slice (B) show superficial peroneal nerve (solid white arrows) emerging between peroneus brevis muscle (PB) and anterior crural intermuscular septum (open arrows, B), which separates this muscle from extensor digitorum longus (EDL) muscle. Note that superficial peroneal nerve is in contact with deep surface of crural fascia (curved arrow, B), artery (A, black arrow) for peroneus muscles, and small vein (V, B). V = vein, PL= peroneus longus muscle.

Photograph of axial histologic slice obtained at same level as B shows superficial peroneal nerve (SPN) above peroneus brevis muscle (PB) in lateral compartment of leg. Curved arrow = crural fascia, straight arrows = anterior crural intermuscular septum, A = artery for peroneus muscles, V = vein.

Photograph of anatomic dissection of cadaveric specimen shows two nerve branches (arrows) of superficial peroneal nerve, which has divided before piercing crural fascia (asterisk).

In 59-year-old healthy female volunteer, sonograms obtained in axial plane show superficial peroneal nerve (arrows, B) and its division (arrows, C) before it pierces crural fascia (arrowheads). Insets show position of leg for scanning.
