Superficial Peroneal Nerve, Lateral View

Description

Running along the lateral compartment of the leg, the superficial fibular (peroneal) nerve is traced as it courses deep to the fibularis longus proximally, then descends between fibularis longus and fibularis brevis before becoming subcutaneous in the distal third of the leg. A lateral perspective places the fibula lateral to the tibia, with the nerve seen anterior to the posterior crural musculature and superficial to the fibular shaft as it approaches the ankle. Distally, its terminal branches fan across the dorsum of the foot toward the dorsal digital nerves, while the femur and patella remain superior landmarks framing the limb in profile. Orientation is clean. Nerve, bone, and compartment boundaries read clearly. This course matters because the superficial peroneal nerve is the dominant cutaneous supply to the anterolateral distal leg and most of the dorsum of the foot, and it is commonly irritated where it pierces the deep fascia. Entrapment at the fibular tunnel or fascial exit can present as burning dysesthesia over the dorsum of the foot with relative sparing of the first dorsal web space, a pattern that helps distinguish it from deep peroneal neuropathy. The lateral view also supports operative planning for anterolateral ankle approaches and for safe portal placement in ankle arthroscopy, where superficial peroneal branch injury remains a known complication. Use this illustration in lower limb anatomy teaching to reinforce compartmental relationships, or in clinical neurology and sports medicine materials discussing dorsum-foot sensory loss, peroneal tendinopathy overlap, and traction injury patterns around the fibular neck. It also suits surgical education content for fasciotomy landmarks and anterolateral ankle exposure where cutaneous nerve preservation is emphasized.
