Superficial peroneal nerve
In 81% of cases, the superficial peroneal nerve arises as one of the two terminal branches of the common peroneal nerve at the level of the fibula's neck.
In about 9% of cases, it begins between the fibular neck and the knee joint.
The nerve originates above the knee joint line in the remaining 10%.
The nerve runs over the upper part of the fibula deep to the peroneus longus muscle, then through the peroneus longus to run between it and the peroneus brevis muscles.
It descends more superficially between the peroneus brevis and extensor digitorum longus muscles.
At the junction of the upper two-thirds and lower one-thirds, the nerve pierces the deep (crural) fascia before becoming superficial through the peroneal tunnel (approximately 12 cm above the ankle)

The nerve is blocked to relieve symptoms of entrapment and to allow for painless surgical procedures for pathologies over the dorsum of the foot in the area supplied by the superficial peroneal nerve.
The ultrasound-guided block outperforms the landmark-guided block in terms of results and complications.
