Abstract
BackgroundThe superficial peroneal nerve is a branch of common peroneal nerve. There are reports about the variant course and distribution of this nerve. The sural nerve arises from the tibial nerve in the popliteal fossa. The variations of the above nerves described here are unique and provide significant information to surgeons dissecting lower limb.Case presentationThe present case is about some important anatomic variations observed in left lower limb of approximately 55 - year - old male cadaver. The variations were; high division of superficial peroneal nerve into medial and lateral branches, lateral branch descending in the anterior intermuscular septum in a peroneal tunnel before piercing the deep fascia and variant distribution of sural nerve on the dorsum of the foot. The probable clinical significances of the variation are discussed.ConclusionAwareness of anatomical variations of superficial peroneal and sural nerves such as those presented here becomes important to avoid injury in real clinical situations.
Highlights
The superficial peroneal nerve is a branch of common peroneal nerve
It is at first deep to peroneus longus, and passes anteroinferiorly between the peroneus longus and peroneus brevis and between extensor digitorum longus and peronei to pierce the deep fascia in the distal third of leg, where it divides into medial and lateral branches

Summary
The superficial peroneal nerve begins at the bifurcation of common peroneal nerve behind the head of the fibula. The lateral branch descended in the anterior intermuscular septum in a peroneal tunnel of 11.2 cm length, pierced the deep fascia of lateral compartment about 12 cm proximal to the ankle (Figure 3) and gave cutaneous branches to the adjacent skin of front of leg. Both medial and lateral branches were providing motor branches to peroneus longus and brevis before piercing the deep fascia.

The present findings coincide with K3 variety of Kosinski's classification of termination of the dorsal nerves of the foot [12]
