Abstract

According to Spalteholz,1 the common peroneal nerve usually branches from the sciatic nerve at the apex of the popliteal space. It runs along the medial margin of the biceps femoris muscle on the dorsal surface of the lateral head of the gastrocnemius muscle distad and laterad, and then behind the head of the fibula to the lateral margin of the shaft of the fibula, where it divides into its two terminal branches, the deep and the superficial peroneal nerve, both of which pass through the canal located in the origin of the peroneus longus muscle. The deep peroneal nerve innervates the tibialis anterior muscle and the extensor muscles of all the toes and supplies sensory fibers to the skin of the dorsal surfaces of the adjacent halves of the first and second toes. The superficial peroneal nerve innervates the peroneal muscles and supplies sensory fibers to the skin of
