The common peroneal nerve is the lateral of the two terminal branches of the sciatic nerve
From its origin in the popliteal fossa it descends infero-laterally just medial to the tendon of biceps femoris. It winds around the fibular neck and divides into its two terminal branches: The superficial peroneal nerve and the deep peroneal nerve
In the knee region, the common peroneal nerve gives the following branches before dividing into its terminal branches:
– Articular branches: The lateral genicular nerves – The peroneal communicating nerve which joins the sural nerve from the tibial nerve – The lateral cutaneous nerve of calf which arises within the popliteal fossa and supplies the skin over the upper part of the lateral part of the leg
