When the common fibular nerve is divided from the sciatic nerve, it travels parallel to the distal portion of the biceps femoris muscle and towards the fibular head. The small cutaneous branch arises as the common fibular nerve travels towards the fibular head. The nerve then continues down the leg on the posterior-lateral side, then posterior to the lateral malleolus where it runs deep to the fibularis tendon sheath and reaches the lateral tuberosity of the fifth toe, where it ramifies.[2][3][4]
