The peroneal nerve, also known as common fibular nerve, is one of the branches of the sciatic nerve. It is the most commonly injured nerve of the lower leg due to its location. Peroneal nerve injury and disease may arise due to various possible causes ranging from trauma, compression or infection.
Once it has been determined that the irritation of the common peroneal nerve is located at the fibular neck, one most commonly confirms this diagnosis on physical exam. The common peroneal nerve can be palpated where it crosses the lateral aspect of the fibula about 2 centimeters distal to the fibular head. In addition, about 3 to 4 cm proximal to this, it courses out from under the undersurface of the long head of the biceps femoris.
