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.
Peroneal nerve palsy results when the nerve at the top of the calf on the outside of the knee is compressed. This leads to a condition called foot drop, in which it becomes difficult to lift the foot. Neuropathy can affect nerves that control muscle movement (motor nerves) and those that detect sensations such as coldness or pain (sensory nerves). In some cases, it can affect internal organs, such as the heart, blood vessels, bladder, or intestines.
