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.
One of the first things to do in the assessment of possible common peroneal nerve entrapment is to verify that the irritation in the common peroneal nerve at this location is not due to a lumbar spine cause, such as a herniated disk or spinal stenosis, and is truly localized to the common peroneal nerve itself.
