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 tendon problems mostly occur where the tendons glide within the pulley behind the lateral malleolus. Their movement can cause irritation of the lining of the tendons. This condition is called tenosynovitis.
