Peroneal nerve neuropathy occurs in case of injuries or nerve trunk compression at any part of shin nerve division. This is the most common lower extremities neuropathy type. The nerve trauma occurs in case of peroneal bone fracture when the nerve is injured by the bone fragments. The nerve trunk compression may result of a long plaster bandage wearing, in case of a patient’s malposition during surgery, as well as vocations requiring haunches sitting. The peroneal nerve compression is also observed at prolonged legs crossing and wearing tight, misfit shoes.
Peroneal nerve neuropathy appears as foot and fingers dorsiflexion weakening, a back foot surface sensitivity decrease and ante-lateral shin surface, pain and burning sensations along the nerve. The patient cannot stand on his heels (feet “hangs down”); the so-called “cock” or “horse” gait is forming – a person has to raise his leg very high avoiding touching the floor with his toes while walking.
The amyotrophy (weight loss) of the anteroposterior shin area occurs with a chronic peroneal nerve neuropathy.
