Common peroneal nerve injury usually affects the patient’s walking to varying degrees, such as uneven force on the soles of the feet, wobbly walking, or even inability to walk on their own. Common peroneal nerve injury is a symptom of atrophy and paralysis of the peroneal muscle or tibialis anterior muscle group that is mostly seen in traumatic fracture, tumor compression and other factors. If the patient with mild peroneal nerve damage, he can walk, but because of the uneven force on the foot, he should pay more attention to safety when walking to avoid falling. Patients with moderate peroneal nerve damage can generally walk appropriately, but they will mostly show weakness of the limb when walking, the heel of the foot leaving the ground, and eventually walk with a wobbly and unsteady gait. If the peroneal nerve injury is too severe, patients may not be able to lift their feet to walk, and need assistive devices to help them walk; if the peroneal nerve is damaged due to fracture, a plaster cast is needed to promote nerve recovery, and walking is generally not recommended at this time. Patients are advised to seek timely medical examination and targeted treatment and management.
