What is Common Peroneal Nerve-Neuro Facts
Channel: Neurology Sleep Centre
Date: 2021-08-11

The common peroneal nerve is the smaller and terminal branch of the sciatic nerve which is composed of the posterior divisions of L4, 5, S1, 2.

Mild peroneal nerve injuries can cause numbness, tingling, pain, and weakness. More severe injuries can be characterized by a foot drop, a distinctive way of walking that results from being unable to bend or flex the foot upward at the ankle.

The health care provider will perform a physical exam, which may show:

Loss of muscle control in the lower legs and feet
Atrophy of the foot or foreleg muscles
Difficulty lifting up the foot and toes and making toe-out movements
Tests of nerve activity include:

Electromyography (EMG, a test of electrical activity in muscles)
Nerve conduction tests (to see how fast electrical signals move through a nerve)
MRI
Nerve ultrasound
Other tests may be done depending on the suspected cause of nerve dysfunction, and the person's symptoms, and how they develop. Tests may include blood tests, x-rays, and scans.

Treatment aims to improve mobility and independence. Any illness or other cause of neuropathy should be treated.
