Common Peroneal Nerve

This is a condition characterised by compression of the common peroneal nerve. This results in weakness when using the foot. This is sometimes referred to as foot drop. The nerve is compressed usually around the head of the fibula at the knee joint. There might be a history of trauma or fracture of the fibula.

Foot Drop Symptoms

The presentation of symptoms is usually one of pain or numbness in the top and lateral aspect of the foot. Other symptoms include a weakness in the foot. In advanced weakness the patients might have a high stepping pattern of walking.

Common Peroneal Neuropathy Diagnosis

If there is suspicion of common peroneal neuropath, a confirmatory diagnosis is required. This is done by performing a nerve conduction study and EMG. These tests will confirm the compression of the common peroneal nerve at the knee joint. The symptoms can mimic those of a nerve compression in the lumbar spine. As such careful clinical examination is essential to make a confirmatory diagnosis.

Common Peroneal Neuropathy Treatment

Treatment options range from conservative splinting and physiotherapy to undertaking surgery. Surgical decompression of the common peroneal nerve is an effective method of treatment. This decompresses the nerve which in turn helps improve the sensation in the foot. It can improve the pain and can give the nerve a chance to recover power and strength.
