Peroneal Nerve Compression

Peroneal nerve compression is a condition that occurs when the peroneal nerve is pinched, which leads to impaired motor function and sensation in the lower extremity, specifically the ankle and foot. The peroneal nerve is a branch off of the sciatic nerve on the outside part of the lower knee.


– Motor vehicle accident

– Fracture to the bones in the lower extremity

– Remaining in certain positions for prolonged periods of time (crossing legs, laying on your side)


– Weakness in the lower extremity

– Inability to lift or hold your toes up (foot drop)

– Numbness and tingling in the foot

– Difficulty with walking


A test called an electromyogram (EMG) is used to confirm the diagnosis of peroneal nerve compression and to identify the extent and location of any nerve damage. An MRI of the lumbar spine may also be ordered to verify that the symptoms and nerve damage are not a result of compression of the nerves in the back.


Conservative management for peroneal nerve compression includes physical therapy, orthopedic shoes or splints to assist with walking, corticosteroid injections, and anti-inflammatory medications (ibuprofen, Aleve). If conservative management is ineffective in alleviating a patient’s symptoms or if significant weakness or muscle wasting is present, surgery may be required to relieve compression of the peroneal nerve.
