Peroneal nerve paralysis

Peroneal Nerve Paralysis

The peroneal nerve and its branches.

The Peroneal Nerve Paralysis is a medical condition that involves the impairment of the peroneal nerve, a branch of the sciatic nerve, which innervates the anterior compartment of the leg and the lateral compartment of the leg. This condition is also known as foot drop due to the inability to lift the foot at the ankle.

Etiology

Peroneal nerve paralysis can be caused by a variety of factors, including trauma, nerve compression, neuropathy, and systemic diseases. The most common cause is compression of the nerve, often due to prolonged immobilization or cross-legged sitting.

Clinical Presentation

Patients with peroneal nerve paralysis typically present with foot drop, characterized by an inability to dorsiflex and evert the foot. This results in a high-stepping gait, also known as a steppage gait. Other symptoms may include numbness, tingling, or pain in the affected leg.

Diagnosis

Diagnosis of peroneal nerve paralysis is typically made through a combination of clinical examination and electromyography (EMG). Magnetic resonance imaging (MRI) may also be used to visualize the nerve and identify any potential causes of compression.

Treatment

Treatment for peroneal nerve paralysis depends on the underlying cause. In cases of nerve compression, treatment may involve physical therapy, orthotic devices, or surgery to decompress the nerve. In cases caused by systemic diseases, treatment of the underlying disease is necessary.

Prognosis

The prognosis for peroneal nerve paralysis varies depending on the severity and cause of the condition. With appropriate treatment, many patients can regain function in the affected foot.
