Clinical Description

Overview of the Peroneal Nerve

The peroneal nerve, a branch of the sciatic nerve, is responsible for motor and sensory functions in the lower leg and foot. It innervates muscles that control foot dorsiflexion (lifting the foot) and eversion (turning the foot outward). Injury to this nerve can lead to significant functional impairments, including foot drop, loss of sensation, and difficulty in walking.

Mechanism of Injury

Injuries to the peroneal nerve can occur due to various mechanisms, including:
- Trauma: Direct trauma from fractures, dislocations, or penetrating injuries.
- Compression: Prolonged pressure on the nerve, often seen in cases of prolonged immobilization or tight casts.
- Stretching: Injuries resulting from sudden movements or falls that stretch the nerve beyond its limits.

Symptoms

Patients with a peroneal nerve injury may present with:
- Motor deficits: Weakness in dorsiflexion and eversion of the foot, leading to a characteristic foot drop.
- Sensory deficits: Numbness or tingling in the lateral aspect of the lower leg and the dorsum of the foot.
- Pain: Localized pain at the site of injury or referred pain along the nerve pathway.

Diagnosis

Diagnosis typically involves:
- Clinical examination: Assessing motor function, sensory loss, and reflexes.
- Electromyography (EMG): To evaluate the electrical activity of the muscles innervated by the peroneal nerve.
- Imaging studies: MRI or ultrasound may be used to visualize any structural abnormalities or compressive lesions.

Treatment

Management of peroneal nerve injuries may include:
- Conservative measures: Rest, physical therapy, and the use of ankle-foot orthoses (AFO) to support foot function.
- Surgical intervention: In cases of severe injury or entrapment, surgical decompression or repair may be necessary.
