Common peroneal nerve damage

Introduction to common peroneal nerve damage Common peroneal nerve injury caused spasm and atrophy of the tibialis anterior and tibialis anterior muscle groups. The patient could not reach out, lift the foot, lift the toe and reach the valgus, which was a horseshoe. When walking, the patient lifts the foot to make the hip joint and the knee joint excessively flex. When the foot falls, the forefoot tip hangs down, and then the whole foot is used to land, like a horse or chicken gait, or a cross-threshold gait. The sensory disturbance is distributed in the anterolateral and dorsum of the calf, including the first toe gap. Achilles tendon reflexes are not affected. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: Diabetes Lead poisoning

Causes of common peroneal nerve damage

(1) penetrating injury, humeral head fracture trauma, traction can damage the superficial peroneal nerve and deep nerve.

(2) under pressure: the total nerves around the humeral neck are most vulnerable to prolonged sputum

Common peroneal nerve damage prevention

Avoid trauma, to prevent the main, the patient's foot drooping and varus, a little carelessness can sprain the external hemorrhoids when walking, so educate patients to prevent secondary damage.

Common peroneal nerve damage Complications, diabetes, lead poisoning

1. Severe patients can eventually cause spasm and atrophy of the tibialis anterior and tibialis anterior muscle groups, the foot is drooping, and the valve gait is formed.

2. If caused by diabetes, it will be combined with diabetic foot.

3. If caused by lead poisoning, combined with epilepsy and mental retardation.

Common peroneal nerve damage symptoms Common symptoms Foot and toe can not dorsiflexion across the threshold gait outside the calf and the back of the foot... Sensory disorder

The patient showed that the foot and the toes could not dorsiflexion, the foot was drooping, the walking was high, and the toes first landed, showing a cross-threshold gait, anterior lateral leg and foot and back feeling.

Examination of common peroneal nerve damage

Electrophysiological examination, through electromyography and evoked potential examination, to determine the extent, extent, recovery and prognosis of nerve injury.

Diagnosis and differentiation of common peroneal nerve damage

1. Early or cauda equine tumors of motor neuron disease may show sagging of one foot and resemble common peroneal nerve paralysis, but all have loss of Achilles tendon reflex or other muscles of lower limbs, indicating that the lesion has exceeded the common peroneal nerve.

2. The common injury of the common peroneal nerve and the sacral nerve has a sensory disturbance at the base of the foot, and the foot and toes cannot be deformed.
