What are the symptoms of common peroneal nerve injury?

The symptoms of common peroneal nerve injury are related to its function and function, mainly the impairment and even loss of sensation and movement of the limb innervated by this nerve. Because the area innervated by the common peroneal nerve is mainly the sensation on the outside of the calf and the dorsum of the foot, and the strength of the extensor tendons in the calf. Therefore, if the patient has damage to the common peroneal nerve, there will be numbness on the outside of the calf and numbness on the dorsolateral side of the foot, as well as weakness of the ankle joint and thumb extension, and even loss of dorsal extension function.

Once the common peroneal nerve is damaged, it is necessary to see a doctor in time to avoid the weakness of the ankle and toe dorsal extension in the later stage, which will affect the patient's normal walking and activities.

The lower leg is the organ of the human leg "below the knee and above the ankle". The contents of the lateral bony fascial sheath include the lateral calf muscles and the superficial peroneal nerve. The contents of the anterior bony fascial sheath include the anterior calf muscles, including the third peroneal muscle, the anterior tibial artery, vein, and deep peroneal nerve.

1.Superficial structure ** thick and tight, less mobile, poor blood supply, slower healing after injury. Superficial fascial porosity. The superficial veins are the great saphenous veins and their branches. The saphenous vein ascends anteriorly through the medial malleolus to the lower leg and ascends along the medial border of the tibia.

There are two main cutaneous nerves: the saphenous nerve penetrates from the anterior wall of the adductor canal, and the descending branches of the great saphenous vein are distributed on the medial surface of the calf, anteriorly, and at the medial border of the dorsum of the foot**. The superficial peroneal nerve pierces near the junction of the middle and inferior 1 3 on the lateral side of the calf, and the deep fascial branches are distributed on the lower lateral aspect of the calf** and the dorsum of the foot**.

2.Deep structure.

1) Deep fascia The deep fascia of the calf is dense, connected to the periosteum on the medial surface of the tibia, and sends out two muscle septums on the lateral side to the deep surface, the anterior muscle septum is attached to the anterior border of the fibula, and the posterior muscle septum is attached to the posterior border of the fibula. The anterior and posterior muscle septums of the lower leg, the tibia, fibula and the interosseous membrane between them, and the deep fascia of the anterolateral region of the calf together enclose the anterior and lateral osteophyscial sheaths.

2) the contents of the periophysal sheath The contents of the lateral osteofascial sheath include the peroneal longus muscle, peroneal brevis muscle, superficial peroneal nerve and blood vessels; The contents of the anterior ossuostrial fascial sheath include the tibialis anterioris muscle, extensor longus muscle, extensor digitorum longus, third peroneal muscle, anterior tibial artery, vein, and deep peroneal nerve.

I hope I can help you with your doubts.

Common peroneal nerve injury is mainly diagnosed based on the history of trauma and clinical manifestations, and after the diagnosis of this disease, the best measures should be taken in time. Surgical exploration and surgery** at an early stage can alleviate foot drop and avoid the development of progressive deformities.

For the symptoms of common peroneal nerve injury, many patients still lack a certain amount of cognition and understanding, so let's take a look at the symptoms of superficial peroneal nerve injury!

1. Patients with partial injury will have numbness on the outside of the foot, and the numbness will gradually spread to the toes and feet with the aggravation of the disease.

2. Patients with superficial peroneal nerve injury will have dorsal flexion of the foot and dysfunction of the dorsum of the foot being turned out, and patients with more severe conditions may also have foot dropping and deformity.

3. After the superficial peroneal nerve injury, the patient will lose the function of the toes, and it is difficult for the toes to flex.

4. Patients with severe superficial peroneal nerve injury will have sensory impairment on the anterolateral and medial calves, which will not only affect the activities of the patient's limbs, but also cause great damage to the patient's body.

5. Patients will have obvious sensory disorders, and there will be disappearance of sensation in the feet and calves.

After the occurrence of superficial peroneal nerve injury, in addition to timely diagnosis and treatment measures, it is also very important to adjust dietary habits and plan life during the first disease. During the disease, you should eat more foods rich in protein, vitamins and choline, which can promote the improvement of the condition. **Do not have irritability and depressed emotions during the illness, bad emotions are not conducive to the improvement of the condition.

Maintaining a happy mood will help you better fight the disease.
