Introduction

Introduction Loss of sensory inner leg is one of the symptoms of high-level injury to the femoral nerve injury. The high-level injury of the femoral nerve injury is characterized by loss of sensory anterior medial and medial calf.

Cause

Cause

Gunshot injuries, knife stab wounds, iatrogenic injuries, etc. are more common.

Examine

an examination

Related inspection

Vagus nerve examination

Exercise

If the injury is above the armpit, the iliopsoas and quadriceps are paralyzed, and the hips and knees cannot be flexed. For example, the injury is below the branch of the diaphragm, and only the knee can not be stretched.

2. Feeling

High-level lesions manifested as sensory loss of the medial anterior medial and medial calves. Low-level injury, which can be a simple saphenous nerve injury, manifests the sensory disturbance of the medial calf.

3. Nutrition

The inside of the calf is susceptible to trauma, frostbite and burns.

History of trauma, iliopsoas and quadriceps, can not bend knees and knees. Loss of sensation in the anterior, medial and calf medial, EMG examination is helpful for diagnosis.

Diagnosis

Differential diagnosis

The diagnosis should be differentiated from the following symptoms:

1. Sensory loss of medial anterior medial and medial calf

High-level lesions in the femoral nerve injury manifested as loss of sensory anterior medial and medial calf. Low-level injury, which can be a simple saphenous nerve injury, manifests the sensory disturbance of the medial calf. The femoral nerve comes from the lumbar plexus, descending along the surface of the diaphragm, penetrating the inguinal ligament and dividing it into the anterior and posterior 3-4cm femoral arteries. It occupies the sartorius muscle, the quadriceps muscle, the cutaneous branch to the anterior part and the hidden The innervation of the inner skin of the calf. Femoral nerve injury is rare, and most of them are surgical injuries. The main clinical manifestations after injury are knee extension obstruction caused by quadriceps paralysis and sensory disturbance of anterior and posterior femoral medial. If it is an operation, it should be repaired as soon as possible.

2. Loss of the lateral and instep of the calf

Diagnosis of common peroneal nerve injury: History of injury, due to the extension of the calf muscles and the length and length of the humerus, it is a ptosis.

a. Exercise: If the injury is above the armpit, the iliopsoas and quadriceps are both paralyzed, and the hips and knees cannot be flexed. For example, the injury is below the branch of the diaphragm, and only the knee can not be stretched.

b. Feeling: High-level injury manifests as loss of sensory anterior medial and medial calf. Low-level injury, which can be a simple saphenous nerve injury, manifests the sensory disturbance of the medial calf.

c. Nutrition: The inside of the calf is susceptible to trauma, frostbite and burns.
