Femoral neuralgia

Introduction to femoral neuralgia Femoral neuralgia, also known as Wassermann's sign, is caused by femoral nerve and branch injury. When the femoral neuralgia is painful, hot compresses and kneading pain can not alleviate the pain level, so femoral neuralgia can be ruled out. Performing special gait, the patient tries to avoid knee bending, walking at a small pace, first stretch out the foot, then drag the disease foot. Skin damage produces severe neuralgia and hyperalgesia. Femoral neuralgia can be caused by femoral nerve and branch injuries such as gunshot wounds, stab wounds, pelvic or femoral fractures, and poisoning, pelvic effusion or inflammation, varicose veins, and femoral aneurysms. Medication: Corticosteroids can eliminate local edema and adhesions of nerve trauma, promote recovery, vitamin B family, nerve growth factor, analgesics such as acetylsalicylic acid and ibuprofen. Etiology treatment: such as nerve disconnection suture, scar compression neurolysis, pelvic tumor, femoral aneurysm should be surgically removed. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: small chorea

Cause of femoral neuralgia

Cause of the disease (30%):

Femoral neuralgia can be caused by femoral nerve and branch injuries such as gunshot wounds, stab wounds, pelvic or femoral fractures, and poisoning, pelvic effusion or inflammation, varicose veins, and femoral aneurysms.

Femoral neuralgia prevention

1, the patient must first be protected from cold and dampness, especially after exercise sweating, should not be cold, should be kept dry, can not sit for a long time or lying on the cool ground.

2, as long as not in the acute period, still adhere to moderate physical exercise, help solve sports disorders, increase the range of activities, enhance muscle strength, prevent muscle atrophy, correct bad posture, enhance physical fitness, improve overall health.

Femoral neuralgia complications Complications

1. Degenerative diseases of the nervous system: motor neuron lesions, progressive spinal muscular atrophy, progressive bulbar palsy, primary lateral sclerosis, brain atrophy, Alzheimer's disease, multiple system atrophy caused by cerebellar ataxia.

2. Dyskinesia: Parkinson's disease, small chorea, dystonia, hamstrings, Huntington's disease, idiopathic tremor, poliomyelitis, tic disorder, torsion and other sports diseases.

Symptoms of femoral neuralgia Common symptoms Neuralgia, sensory disturbance, abnormal gait, edema, skin, blue, purple, change of inner thigh pain

The patient was placed in a prone position, and the examiner had pain in front of the thigh and groin when lifting his lower limb. The patient sits on both feet causing pain and must straighten. The knee reflex disappeared, and the inner side of the thigh felt dysfunctional, which may be accompanied by edema, cyanosis and other nutritional changes.

Examination of femoral neuralgia

The examination of the nervous system excludes other diseases. If necessary, do CT, nuclear magnetic, and electromyography. Should pay attention to the history of cold or infection, as well as the ankle, hip, pelvic and hip lesions, if necessary, in addition to lumbosacral X-ray, can also take ankle X-ray, anal finger, Gynecological examination and pelvic organ B-ultrasound and other examinations to determine the cause.

Diagnosis and diagnosis of femoral neuralgia

First, lumbar disc herniation: patients often have a longer history of repeated low back pain, or heavy physical labor history, often in a lumbar injury or bending after the acute incidence of labor. In addition to the symptoms and signs of typical root sciatica, there are lumbar muscle spasm, limited lumbar motion and loss of anterior lumbar flexion. The intervertebral space of the disc herniation may have obvious tenderness and radiation pain. X-ray film can have narrowed intervertebral space, and CT examination can confirm the diagnosis.

Second, the horsetail tumor: the onset is slow, gradually worsening. The disease is often unilateral root sciatica, gradually developed into bilateral. The pain at night is obviously aggravated, and the course of the disease is progressively worse. There are also sphincter dysfunction and sensory loss in the saddle area. Lumbar puncture has subarachnoid obstruction and cerebrospinal fluid protein quantitatively increased, and even Froin sign (cerebrospinal fluid yellow, self-coagulation after placement), spinal iodine angiography or MRI can be diagnosed.

Third, lumbar spinal stenosis: more common in middle-aged men, often in the early "intermittent claudication", lower limb pain after walking, but the symptoms are reduced or disappeared after walking or resting. When the nerve root or cauda equina is severely stressed, symptoms and signs of sciatica on one or both sides may be present, and the course of the disease is progressively aggravated. Treatment such as bed rest or traction is ineffective. Lumbar sacral X-ray or CT can be diagnosed.
