lateral femoral cutaneous neuritis
Introduction
Introduction of lateral femoral cutaneous neuritis Lateral femoral cutaneous neuritis is also known as paresthesia, Bernhardt's disease, and Roth's disease. It is a disease that is abnormal in the skin of the lateral side of the femur. More common in men aged 20 to 50 years old and obese. Symptoms such as anterior lateral numbness, ant feeling, tingling, burning sensation, coldness, reduced sweating and heavy feeling can also occur, with numbness being the most common. Physical labor, when standing for too long, can be exacerbated, and symptoms can be alleviated after rest. basic knowledge The proportion of illness: 0.012% Susceptible people: more common in men aged 20 to 50 years old Mode of infection: non-infectious Complications: muscle spasm
Cause
Causes of lateral femoral cutaneous neuritis
(1) Causes of the disease
1. Lateral cutaneous nerve compression
Such as: spinal deformity, hypertrophic spondylitis, spina bifida, lumbar vertebrae, pregnancy, pelvic tumor, inguinal hernia, disc herniation, etc. can cause this disease.
2. Trauma or infection
Such as: lumbar myositis, pelvic inflammatory disease, neurosyphilis, appendicitis, pregnancy, alcoholism, sequelae of herpes zoster can induce this disease.
3. Cold and dampness are common causes of this disease.
(two) pathogenesis
1. There may be mild inflammatory cell infiltration around the small blood vessels of the dermis.
2. The cutaneous nerve can be swollen, peripheral nerve inflammation, inflammatory cell infiltration and neurodegenerative changes.
Prevention
Lateral femoral cutaneous neuritis prevention
The disease usually has two common causes, one is traumatic nerve damage, and the second is due to local inflammatory reactions involving the nerve tissue. Another factor is due to localized mass-occupying masses or nerve compression caused by lesions such as disc herniation. Therefore, clinical prevention should be carried out according to the cause, pay attention to work cautiously, and avoid causing trauma. Secondly, for the disease caused by the occupying factor and the infectious factor, the cause should be actively followed by surgery or anti-infective treatment.
Complication
Lateral femoral cutaneous neuritis Complications
The complications of this disease are mainly related to the loss of normal function of neuropathy. The most common complication is muscle weakness dominated by the nerves, as well as numbness, tingling, and paresthesia. For long-term neurological nutritional support, muscle tissue can produce atrophy. The function of the blood vessels in the site is also dominated by the nerves, which can cause local congestion and redness.
Symptom
Lateral femoral cutaneous neuropathy symptoms Common symptoms Sweating reduces shallow sensation or lack of pain and temperature loss... Thigh tingling thigh lateral pain in the anterior lateral numbness, ant sense
More common in men aged 20 to 50 years old, showing anterior numbness, ant feeling, tingling, burning sensation, cold, reduced sweating and heavy feelings can also appear, the most common numbness, manual labor When standing for too long, it can be aggravated. After the rest, the symptoms can be alleviated. The physical examination may have a slight loss or loss of degree. The main reason is that the pain and temperature are reduced and the pressure is felt. A few patients may have hypopigmentation or depression. The patient's skin may be mild and thin, slightly dry, and the mane is reduced. The disease is usually unilateral, with a few bilateral onset, chronic disease, light and heavy, and constant from month to year.
Examine
Examination of lateral femoral cutaneous neuritis
The patient felt acupuncture-like pain in the anterior and lateral skin of the thigh, accompanied by abnormal sensation, such as ant walking, burning sensation, cold sensation, and numbness. When the onset of the disease begins, the pain is intermittent and gradually becomes persistent, and sometimes the pain can be severe.
Diagnosis
Diagnosis and diagnosis of lateral femoral cutaneous neuritis
More common in men aged 20 to 50 years old, showing anterior numbness, ant feeling, tingling, burning sensation, cold, reduced sweating and heavy feelings can also appear, the most common numbness, manual labor When standing for too long, it can be aggravated. After the rest, the symptoms can be alleviated. The physical examination may have a slight loss or loss of degree, mainly due to the loss of pain and temperature and the presence of pressure, often unilateral, chronic disease, time Light and heavy, the constant month to years of unhealed, you can consider this disease.
Early leprosy was distinguished based on epidemiological history, pathological changes, pathological biopsy, including nerve fiber staining, and acid-fast bacilli.
