lateral femoral cutaneous neuropathy
Introduction
Introduction of lateral femoral cutaneous neuropathy Lateral femoral cutaneous neuropathy, also known as paresthesia. The lateral femoral cutaneous nerve is a blunt sensory nerve consisting of L2 and L3 nerves. Through the inferior gingival ligament, the fascia of the thigh is worn 10 cm below the anterior superior iliac spine, causing the distribution of the sensation due to compression or trauma. Abnormal or painful, localized hypersensitivity or decreased. Often a chronic course. Treatment can be preceded by analgesics, phenytoin, carbamazepine or partial closure. If it is not effective, it can be used for neurolysis. Common diseases are local compression, trauma, diabetes, alcohol and drug poisoning, arteriosclerosis, obesity, abdominal tumors and uterine compression in pregnancy. Some causes are unknown. Treatment of primary diseases such as diabetes, arteriosclerosis and poisoning, obesity can reduce or disappear after weight loss. Vitamin B family drugs are available. Severe pain can be oral analgesics, sedatives or carbamazepine, with vitamin B1100mg plus 654-2 acupuncture 10mg, or 2% procaine 5-10ml in the nerve through the fascia may be effective. You can also try physiotherapy, acupuncture and massage. basic knowledge The proportion of illness: 0.012% Susceptible people: no specific population Mode of infection: non-infectious Complications: abdominal mass
Cause
Causes of lateral femoral cutaneous neuropathy
The lateral femoral cutaneous nerve passes under the inguinal ligament, and the fascia of the thigh is worn 10 cm below the anterior superior iliac spine. The pressure or trauma causes the sensory area to feel abnormal or painful, local hypersensitivity or decrease. Often a chronic course. Common diseases are local compression, trauma, diabetes, alcohol and drug poisoning, arteriosclerosis, obesity, abdominal tumors and uterine compression in pregnancy. Some causes are unknown.
Prevention
Lateral cutaneous neuropathy prevention
Choose healthy foods and beverages instead of high-fat, high-sugar and high-calorie foods, eat different types of vegetables, fruits, whole grains and legumes, reduce the consumption of red meat (beef, pork and lamb), avoid eating and processing Meat, limit the consumption of high-salt foods. Try not to drink alcohol. If you drink alcohol, you should limit your daily alcohol consumption. Men should not be more than 2 cups per day, and women should not be more than 1 cup.
Complication
Lateral femoral neuropathy Complications abdominal mass
The disease has no special complications, mainly local paresthesia or mild dysfunction. It is caused by abnormal or painful distribution in the distribution area due to pressure or trauma, and local hypersensitivity or hypothyroidism. Often in a chronic course, more men than women, about 3:1, often occur on one side. It shows abnormal feeling on the lateral side of the thigh, such as ant walking, burning numbness or acupuncture, or partial hyperalgesia and loss of feeling.

Examine
Examination of lateral femoral cutaneous neuropathy
The lateral femoral cutaneous nerve is pure sensory nerve, electromyography is meaningless, and the measurement of nerve conduction velocity is also limited by the site. The stimulation of somatosensory evoked potentials in the skin is particularly important for the diagnosis of this disease. Electromyography helps identify neuropathic lesions in the femoral neuropathy and L2 segments. Various neurological examinations.
Diagnosis
Diagnosis and diagnosis of lateral femoral cutaneous neuropathy
The diagnosis of lateral femoral cutaneous neuritis is not difficult, mainly based on the diagnosis of symptoms. The disease is more common in middle-aged men, and the pathogenesis is slow and gradual. The patient feels acupuncture-like pain in the anterior and lateral skin of the thigh, accompanied by abnormal feelings 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. Frequent anesthesia can be caused by friction of clothes, exertion of force, standing or walking for too long. During the examination, the sensation, pain and temperature of the anterior and lateral skin of the thigh decreased or even disappeared, and some accompanied by skin atrophy, but the muscle did not shrink, the tendon reflex was normal, and there was no movement disorder.
