Femoral nerve entrapment syndrome

　　Common causes of compression

　　1, The femoral cutaneous nerve angles as it exits the pelvis into the thigh, and with anatomical variations, when the limbs are moved or the posture is incorrect, the nerve is subjected to persistent traction, friction, and compression, causing local tissue edema, scar formation, and thickening of the muscular fascial sheath, leading to nerve entrapment.

　　2, Fractures of the pelvis, tumors, foreign bodies, or plaster compression of the femoral cutaneous nerve can cause entrapment.

　　3, Stimulation of the nerve or compression by local scar adhesions during surgical excision of the iliac bone.

　　4, Hematomas within the fascia of the iliacopsoas muscle due to trauma or hemophilia can cause this condition.

　　In addition to general symptoms, it can also cause other diseases. This condition often complicates with femoral cutaneous nerve entrapment. Therefore, once discovered, it requires active treatment, and preventive measures should also be taken in daily life. This condition severely affects the patient's daily life, so it should be actively prevented.

　　1, Most patients have a history of lumbar hip sprains or strains, more common in women.

　　2, Pain in the affected hip, presenting as piercing, aching, or tearing pain, more severe during the acute phase, with pain radiating down the thigh but not beyond the knee, accompanied by numbness and pain in the lower limbs. The pain is deep in the region, with a blurred area and no clear boundary of distribution.

　　3. Patients often have difficulty sitting up, and when changing from a sitting position to an upright position or from an upright position to a sitting position, they feel that they cannot use their strength in the waist and legs, and the pain worsens. They cannot sit up directly and need to support themselves with their hands or be supported by others to sit up.

　　4. Limited bending activity, lifting the lower limb on the affected side is limited, but there are no signs of nerve root irritation. A rolling, elevated cord-like object can be felt directly below the midpoint of the iliac crest, which is the thickened lateral cutaneous nerve of the thigh. There is marked tenderness, severe pain, and the surrounding soft tissue is swollen and thick.

　　There is currently no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease. The patient's diet should be light and easy to digest, with more vegetables and fruits, and a reasonable diet. Pay attention to adequate nutrition. In addition, patients should also pay attention to avoiding spicy, greasy, and cold foods.

　　At the time of diagnosis, in addition to relying on clinical manifestations, auxiliary examinations are also needed. X-ray examination of this disease can exclude bony lesions of the lumbar spine, pelvis, and hip. CT and MRI can exclude tumors, tuberculosis, and inflammation.

　　What kind of food is good for the body for femoral nerve compression syndrome patients to eat:Pay attention to a light diet, eat more vegetables and fruits, and properly match the diet. Eating high-protein foods is beneficial for wound healing. Supplementing a variety of vitamins, eating fresh vegetables and fruits. You can eat various lean meats, milk, eggs, and other high-protein foods. Avoid rich, spicy, and irritating foods, and avoid foods that are easy to cause allergies and irritation, such as fish and shrimp, strong tea, coffee, and alcoholic beverages.

　　After clear diagnosis, treatment is carried out according to different etiologies. If it is caused by local scar hyperplasia or narrow muscle fascial sheath, conservative treatment (rest, physical therapy) is recommended. If ineffective, surgery can be performed to explore the pressure factors, incise the muscle fascial sheath, and remove the scar around the nerve. If the patient's nerve is deformed under pressure or has a hard feeling when touched, or if the pain symptoms are severe, nerve surgery should be performed to relieve the tension.
