Lateral femoral cutaneous nerve entrapment syndrome is a neurological dysfunction caused by the entrapment of the nerve at various points along its pathogenic route. The common causes of compression of the lateral femoral cutaneous nerve are. The lateral femoral cutaneous nerve is angulated at the pelvic entry part of the femur, and due to anatomical variation, the nerve is subjected to continuous pulling, rubbing and squeezing when the limb activity and body position are different, resulting in local tissue edema, scar formation and thickening of the myofascial sheath, causing nerve entrapment. 2.Pelvic fractures, tumors, foreign bodies, and casts compress the lateral femoral cutaneous nerve and cause entrapment. 3, Surgical excision of the iliac bone, stimulation or local scar adhesions compressing the nerve. 4.Trauma or hemophilia occurring within the iliopsoas muscle fascia hematoma can cause this sign. The patient complains of numbness, pins and needles or burning pain in the anterolateral aspect of the femur, which is aggravated by walking and can be relieved by bed rest. There is pressure pain in the lower part of the anterior superior iliac spine and Tinel’s sign is positive there, and the anterolateral femoral sensation is decreased or hypersensitive. The symptoms were aggravated by posterior extension of the hip joint and pulling on the lateral femoral cutaneous nerve. In order to make a definite diagnosis and understand the exact cause of pressure, further X-ray examination of the lumbar spine, pelvis and hip for bony lesions or other diagnostic techniques should be used to exclude tumors, tuberculosis, inflammation or hemophilia. In case of local scar growth and myofascial sheath stenosis, conservative treatment (rest and physical therapy) is recommended. Injecting 10 ml of anti-inflammatory and analgesic solution in and around the pressure point below the anterior superior iliac spine often gives good results here. If this does not work, surgical exploration can be performed to remove the pressure-causing factors, incise the myofascial sheath, and remove the scar around the nerve. If the nerve is deformed or hard to the touch, or if the pain is severe, surgical release of the nerve should be performed.
