Lateral femoral cutaneous neuritis is seen in the following aspects: first, traumatic fracture, traumatic fracture of the hip joint compresses the lateral femoral cutaneous nerve causing the corresponding clinical symptoms; second, mechanical compression, such as the compression of the uterus after pregnancy in women, and obese patients, especially those with abdominal obesity. Third, metastatic tumors or hematomas in the abdominal cavity or abscesses that compress the lateral femoral cutaneous nerve can cause the corresponding clinical symptoms. Diabetic neuropathy can also invade the lateral femoral cutaneous nerve, such as a herniated disc in the lumbar spine can also invade the lateral femoral cutaneous nerve, causing the corresponding clinical symptoms. The lateral femoral cutaneous nerve is a downward extension of the nerve fibers of the lumbar 3 and lumbar 2, which crosses the inguinal ligament at the anterior superior iliac spine and sends out innervations to the skin of the lateral thighs causing hyperalgesia and sometimes pain, so lesions on the lateral femoral cutaneous nerve pathway may cause symptoms of lateral femoral cutaneous neuritis.
