Meralgia paresthetica (MP) is pain or an irritating sensation felt over the anterior or anterolateral aspect of the thigh due to injury, compression, or disease of the lateral femoral cutaneous nerve (LFCN). Diagnosis of MP is based on history and examination. Nerve conduction studies are used to verify the presence of the neuropathy and rule out other causes for the symptoms. Treatment for uncomplicated or benign forms of MP includes conservative measures initially, followed by surgical intervention for chronic discomfort. Malignant pathologic processes can produce symptoms of MP and, therefore, must be ruled out before conservative treatments are initiated.
Nerve entrapment can occur at 3 potential sites including (1) beside the spinal column, (2) within the abdominal cavity as the nerve courses along the pelvis, and (3) as it exits the pelvis. The last site is the most common and may involve the sartorius muscle or may be caused by simple compression superficially near the iliac crest and ASIS by tight clothing or trauma.
