The lateral femoral cutaneous nerve is formed in the lower back from branches of the second and third lumbar spinal nerves which combine to form a single nerve (on each side) soon after emerging from the spinal column. The nerve passes through the interior of the pelvis and exits the pelvis near the outer border of the inguinal (groin) ligament before making a downward turn to run beneath the skin of the outer thigh.
The course of the nerve can vary from person to person and even from side to side in the same person. In about 25% of people the nerve splits into branches before reaching the inguinal ligament, and there can be up to 5 branches. This variability might make some people more vulnerable to nerve-injury than others. Read more…

Pressure within the pelvis, as from pregnancy, obesity and (rarely) tumors, can injure the portion of the nerve within the pelvis. And as Freud's physician surmised, the nerve is particularly vulnerable to injury from external pressure at the inguinal ligament, as from corsets, wide belts and tight pants. However, a cause for meralgia paresthetica is not always found, as was apparently the case when Freud had it.
The nerve can also be injured during a wide variety of surgical procedures, including orthopedic, vascular, gynecological, abdominal, hernia and even stomach-stapling operations. In a recent series of spinal surgery cases in Taiwan, 60 out of 252 patients experienced meralgia paresthetica as a complication of the surgery. Fortunately, in all cases it resolved within two months.

Diagnosis of this condition is usually made from the history and the physical examination, with the key features being numbness and unpleasant sensations on the side of the thigh. Other conditions can mimic meralgia paresthetica, for example, a pinched spinal nerve in the lower back, or impairment in the nearby femoral nerve that also emerges from the pelvis at the inguinal ligament. Tests of muscle and nerve electricity--electromyography and nerve conduction studies--can help resolve ambiguous cases.

Treatment of meralgia paresthetica has not been studied by the gold-standard method of randomized, controlled trials involving a comparison group of untreated patients. So in choosing appropriate treatment all we have to go on are collections of cases published in medical journals. Because many cases turn out well without drastic treatments, conservative approaches are tried first. Weight loss, removal of tight garments, completion of pregnancy and simple watchful waiting can all be effective.
