Meralgia Paresthetica Overview
The lateral femoral cutaneous nerve is a pure sensory nerve that exits the pelvis over the superior brim of the pelvis (the front of the pelvis) in the area of a tunnel created by the pelvic rim and Poupart’s ligament. This nerve can be trapped in the groin just like the median nerve can in carpel tunnel syndrome of the wrist. Symptoms that develop occur in the anterolateral (front and outside) portion of the thigh. Since the nerve is purely sensory (there is no motor portion that goes with this nerve), symptoms are numbness, paresthesias (pins and needles) and possibly pain. Weakness is not part of this syndrome.
Meralgia Paresthetica Causes
The most common causes of Meralgia Paresthetica are an overhanging belly (Dunlop’s syndrome where the belly “dun lops” over the pelvis) and by wearing a heavy utility belt (such as a carpenter or police officer does). Another common cause is prolonged positioning in surgery. Surgical positioning prone (face down-which is a common position with back surgery) utilizes pads over the anterior pelvis that the patient’s midsection rests on. The lateral femoral cutaneous nerve can be aggravated by prolonged compression due to prolonged surgery.
The condition is annoying but not dangerous. There is no muscle or joint that is supplied by this nerve.
Are you suffering from symptoms of Meralgia Paresthetica?
Would you like to consult with Dr. Corenman about your condition?
You can set up a long distance consultation to discuss your
current X-rays and/or MRIs for a clinical case review.
(Please keep reading below for more information on this condition.)
Meralgia Paresthetica Treatment
Most treatment protocols include just “waiting it out”. The nerve symptoms will generally improve over time. You can try stretching the muscles of this region to gain some relief. There are rare occasions where an injection of steroid can improve the symptoms and extremely rare cases where this nerve can be surgically decompressed.
