Abstract
Of 232 patients with evidence of lumbar spinal stenosis, 13 had symptoms of meralgia paraesthetica. Myelography demonstrated that in all but one of these 13 cases the L3-4 level was involved by stenosis; in 12 matched control patients with spinal stenosis, none had involvement at this level. We found that both the ligamentum flavum and the laminae at L3-4 level were thicker than in a control group. Decompressive laminectomy at the L3-4 level significantly reduced the area of hypo-aesthesia in the thigh, effecting complete cure in seven of the 11 cases. Meralgia paraesthetica is not uncommon in patients with spinal stenosis and is referable to changes at the L3-4 level. It seems that many cases of meralgia may have a spinal origin.
