Meralgia paresthetica is a neurologic disorder characterized by localized
paresthesia and numbness on the anterolateral aspect of the thigh and
involving the lateral femoral cutaneous nerve. It involves no motor
deficits. Meralgia paresthetica, which may result from a variety of causes,
has been observed as a rare complication in heart operations. Its cause
when associated with such operations is uncertain but may be prolonged
relaxed positioning on the operating table and recovery room stretcher.
Another possible cause of meralgia paresthetica after heart operations is
the "frog-leg" position of the legs during vein harvesting. Patients with
this condition should be advised of its untreatable, but benign and
self-limiting, nature.
