Meralgia paresthetica is a lateral femoral cutaneous neuropathy that results in symptoms of anterolateral thigh paresthesia and numbness. Its presentation due to compression of a thoraco-lumbo-sacral-orthosis (TLSO) has not been reported. We experienced a case of a 67-year-old woman who developed left lateral femoral cutaneous neuropathy as a complication of inaccurate wearing of a TLSO. The patient suffered from tingling sensation and pain in the anterolateral aspect of the left thigh without muscular weakness. An electrodiagnostic study revealed a conduction block in the left lateral femoral cutaneous nerve (LFCN) around the inguinal ligament. Ultrasonography revealed swelling of the left LFCN compared with the right side. The patient's symptoms improved after she ceased wearing the TLSO and received conservative care. Considering the complications can develop after wearing spinal orthosis, we suggest that orthosis be prescribed accurately and inspected meticulously by experts physician.
