Spinal cord stimulation for treatment of meralgia paresthetica.

Abstract

BACKGROUND:

Meralgia paresthetica is a clinical syndrome of pain, dysesthesia or both, in the anterolateral thigh. It is associated with an entrapment mononeuropathy of the lateral femoral cutaneous nerve. Diagnosis of meralgia paresthetica is typically made clinically and is based on the characteristic location of pain or dysesthesia, sensory abnormality on exam, and absence of any other neurological abnormality in the leg. The majority of patients with meralgia paresthetica respond well to conservative treatment.

OBJECTIVE:

To present a case of intractable meralgia paresthetica in which conservative treatment options failed but which was successfully treated with a spinal cord stimulator.

CASE REPORT:

A 44-year-old woman presented to the pain clinic with a one-year history of bilateral anterolateral thigh pain. History, physical exam, and diagnostic work-up were consistent with meralgia paresthetica. Multiple medications, physical therapy, and chiropractic therapy were not successful for this patient. In addition, local anesthetic/steroid injection of the lateral femoral cutaneous nerve provided only short-term relief. Ultimately, a spinal cord stimulator was implanted after a successful temporary percutaneous trial. Two months after the implantation, she continued to have 100% pain relief, worked full-time, was physically active, and no longer required any pain medication including opioids.

CONCLUSION:

An implanted spinal cord stimulator may be an ideal treatment for intractable meralgia paresthetica after conservative treatments have failed because it is not destructive and can always be explanted without significant permanent adverse effects.
