Femoral and obturator neuropathies.

Femoral, saphenous, and obturator neuropathies have diverse causes, many of which are iatrogenic. They have overlapping, but distinct, clinical features. Electrodiagnostic testing can distinguish between these disorders and others in the differential diagnosis. Imaging studies may demonstrate the origin of the neuropathy in some cases. Conservative treatment is usually sufficient, but occasionally surgical exploration of the affected nerve is indicated.
