Approach Considerations

Nerve conduction studies and electromyography

Evaluation for femoral nerve dysfunction includes nerve conduction studies (NCS) and needle electromyography (EMG). NCS should include sensory studies of the saphenous nerve and motor studies of the femoral nerve. When evaluating femoral NCS, results on the symptomatic side should be compared with those on the asymptomatic side. On EMG, the quadriceps should show neuropathic changes.

Imaging studies

In cases of suspected retroperitoneal hematoma, an emergent computed tomography (CT) scan of the pelvis should be performed.

In cases in which the etiology is not apparent, magnetic resonance imaging (MRI) or CT scanning of the pelvis may help in localizing the site of compression and may define the etiology (eg, tumor, abdominal aortic aneurysm, iliac aneurysm).
