Neuropathies that affect the lower limbs are often encountered after trauma or
iatrogenic injury or by entrapment at areas of anatomic restriction. Symptoms may
initially be masked by concomitant trauma or recovery from surgical procedures.
The nerves that serve the lower extremities arise from the lumbosacral plexus,
formed by the L2-S2 nerve roots. The major nerves that supply the lower
extremities are the femoral, obturator, lateral femoral cutaneous, and the
peroneal (fibular) and tibial, which arise from the sciatic nerve, and the
superior and inferior gluteal nerves. An understanding of the motor and sensory
functions of these nerves is critical in recognizing and localizing nerve injury.
Electrodiagnostic studies are an important diagnostic tool. A well-designed
electromyography study can help confirm and localize a nerve lesion, assess
severity, and evaluate for other peripheral nerve lesions, such as plexopathy or
radiculopathy.
