Pressure on the lateral femoral cutaneous nerve in the thigh causes meralgia paresthetica. This sensory nerve, unlike those listed earlier, can be tested by nerve conduction techniques, although reliability of the results is questionable. The underlying muscles are carefully separated to expose the lateral femoral cutaneous nerve in the upper thigh area. The lateral femoral cutaneous nerve is a branch of the lumbar plexus, exiting the spinal cord between the L2 and L3 vertebrae. It can start as slightly uncomfortable but grow to become extremely painful and debilitating. The lateral cutaneous femoral nerve originated from L3-L5 nerve roots, and the saphenous nerve from L4-L6 nerve roots. By Chris Faubel, MD. Difficulty lifting up the thigh. The trunk of femoral nerve lies in the iliac fossa between the iliacus and psoas major muscles. View Notes - 27. Both originate from the lumbar plexus but are different nerves. The most common site of entrapment occurs at the inguinal ligament. Furthermore, in L2 root lesions the analgesia is very slight because of the overlap between L2 and L3, whereas in lesions of the lateral cutaneous nerve, there is This nerve has a purely sensory function. release of compressive devices.
