A third cutaneous nerve, the genitofemoral, is formed from L1 and L2, and supplies a small area of skin on the upper front part of the thigh. This is the largest nerve of the lumbar plexus. Idiopathic plexopathy is another cause, being the lumbosacral equivalent of Parsonage-Turner syndrome (which affects the brachial plexus). Tumours and other local invasions can cause the plexopathy due to the compression of the plexus.
