Lumbar Plexus Neuralgia

What is lumbar plexus neuralgia?

The nerve roots that arise in the spinal column make up a network of nerves in the back. This is known as a plexus. Each nerve that goes to the leg and the foot originates in this network. Lesions of the lumbar plexus are injuries to this network of nerves in the back and may be the cause of pain.


The most common cause of this condition is a serious accident, but damage to this network of nerves can also be caused by: sports injuries, stab wounds, and operations in this area.

Signs and symptoms

As well as varying degrees of paralysis and loss of feeling, neuropathic pain in the legs is the biggest problem.  This pain is continually present and is of a burning or stabbing character.  At a later stage there are attacks of stabbing and shooting pain.  This pain normally occurs at the ends of the limbs: the lower arm, the hand and/or the fingers.

How is lumbar plexus neuralgia diagnosed?

The neurological examination particularly focuses on paralysis and loss of feeling in the legs.

Do I need additional examinations?
