The<unk><unk>  is a collection of nerves at the end of the spinal cord. These nerves consist of the spinal nerves L2-L5, S1-S5 and the coccygeal nerve.<unk>  first described by Hutchinson in 1889 is due to compression of the<unk><unk>  in the lumbosacral region of the spinal canal. It is an emergency medical condition requiring acute intervention in the form of acute decompression surgery to prevent permanent neurological damage to the urinary bladder, Intestine,  sex organs  and lower limbs. The most common cause of<unk>  is lumbar disc herniation. It can be classified into two major groups,<unk>  complete with urinary retention and<unk>  incomplete. Prognosis of<unk>  depends on time from onset of symptoms to decompression and the degree of nerve damage at the time of surgery.
