Cauda equina syndrome refers to injury to the nerves still within the spinal cord as they form a "horse's tail" to exit the lumbar and spinal regions. This usually occurs with fractures below the L2 level and results in flaccid-type paralysis. The type of bladder and bowel impairment that results from such an injury depends on the level of the injury and can be problematic, particularly for women, who may have difficulty with urinary drainage and incontinence.
