Cauda equina syndrome

Cauda equina  (CES) refers to a group of symptoms that occur when nerves in the cauda equina become compressed or damaged. These nerves roots connect the  and peripheral nervous system.

Symptoms

CES can lead to pain, numbness, and weakness in the lower back,  area and legs; "foot drop"; problems with bowel or bladder control; sexual dysfunction; and even paralysis.

Medical emergency

CES is considered a medical emergency and requires hospitalization. Therefore, people with unexplained onset of symptoms should seek medical attention as soon as possible and consult with a  or neurosurgeon.

Cause of CES

CES is most commonly caused by a herniated disk in the lumbar spine. Other causes of CES may include a birth abnormality (such as spina bifida), a spinal infection or , trauma or injury to the lower back, spinal stenosis, a spinal arteriovenous malformation, and complications after spinal surgery.

Diagnosis

CES can be difficult to diagnose since symptoms vary and they may mimic other conditions. Tests that may be used to diagnose CES include X-rays, and myelogram (a special type of  of the spinal canal).

Treatment

Treatment usually targets the underlying cause of CES. Symptoms are more likely to improve or go away if the cause is identified quickly and treatment begins right away.

Complications

Some may have permanent neurologic impairment, chronic pain, and/or mental health problems due to the impact of symptoms on social life and relationships.
