Cauda equina syndrome (CES) occurs when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina.
Causes
CES most commonly results from
a massive herniated disc in the lumbar region.
A single excessive strain or injury may cause a herniated disc, however, many disc herniations do not necessarily have an identified cause.
The size of the disc herniation that results in cauda equina is often much larger than normal; however, if the spinal canal is smaller due to conditions such as arthritis, a smaller disc herniation can produce CES.
Potential Causes of CES
Spinal lesions and tumors
Spinal infections or inflammation
Lumbar spinal stenosis
Violent injuries to the lower back (gunshots, falls, auto accidents)
Birth abnormalities
Spinal arteriovenous malformations (AVMs)
Spinal hemorrhages (subarachnoid, subdural, epidural)
Postoperative lumbar spine surgery complications
Spinal anesthesia
