*Know what causes saddle numbness and urinary retention (pg. 678?)
CES (cauda equina syndrome) most commonly results from a massive herniated disc in the
lumbar region.
A single excessive strain or injury may cause a herniated disc.
However, disc material degenerates naturally as a person ages, and the ligaments that hold it
in place begin to weaken. As this degeneration progresses, a relatively minor strain or
twisting movement can cause a disc to rupture.
, The following are other 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

reflex.
