Because the spinal cord stops growing before the bones of the spine, the spinal cord, in adults, ends at about the level of the vertebra L1. To get through the intervertebral foramen at the correct segment, the roots must travel down the length of the spine.

The caudaequina (Latin for "horse's tail") refers to the sack of nerve roots with a common covering at the end of the spinal cord that is the continuation of these nerve roots in the lumbar region.
Caudaequina syndrome is caused by this compression on the nerve roots.
Caudaequina syndrome is accompanied by a range of symptoms, the severity of which depend on the degree of compression and the precise nerve roots that are being compressed.
Caudaequina syndrome is defined as the compression of the nerve roots distal to L1 secondary to acute disc herniation, bony fragments, tumor, infection, or postsurgical intervention.
The incidence of caudaequina syndrome secondary to lumbar disc prolapse is reported in the literature to be between 2--6% [4].
The literature has shown that recovery after acute caudaequina syndrome cannot be clearly correlated to the rapidity of onset of the symptoms, the amount of protruded disc material, or to the severity of neurologic findings at presentation.
