Conus medullaris syndrome is caused by an injury or insult to the conus medullaris and lumbar nerve roots. It is a clinical subset of spinal cord injury syndromes. Injuries at the level of T12 to L2 vertebrae are most likely to result in conus medullaris syndrome.
Where should the conus medullaris terminates?
Conclusions: The CM terminates most commonly at the L1-2 disc space and in the absence of tethering, the CM virtually never ends below the mid-body of L2. A CM that appears more caudal on neuroimages should be considered tethered.

A conus level of termination at L2-L3 or above is normal at any age. A conus level of termination at L3-L4 or below is abnormal (with possible exceptions occurring in premature infants and full-term newborns).

Gross anatomy The conus medullaris most commonly terminates at the L1/2 intervertebral disc level in children and adults 1-3. Extending from the conus is a delicate strand of fibrous tissue called the filum terminale that acts to give longitudinal support to the cord.
