What is termination of spinal cord?

What is termination of spinal cord?

What is termination of spinal cord?

The spinal cord ends at the intervertebral disc between the first and second lumbar vertebrae as a tapered structure called the conus medullaris, consisting of sacral spinal cord segments.

What does conus medullaris terminates at L1 L2 mean?

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.

What is Conus termination?

Conus Medullaris (CM) terminates at the second lumbar (L) vertebra, according to a consensus in the literature. In the embryological period, the medulla spinalis is the same length as the spinal canal, and along with the development it ascends cranially.

Where should the spinal cord terminate?

The spinal cord terminates at or below the upper third of L2. Care should be exercised during lumbar punctures and spinal epidural anesthesia among Africans. Intecristal line and TUP are safe landmarks to use in location of conus medullaris.

What is a synonym for the end termination of the spinal cord called?

The conus medullaris is the terminal end of the spinal cord.

Is conus terminates at L2 normal?

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).

How is conus medullaris treated?

Depending on its cause, spinal decompression surgery, radiation, and antibiotics can be used to treat the symptoms. In addition, physical therapy is also necessary to regain function.

What does it mean when the conus terminates at T12?

The conus medullaris is the terminal end of the spinal cord, which typically occurs at the L1 vertebral level in the average adult. [1] Conus medullaris syndrome (CMS) results when there is compressive damage to the spinal cord from T12-L2.

Where does conus medullaris end in adults?

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.

What tethered cord feels like?

In adults, symptoms of tethered cord often develop slowly, but they can become quite severe. Symptoms may include back pain that radiates to the legs, hips, and the genital or rectal areas. The legs may feel numb or weak, and may lose muscle. Bladder and bowel control may be difficult.

What causes conus medullaris?

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.

Is Conus terminates at L2 normal?
