Where Should The Conus Medullaris Terminates

The conus medullaris most commonly terminates at the L1/2 intervertebral disc level in children and adults 1-3. Read the full answer On average, the conus terminates at the middle third of the L1 vertebra but can be located as high as the middle third of the T11 vertebra or as low as the middle third of L3 vertebra. via

What does conus medullaris terminates at the level of L1 mean?

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. via

What is conus terminates at T12?

The conus medullaris, the termination of the spinal cord, is located anywhere between T12 and lower L2. 9. The conus is the last segment of the cord from which nerve roots arise; none arise from the filum. via

Is conus terminates at T12 normal?

The termination of conus medullaris with respect to the vertebral levels in normal population was described in various studies. [1][2] [3] [4] Previous reports have documented that the conus reaches to the adult position before 2 years of age, with a range span extended from T12 to L3. via

Where should the spinal cord terminate?

The spinal cord terminates in the lumbar spine. The exact point of termination varies among individuals; most commonly, it terminates at the level of the L1 or L2 vertebrae. via

Is conus terminates at L1 normal?

On average, the conus terminates at the middle third of the L1 vertebra but can be located as high as the middle third of the T11 vertebra or as low as the middle third of L3 vertebra. via

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. via

What causes Conus Medullaris syndrome?

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. via

What happens if the conus medullaris is damaged?

Conus medullaris syndrome is a type of incomplete spinal cord injury that is less likely to cause paralysis than many other types of spinal cord injuries. Instead, the most common symptoms include: Severe back pain. Strange or jarring sensations in the back, such as buzzing, tingling, or numbness. via

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. via

What is the difference between cauda equina syndrome and conus medullaris syndrome?

The symptoms and signs of cauda equina syndrome tend to be mostly lower motor neuron (LMN) in nature, while those of conus medullaris syndrome are a combination of LMN and upper motor neuron (UMN) effects (see Table 1, below). via

How do I know if I have cauda equina syndrome?

Typical symptoms of cauda equina syndrome include: Neurological symptoms in the lower body. Weakness, tingling, or numbness in the legs, and/or feet on one or both sides of the body is a common symptom. Lower body weakness or numbness may make it difficult to walk or stand. via

What level does spinal cord terminate?

The spinal cord tapers and ends at the level between the first and second lumbar vertebrae in an average adult. The most distal bulbous part of the spinal cord is called the conus medullaris, and its tapering end continues as the filum terminale. via
