Cervical Spondylotic Myelopathy (CSM)

Cervical Spondylotic Myelopathy (CSM)

What is cervical spondylotic myelopathy (CSM)?

Cervical spondylotic myelopathy (CSM) is a compression of the spinal cord in your neck. A compression means pressure, pinching, or squeezing. CSM often affects adults 50 years or older. It can affect men at an earlier age than women.

Symptoms of cervical spondylotic myelopathy

Symptoms of CSM occur over time. They can include:

  • neck pain or stiffness
  • arm pain
  • numbness in your hands or weakness of your arms and legs
  • stiff fingers or legs
  • trouble using your hands or walking
  • loss of bladder or bowel control.

What causes cervical spondylotic myelopathy?

Changes in the bones, disks, and ligaments of your spine can cause pressure on the spinal cord. Sometimes growths called bone spurs add pressure to the spine. These changes often occur over time due to normal aging. Arthritis of the spine and spinal cord trauma can be other causes of CSM.

How is cervical spondylotic myelopathy diagnosed?

Your doctor will do a physical exam and review your symptoms. They will look for changes in your feeling, strength, and reflexes. The doctor also will do a magnetic resonance imaging (MRI) test. This uses radio waves to take pictures of your spine. The test can confirm if you have spinal cord compression in your neck. It also can show other problems, such as tumors, that have similar symptoms to CSM. Your doctor may have to do other tests to confirm the cause of CSM. One of these tests may be a CT scan. They also may refer you to a neurologist.

Can cervical spondylotic myelopathy be prevented or avoided?

You cannot prevent CSM. It is caused by a natural breakdown of the body as you age.

Cervical spondylotic myelopathy treatment

Mild cases of CSM can be treated with neck braces and/or physical therapy. These treatments help some symptoms, but may not provide long-term relief. Medicines can help treat symptoms, such as pain. They do not help other symptoms, such as weakness or numbness. Severe cases may require surgery. This can help reduce or relieve the compression of your spinal cord.
