Cervical spondylotic myelopathy (CSM) is a neck condition that arises when the spinal cord becomes compressed—or squeezed—due to the wear-and-tear changes that occur in the spine as we age. The condition commonly occurs in patients over the age of 50.
Because the spinal cord carries nerve impulses to many regions in the body, patients with CSM can experience a wide variety of symptoms. Weakness and numbness in the hands and arms, loss of balance and coordination, and neck pain can all result when the normal flow of nerve impulses through the spinal cord is interrupted.
What causes spinal stenosis?
Typically, the symptoms of CSM develop slowly and progress steadily over several years. In some patients, however, the condition may worsen more rapidly.
Patients with CSM may experience a combination of the following symptoms:
Tingling or numbness in the arms, fingers, or hands
Weakness in the muscles of the arms, shoulders, or hands. You may have trouble grasping and holding on to items.
Imbalance and other coordination problems. You may have trouble walking or you may fall down. With myelopathy, there is no sensation of spinning, or "vertigo." Rather, your head and eyes feel steady, but your body feels unable to follow through with what you are trying to do.
Loss of fine motor skills. You may have difficulty with handwriting, buttoning your clothes, picking up coins, or feeding yourself.
Pain or stiffness in the neck
