CERVICAL SPONDYLOTIC MYELOPATHY (Spinal Cord Compression)
One of the most common neck conditions that occurs with age is cervical spondylotic myelopathy (CSM). Over time, the normal wear-and-tear effects of aging can lead to a narrowing of the spinal canal. This compresses — or squeezes — the spinal cord. CSM can cause a variety of symptoms, including pain, numbness, and weakness (AAOS, 2015).
Symptoms usually begin after the age of 50, but can occur earlier if there was an injury to the spine at a younger age. Many people with CSM will have steady progression of their disease. Once symptoms start, they tend to continue. Typically, the disease progresses slowly over several years. In about 5% to 20% of people, CSM worsens more rapidly.
