Degenerative cervical myelopathy is a medical condition that occurs when the spinal cord is compressed in the cervical region. This compression can cause a variety of symptoms, including pain, numbness, tingling, or muscle weakness in the arms and legs. In more advanced cases, problems such as difficulty walking, muscle stiffness (spasticity), and excessive reflexes (hyperreflexia) can also occur. If left untreated, degenerative cervical myelopathy can significantly reduce quality of life and lead to disability, including deficits ranging from quadriparesis to quadriplegia. The most common cause of degenerative cervical myelopathy is spondylosis, a condition associated with the aging and wear of the bones and cartilage in the spine. Spondylosis develops gradually over many years, and symptoms usually appear after significant damage has occurred to the spinal cord. Spondylosis usually affects middle-aged and older adults. With the aging of the population, it is predicted that the number of patients with degenerative cervical myelopathy will increase in the near future.
