Cervical Spondylotic Myelopathy (CSM) is a disorder characterised by the age-related deterioration of the cervical spinal cord. [1] Referred to be a range of different but related terms, a global consensus process selected Degenerative Cervical Myelopathy as the new overarching disease term . [ 2 ]
55% of facet syndrome cases occur in cervical vertebrae, and 31% in lumbar. Spinal osteoarthritis is known as spondylosis . [ 7 ] Pathology of the C1-C2 (atlantoaxial) joint, the most mobile of all vertebral segments, accounts for 4% of all spondylosis .
In cervical spondylosis, a patient may be presented with dull neck pain with neck stiffness in the initial stages of the disease. As the disease progresses, symptoms related to radiculopathy (due to compression of exiting spinal nerve by narrowed intervertebral foramen ) or myelopathy (due to compression on the spinal cord) can occur.

Identify the level of the spinal cord where myelopathy is located. This is especially useful in cases where more than two lesions may be responsible for the clinical symptoms and signs, such as in patients with two or more cervical disc hernias [11] Follow-up the progression of myelopathy in time, for example before and after cervical spine surgery
Occipito-cervical junction This disorder may result from rheumatoid arthritis, causing the hypermobility of the connection between the neck and head, resulting in paralysis or pain. [ 6 ] Cerebrovascular disease Cerebrovascular disease is a type of cervical spine disorder that can cause tetraplegia .
Central cord syndrome (CCS) is the most common form of cervical spinal cord injury (SCI). It is characterized by loss of power and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to major injury to the central corticospinal tract of the spinal cord. [1]
Neck pain, also known as cervicalgia, is a common problem, with two-thirds of the population having neck pain at some point in their lives. [1]Since there is not a universally accepted classification for neck pain, it is difficult to study the different neck pain types.
Acute disc herniation, cervical spondylosis, kyphoscoliosis, damage to the spinal column and neoplasia all could result in ischemia from anterior spinal artery occlusion leading to anterior spinal cord syndrome. Other causes include vasculitis, polycythemia, sickle cell disease, decompression sickness, and collagen and elastin disorders. [1]
