The gradual degeneration of the spine often takes the form of cervical spinal stenosis , which is the narrowing of the spinal canal in the neck. Some people are born with a narrow spinal canal congenital spinal stenosis and may experience myelopathy sooner than others if further narrowing occurs. Bulging or herniated discs and bone spurs in the neck are other forms of spinal degeneration that can press on the spinal cord and cause myelopathy. Besides the gradual wear and tear of the spine, cervical myelopathy can also be caused by the ossification hardening of the ligaments surrounding the spinal cord, such as posterior longitudinal ligament and ligamentum flavum.
The ossification of posterior longitudinal ligament OPLL is more common. This means that the soft tissue that connects the bones of the spinal column becomes less flexible and slowly turns into bone ossification. As the ligament becomes thicker, it starts taking up more space and putting pressure on the spinal cord, which leads to myelopathy. The neck portion of the spine is the most common location for OPLL ossification.
Whiplash injury or other cervical spine trauma. The earlier cervical myelopathy is diagnosed, the more successful the treatment is expected to be. Conduct electrical tests to measure how well the nerves in your arms and hands communicate with your brain through the spinal cord.
There are some nonsurgical options for relieving cervical myelopathy symptoms, including physical therapy and a cervical collar brace. However, to eliminate the compression of the spinal cord and prevent worsening of the condition, surgery is often necessary.
There are a few surgical procedures your doctor may recommend for treating cervical myelopathy. Widening of the spinal canal laminoplasty can be a good motion-sparing option for some patients.
However these researchers considered this specifically in a subsequent study [2] and found that this was not the case. However it should not be used to define the timing of surgery. It is unclear whether or not it predicts outcome, but the recent findings would suggest this is not the case. Tetreault et al.
