What has been the experience with a cervical myelopathy surgery for the spine..?

Usually good: It depends on the severity of the pressure, how long it has been there, if there has been spinal cord damage. Usually decompression keeps myelopathy from worsening. The condition usually improves unless there is severe damage to the cord before something is done. An experienced spine surgeon can give prognosis in a given person.

It is indicated: When diagnosed secondary to cord compression, it will get worse without surgery but this progression varies from patient to patient. Surgery is indicated to prevent progression but it is unpredictable as to extent of recovery but the earlier it is diagnosed with the least objective findings and symptoms, the better the prognosis. Cord changes on imaging also tend to suggest a worse prognosis.
