Many patients with cervical spondylosis who consult online are concerned about the need for surgery for cervical spondylosis, so it is necessary to explain this. The most early manifestation of cervical spondylosis is neck pain and discomfort, sometimes dizziness and panic, etc. At this stage, the intervertebral disc is still normal and the spinal cord is not compressed. At this stage, the intervertebral disc has degenerated and the spinal cord is slightly compressed by the disc, so surgery is not needed for the time being. At the late stage of cervical spondylosis, serious numbness, weakness, inflexibility of the limbs, unstable walking and dysfunction of the two bowels begin to appear, at this time the spinal cord compression is serious, sometimes MRI can see the high signal of spinal cord degeneration, if not early surgery to lift the compression, the nerve compression can lead to severe nerve necrosis, even if the surgery surgery will not be good, so early surgery is required.
