Cervical spondylotic myelopathy (CSM) is a narrowing of the spinal canal through which the spinal cord passes. Pressure is put on the spinal cord causing many symptoms in the neck, arms, and hands.
Many surgeons say that surgery for this condition doesn't improve patient's symptoms. Since it's a degenerative condition, over time, the problem may get worse and the symptoms can come back.
There are only two studies reported comparing patients who had surgery with patients who didn't have surgery. The results of both studies were the same: there was no major difference in results for these two groups.
Doctors agree that more study is needed. It would be good to have a large group of patients and compare the results of various treatment options.
