If I get a spinal fusion, I'm told that my neck won't be as flexible as it should be. Why is that and is there a way to avoid it?
A spinal fusion done in the neck is usually done because the discs are deteriorating, causing much pain and limited movement. If your surgeon has decided that a fusion is the best approach for you, this decision was likely made taking into account many factors about your particular situation.
You can always ask the surgeon why a particular procedure has been chosen over another, and this may help you understand the process a bit better.
Fusion does make the neck less flexible and this is one of the drawbacks, however, for many people, this procedure has reduced pain significantly and added to their quality of life.
