Adjacent Segment Disease (ASD)


This is a problem you can develop after spinal fusion. It happens when the vertebrae above and below the fusion become weak and damaged. We say they "degenerate." And as they degenerate, more vertebrae are at risk for harm.


ASD is caused by stress on your spinal joints. When you have fusion surgery, two or more vertebrae are locked together. Afterward, as you bend and twist, you put extra stress on the nearby joints. They begin to degenerate, placing stress on even more vertebrae. These may begin to degenerate, too. This pattern can cascade through your spine.


When you have ASD, your spinal nerves can be irritated and compressed. You can have pain, numbness, tingling, and other problems.


To treat ASD, your doctor may recommend things like medications and physical therapy. You may need surgery, and possibly another fusion. Your doctor will create a care plan that's right for you.
