I drew a little diagram above that demonstrates how this works. The fact that the low back now has less of a curve after neck surgery means that the discs there will take on more body weight. This can lead to eventual low-back-disc failures, like bulges, degeneration, and herniations. On the other hand, if you have too much curve, it may be possible to correct that through the neck? Not sure that’s a smart idea, but you can read between the lines of the research to see that that’s where the spine-surgeon authors want to head.
