If the picture you uploaded is being used to demonstrate the 'thin' vertebrae, then we need to understand what we are looking at. That image is not a good a/p view of the area we are trying to see. It is very oblique.
If you think of plates for the prostheses like coins, when you are taking an a/p view, you want to see the image of the prostheses from an angle that shows a 'horizontal' view of the plates. If you take a picture of a quarter from a horizontal view (from the level of the table, with the quarter laying flat on the table; it will look like a line. If you take a top view, it will look like a circle. If you take an oblique view it will look like an oval.
When you are looking at an oblique view, there is no telling how those plates are sitting on the vertebral bodies.... you can't tell.
