A simple way to look at it- you are basically putting a splint on the fracture by gluing it together. Then it can heal on its own.
Risks such as infection and the "glue" going to the wrong place and causing problems is rare.
One real risk- the glued vertebral body is "harder" than the adjacent bodies. There is, I have read, a small but real increased risk of fractures of the adjacent bodies. So, take care of yourself and treat whatever the cause of the original fracture- osteoporosis- etc.
I personally know several people that have had this done- with wonderful results.
Good luck
