Sorry to hear of your latest troubles, and this is just a guess, so make sure you ask your surgeon this question....but I'm thinking this is a spacer wedge type of device, and will be put in to keep the disk from collapsing further. Since it does not involve a fusion, I would think the recovery time would be minimal.
I really don't know much about this type of device and it's purpose, so again, you will need to ask your Dr about it. Hopefully another member with this particular experience will leave a comment here for you.
Glad you stopped by!
