Hi and welcome!

You should include all of your medical information in the packet for the MEB. Nothing should be left out. Your ROM will be a huge determining factor in how they rate your spine. Once you get your ROM done you will better be able to compare it to the VASRD to see where you stand. I'm unfamiliar with Spondylosis, but if I find it in the VASRD I'll post it here and let you know.

But I'll stress again, make sure everything is included from your medical record into your packet. If your MTF (military hospital) has a medical records office, if you go in early enough one day you may be able to get a print out of your entire electronic medical records. I've done this a few times. In fact, it was required to have a complete up to date copy of my medical records before the packet could be submitted.
