Re: Thoracic Spine
Welcome to the board.
Mobic changes are a term used in radiology to describe and classify changes in the endplate of the vertebrae, changes in the bone itself. It is named for the radiologist that first wrote about the situation and classified it in 1988. (Endplates are the flat end of the vertebral bone that adjoins the disc. If you look at a photo of a normal spine, the edge of the vertebra will be smooth. When there are changes in the endplate, it looks jagged or rough).
Today most doctors think that this change in the endplate is a result of disc degeneration rather than a factor contributing to disc damage. It is present when there is some disc degeneration...but isn't always mentioned in the MRI report. There is usually edema and inflammation that go along these changes.
There are three classifications for the Mobic system -- Mobic I can progress into Mobic II...but current thinking is that Mobic I represents an active degenerative process and that it can be responsible for causing back pain.
So to put it simply, as I understand it, at the thoracic 5-6 and 6-7 there is some swelling in the bone tissue located in the endplates that is indicative of some degenerative changes going on in the segment of the spine.
