What do OA, DDD, and spondylosis have in common?

• A. They are age-related or secondary to trauma or biomechanics of the spine.
• B. They are all inflammatory conditions.
• C. They involve no changes in the disc.
• D. They do not cause any bony changes.

Answer: (A)

Degenerative spine changes driven by aging and mechanical stress are the common thread here. Osteoarthritis of the spine refers to degeneration of the facet joints and related joint surfaces; degenerative disc disease means the intervertebral disc loses hydration and height, with annulus changes and potential nerve root compression; spondylosis is the broader term for these age- and wear-related changes in the spine, including osteophyte formation and facet joint degeneration. Together, they reflect wear-and-tear and sometimes prior trauma affecting spinal structures, rather than being primary inflammatory diseases. They are not inflammatory conditions in the classic sense, since these processes are primarily degenerative rather than driven by systemic inflammation. They do involve changes to the discs in at least one of the conditions (degenerative disc disease) and they clearly involve bony alterations like osteophytes and facet joint changes, which contradicts the idea that no bony changes occur.
