What it means
Spondylosis is an umbrella word: it says the spine shows wear without naming one single change. It usually means some mix of thinner, drier discs, bone spurs (osteophytes) along the vertebrae, and arthritis of the small facet joints at the back. It is easily confused with spondylolysis, a crack in part of a vertebra, and spondylolisthesis, a slipped vertebra. Those are different findings.
When it matters
Spondylosis is found in most people as they age, and how much shows on a scan often does not match how much pain someone has. Doctors look more closely when the wear narrows the spinal canal or the openings where nerves leave. This deserves extra care in the neck, where the spinal cord itself can be pressed. What happens next depends on your symptoms more than on the scan.
Questions to ask your doctor
- Which levels are most affected, and how advanced is the wear?
- Is the spinal canal or any nerve opening narrowed?
- Could spondylosis explain my symptoms, or might something else?
