Here’s something that surprises a lot of people: your discs don’t actually show up on a regular X-ray. Discs are soft tissue. What X-rays do show is the space between each pair of vertebrae, and that space is where your disc lives. Here’s how we measure disc height on X-ray, and what it tells us.
What a narrowed disc space tells us
A healthy disc holds the vertebrae above and below it apart at a fairly even height. When I see one disc space that’s noticeably thinner than the levels around it, that tells me the disc there has been under more stress and may be losing height and water content.
Disc narrowing has several possible causes, but it’s generally the result of extra pressure on that disc over time, often from the spine sitting in a less-than-ideal position.
What it looks like on our disc models
X-rays show the height of the space. If we need to see the disc itself, like whether it’s bulging or herniated, that’s what an MRI is for, and we’ll let you know if your exam points that way.
Can disc height change?
That’s the big question. I wrote a full post on what the research says about disc height after Non-Surgical Spinal Decompression. The short version: we measure, we set goals, and we re-measure, so you see what’s actually happening. Learn more about disc issues and Non-Surgical Spinal Decompression.
