We’re going to look at xrays and how they represent the lumbar spine in general xrays are taken on a front to back or back to front view and on a side view the xray front to back view is this one and you can see how that is relatively comparable to the model where you have the vertebra lining up you see the vertebra lining up you have the sacrum down in this area here’s the sacrum the sacrum of course is connected to the pelvis through the sacroiliac joints.

On either side you can see the vertebra lineup straight and actually you can follow the ribs up on either side as they go into the thoraic spine up in this area on the side view you again can see the vertebra lining up one on top of another you cannot see the disc because there’s no bone in the disc but you can t get a good idea of what the disc looks like by the height and by the boney reaction to the disc you can see the facets in back here.
