@emma_rooks @AmonMaritza 1. No, we have no assurance those are his films
2. You are absolutely correct, this is not a true lateral view. The endplates are off. We also have no AP or pre-op images to compare
3. He has a grade I L5-S1 spondylolisthesis on this view, possible pars defects at this level. No idea what he looked like before surgery

That being said:

>absent acute spinal trauma, why was a 20-something year old fused in the first place?!
>top L5 screw is riding the endplate, suboptimal
>S1 screws are far too long, rookie mistake, you try to subtract 5mm at that level
>they did not appear to place an interbody graft, not ideal in a young patient
>WHY WAS HE FUSED IN THE FIRST PLACE (most important question)
