Structure question - S2? S3?

Are there actual discs at the S2 and S3 levels? I know there are nerve roots there, but from the looks of all the images of my back, I can't see any space for discs. I'm now fused from L3/4 to S1. I've been told to be careful with bending, lifting, twisting (BLT) because I would have a high possibility of rupturing the disc at L2/3. Should I worry about the lower levels too?


3 level spinal fusion, L3/4, L4/5, L5/S1, November 2008. Stiff, but I can walk.


  • ive never heard of s2 or s3, i know on my mri it only shows s1. some people have said they have an s2, but i dont know, never heard of myself
  • there are not exactly separate disks as we think of them in the rest of the spine, as they are more fused together to form that triangular bone that we refer to as the sacrum. what is more likely to happen is that you might develop additional stress on the si joints from that low a fusion.

    if you are interested, take a look at the following. i like the illustrations!!

  • I had heard other people mention having work done on S2 and S3 and I was thinking, WTH? Well, it's good to know that stuff is mostly all fused already anyway so, hopefully, I won't have to worry about it.
