Lumbar Fusion

I am having the following surgery done in 2 weeks. Posterior spinal fusion L3-Sacrum with instrumentation, laminectomy L3-L4 with possible posterior lumbar interbody fusion L3-L4.
You can say I am a bit paranoid about this surgery. My question is does this medical jargon mean I will be fused from L3 to S1?

That's what I thought. I had L4&5 fused in dec 2012. They tell me they are going to fuse L3 to S1. Which is what I need, but when I read the consent form I see exactly what you said. That's the only reason I posted here. I wanted to see if other read it the same way I did. In my original post I wrote the exact verbiage that's in my consent. Thanks for the reply!
