The information regarding type of fusion is confusing. A laminectomy (called a Gill procedure in this situation) is appropriate. The fusion part is confusing. Why does he want to fuse both L4-5 and L5-S1? Is L4-5 very degenerative or is he not planning to add a TLIF (see website) to the fusion and needs to add L4-5 to create a longer level arm.
My opinion with this limited information would be to just fuse L5-S1 with a TLIF unless L4-5 is so degenerative that it could not stand alone to support the spine when L5-S1 is fused.
