Linda can answer better but I can tell you what I think is the case.
As far as I know, pedicle screw constructs tend to be hypokyphosing.
I think flat-back refers to the loss of sagittal curve in the lumbar. Thus it is irrelevant to your fusion.
PJK and DJK ONLY potentially occur in fused patients.
There are no dumb questions.

If they do not prevent kyphosis in the fused area removing rods may be a good choice for those left with flat-back after surgery.
2. Do rods prevent proximal junctional kyphosis (PJK) or distal junctional kyphosis (DJK)?
Sorry for the dumb question.
