Default Osteopenia in fused spine

I had a spinal fusion surgery (for scoliosis) with Harrington instrumentation (one rod) in 1972; the fusion is from T1 or T2 down to L1. Up to now I have not had any problems with my spine so I assume the fusion has remained intact. A recent bone densitometry shows that I have severe osteopenia in my lumbar spine (L1-L4), the BMD is 0.90 g/cm2 and the T score is -2.3. A general question: if any of the fused thoracic vertebrae were to fracture, would the fusion be compromised and the rod may become less stable. Or could it be the case that the fused vertebrae – as a rigid structure? - are ‘protected’ from osteoporotic fracture(s)?
