@ariespumpkin, It looks like your timing is good.
"Case reports then appeared of new, often multiple, vertebral fractures that developed in patients within a few months of stopping denosumab — termed “rebound-associated” fractures. "

If your plan is to stop Prolia, you would want to consider a bisphosphonate. Reclast is usual after Prolia, but there can be fierce side effects, life changing for some. You may be one of the many for whom Reclast isn't much of a problem. Some people have sufficient protection from alendronate (Fosamax).
Best wishes for your surgery and after.
