Evenity bone density treatment 5 years after a spinal fusion

I had a spinal fusion L2-L5 Dec 2018. I took Prolia for 2 years then stopped. My bone density was almost normal before surgery but is now osteoporosis. The doctor wants me to take Evenity for 1 year. It builds bone hopefully from osteoporosis to osteopenia. But I am really nervous about the hardware in my spine. I can't find a doctor who has prescribed Evenity to a patient with an existing fusion- only immediately after surgery to promote the bone adhering to the hardware. Has anyone take Evenity 4-5 years after a spinal fusion? Thank you.
