@annie1 I don't have experience with spine surgery and osteoporosis except that my elderly mom had a compression fracture due to osteoporosis. Sometimes surgeons ask patients to do bone building with an endocrinologist before performing spine surgery. That question should be answered by your specialist. I would also be careful about how you ask because surgeons don' want to feel like their opinion is being challenged by something a patient reads online. My therapist would say let them be the brain in the room. You can ask if your condition of osteoporosis creates more risk with the procedure they suggest.
