There are alternatives to bisphosphonates and they can actually grow new bone. An internist might not know about all of the alternatives. Many of us end up consulting endocrinologist who have subspecialty in osteoporosis. I would recommend that as the best drug choice(s) may require starting with a drug that actually can grow new bone and then, later, seguing onto a different drug to help maintain it. There's a lot to consider in terms of where to start for best likely results. And you might also be prescribed physical therapy or another protocol to help with the fracture while it heals or stabilizes?
