@fify, @turkay1-- Disease is a special circumstance and I'm sure those treatments do help. But many times pathological fractures happen simply from old age, poor nutrition and lack of safety. I work in a nursing home and this is a problem that many of our residents deal with or have dealt with before arriving.
I think the best prevention method is making sure that we consume a healthy nutritious diet and get plenty of calcium and vitamin D which is necessary for our bones. For elders, we need to get safety rails for their home, especially for bathrooms and stairs. Even a minor fall can lead to a fracture in an elder person like the article said.
The residents at our nursing home are mostly over the age of seventy. This is when the risk of fractures are the highest. We have to pay close attention to all these factors for this reason.
