An expert working group says osteoporosis can be diagnosed in postmenopausal women and older men with only marginally low bone density, if they have fractured certain bones in a minor mishap, show vertebral fractures on X-ray, or have high fracture risk for other reasons.
How serious is the risk of atypical femur fracture for osteoporosis patients on bisphosphonates, and when is a "drug holiday" justified? There are no definitive studies or guidelines, but here are some strategies to consider.
