[Subtrochanteric pathological fracture on bisphosphonates].

Bisphosphonates have frequently shown their efficacy in the treatment of osteoporosis, including ibandronate and alendronate. But more and more mention is made in the literature of patients taking a long-term bisphosphonate and undergoing an atypical fracture associated with this therapy. These complications are most often femoral fractures in the proximal part of the femoral diaphysis. We report the case of a 73-year-old patient who had a subtrochanteric pathological fracture after a prolonged intake of alendronate followed by ibandronate.
