[Treatment with bisphosphonates as a possible cause of bilateral spontaneous atypical femoral fracture].

In recent years, case reports have suggested an association between long-term bisphosphonate treatment and spontaneous atypical femoral fractures. We present a case with a 67 year-old female who was treated with bisphosphonate for eight years and within one year sustained bilateral spontaneous atypical femoral fractures preceded by uncharacteristic hip/thigh pain. X-ray of proximal femur is indicated in patients with long-term bisphosphonate use and non-traumatic hip/thigh pain.
