PY - 2020 DA - 2020/12/03 TI - Risk of complete atypical femur fracture with Oral bisphosphonate exposure beyond three years JO - BMC Musculoskeletal Disorders SP - 801 VL - 21 IS - 1 AB - Bisphosphonate (BP) therapy has been associated with atypical femur fracture (AFF). However, the threshold of treatment duration leading to increased AFF risk is unclear. In a retrospective cohort of older women initiating BP, we compared the AFF risk associated with treatment for at least three years to the risk associated with treatment less than three years.
