Atypical femoral fracture is a well-documented adverse reaction to bisphosphonate treatment, but may also have other causes. This dataset contains 433 radiographs from 149 patients with complete AFF, and 549 radiographs from 224 patients with normal femur fractures. There are no diagnoses of cancer, to reduce the risk of confounding by indication.

Atypical femoral fractures have a characteristic fracture pattern with the fracture running perpendicular to the longitudinal axis of the femur. The periosteal surface shows a focal cortical thickening (attempts to heal the fracture) and the fracture extends medially through unaffected cortical bone with a typical medial spike. These three radiographic signs are very typical findings for all kinds of stress fractures in cortical bone.
Each case including radiographs was evaluated by at least one senior consultant in orthopedics, and categorized into atypical femoral fractures (AFF) and normal fractures of the femoral shaft (NFF).
