Case: In recent years, atypical femoral fractures (AFFs) associated with bisphosphonate use have increasingly been reported, but current definitions limit their diagnosis to native femora. Atypical periprosthetic fractures are rare. We present a case of a Vancouver type-C periprosthetic fracture that was recognized as an AFF following nonunion. Conclusion: Bisphosphonate-associated AFFs can present as periprosthetic fractures. Delayed recognition of the role of bisphosphonates in a periprosthetic fracture may lead to a worse outcome, including a delay in diagnosis, delayed union, and failure of fixation.
