A 54-year-old woman developed stage IV breast cancer 8 years prior. Chemotherapy was administered, and she was started on zoledronic acid treatment for her bone metastases.

Twenty months later, she developed another atypical femoral fracture in her left femur and underwent intramedullary nail fixation.
