Abstract

Background: Long-term Bisphosphonate consumption has been reported to be associated with the incidence of atypical or insufficiency fracture, particularly in the proximal femur. We observed a case of acetabular and sacral insufficiency fractures in a patient with a long-term history of Alendronate consumption. Case presentation: A 62-year-old woman was admitted with a complaint of pain in right lower limb following low-energy trauma. The patient had a history of Alendronate consumption for more than 10 years. The bone scan revealed increased radiotracer uptake in the right side of the pelvic, proximal right femur, and sacroiliac joint. The radiographs showed type 1 sacrum fracture, acetabulum fracture with femur head protrusion into the pelvis, quadrilateral surface fracture, fracture of the right anterior column, and right superior and inferior pubic fracture. The patient was treated with total hip arthroplasty. Conclusion: This case highlights the concerns regarding long-term bisphosphonate therapy and its potential complications. © 2023, The Author(s).
