Abstract

There have been case reports of proximal femur insufficiency fractures in patients who have previously undergone bariatric surgery. We present a follow-up case of a patient who developed bilateral complete proximal femur insufficiency fractures several years after bariatric surgery. Our patient underwent bilateral intramedullary fixation with a satisfactory postoperative outcome. We review and discuss the definition and pathogenesis of atypical femur fractures (AFFs), which may represent a larger category of insufficiency fractures not exclusive to bisphosphonate use, which includes patients with fractures after bariatric surgery.
