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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
