Periprosthetic fractures of the distal femur most commonly present as fragility fractures associated with relatively minor trauma. These injuries are often complicated by osteopenia of the distal femur secondary to stress shielding or osteolysis. Effective management of periprosthetic fractures of the distal femur requires knowledge of both fracture fixation techniques and revision arthroplasty. This article reviews the treatment options for these challenging fractures with a particular focus on the management of displaced fractures with a stable prosthesis.
股骨远端假体周围骨折最常见于与相对较小创伤相关的脆性骨折。这些损伤常因应力遮挡或溶骨导致远端股骨骨质疏松而变得复杂。有效管理股骨远端假体周围骨折需要了解骨折固定技术和翻修关节置换术。本文综述了这些具有挑战性骨折的治疗选择，特别关注稳定假体的移位骨折的处理。
