Periprosthetic fractures (PPFs) present unique challenges to orthopaedic surgeons in terms of limited cortical fixation options, poor bone quality, cement mantles, and stress risers introduced from the prosthesis. Various fixation strategies have been used in PPFs including the use of intramedullary nails, locked plates, unicortical locking screws, cerclage wires and cables, double-plating techniques, and allograft struts. Here, we will review the biomechanics of various fixation strategies used in PPFs.
假体周围骨折（PPF）在皮质固定选择有限、骨质量差、骨水泥覆盖层以及假体引入的应力集中等方面给骨科医生带来了独特的挑战。在 PPF 中已经使用了各种固定策略，包括髓内钉、锁定板、单皮质锁定螺钉、环扎钢丝和电缆、双钢板技术和同种异体支柱。在这里，我们将回顾 PPF 中使用的各种固定策略的生物力学。
