Osteoporotic fractures are extremely common and will continue to increase. Methods of internal fixation must address challenges presented by architectural changes of weakened bone. The goals of surgery are to provide mechanically stable internal fixation with minimal biologic insult that provides rapid rehabilitation and early mobilization. Novel techniques and technology that reinforce preservation of periosteal blood supply and utilization of biomechanically stable constructs diminish failure rates. Advents in locking plate technology, intramedullary nail designs, bone augmentation, and multiple implant constructs maximize strength while mitigating axial, torsional, and bending failure modes to provide optimal patient outcomes.
骨质疏松性骨折极为常见，且发病率还将持续上升。内固定方法必须解决骨结构弱化带来的挑战。手术的目标是提供机械稳定的内固定，同时对骨骼的生物学侵袭最小化，从而实现快速康复和早期活动。强化保存骨膜血供和利用生物力学稳定结构的新技术和新方法可降低失败率。锁定钢板技术、髓内钉设计、骨增强和多种植入物结构的进步最大限度地提高了强度，同时减轻了轴向、扭转和弯曲失效模式，为患者提供了最佳的治疗效果。
