Because fragility fractures and periprosthetic fractures represent an increasingly common source of morbidity for the elderly population, all orthopaedic surgeons should be prepared to care for such injuries in their practice. Fractures in elderly patients appear to heal more slowly because of decreased numbers and responsiveness of osteoprogenitor stem cells, and stable fixation is more difficult to achieve. It is important to review the mechanical and biologic considerations relevant to the treatment of these challenging injuries.
由于脆性骨折和假体周围骨折在老年人群中引发疾病的情况日益常见，所有骨科医生在其临床工作中都应做好处理此类损伤的准备。老年患者的骨折似乎愈合较慢，原因是骨祖干细胞数量减少且反应性降低，而且更难实现稳定固定。回顾与治疗这些具有挑战性损伤相关的力学和生物学考量因素很重要。
