Periprosthetic femoral fractures (PPFs) are challenging complications following total hip arthroplasty, especially in cases with compromised bone stock. We present 2 cases of Vancouver Type B3 PPF treated with a monoblock cementless long-stem prosthesis, using cement only for distal fixation. This technique provided initial stability, allowing early mobilization and eventual fracture healing with bony ingrowth. Radiographic follow-up demonstrated successful outcomes with no significant complications. Our results support the potential of this method for treating complex PPF cases, offering a solution for patients with inadequate bone quality where standard cementless fixation may be insufficient.
人工关节周围股骨骨折（PPF）是全髋关节置换术后具有挑战性的并发症，尤其是在骨量受损的情况下。我们报告2例温哥华B3型PPF病例，采用一体式非骨水泥长柄假体治疗，仅使用骨水泥进行远端固定。该技术提供了初始稳定性，允许早期活动并最终通过骨长入实现骨折愈合。影像学随访显示结果成功，无明显并发症。我们的结果支持这种方法治疗复杂PPF病例的潜力，为骨质量不足的患者提供了一种解决方案，而标准的非骨水泥固定可能不足。
