Abstract

INTRODUCTION

Peri-implant fractures (PIF) reported after cannulated screw and dynamic hip screw fixation historically occur distal to the implant within the subtrochanteric region secondary to the development of a stress riser. Newer implant designs for femoral neck fractures have attempted to combine the benefits of minimally invasive techniques without forgoing rigid angular stability but bring new potential complications.

CASE REPORT

We present a case of an intertrochanteric PIF in the setting of a non-displaced femoral neck fracture treated with the DePuy Synthes Femoral Neck System (FNS).

CONCLUSION

We present this case of a unique PIF pattern with the hope of identifying a potential complication associated with the novel FNS. Furthermore, we present a successful treatment option avoiding the need for conversion to hemiarthroplasty.

摘要

引言

历史上，空心螺钉和动力髋螺钉固定后报道的植入物周围骨折（PIF）发生在植入物远端的转子下区域，继发于应力集中器的形成。用于股骨颈骨折的新型植入物设计试图在不放弃刚性角稳定性的情况下结合微创技术的优点，但带来了新的潜在并发症。

病例报告

我们报告一例采用DePuy Synthes股骨颈系统（FNS）治疗的无移位股骨颈骨折患者发生的转子间PIF。

结论

我们报告这例独特的PIF模式病例，希望识别与新型FNS相关的潜在并发症。此外，我们提出了一种成功的治疗方案，避免了转换为半关节置换术的需要。
