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.
