Abstract

Purpose: This study sought to compare the risk of subtrochanteric stress-riser fractures and biomechanical stability of the Femoral Neck System (FNS) versus multiple screw fixation (MSF). Methods: Eight paired cadaveric femurs were randomly assigned to FNS or MSF. Physiologic load mimicking single leg stance at the subtrochanteric region was applied to the constructs. Results: No constructs failed in the subtrochanteric region during loading. There was no significant difference in force (P = 0.364) or loading cycles (P = 0.348) between groups. Conclusion: FNS constructs were not associated with an increased incidence of iatrogenic subtrochanteric fractures or biomechanical stability versus MSF.
