Abstract
Background: Fixation of femoral neck fractures is challenging due to diverse fracture patterns and biomechanical demands. The Femoral Neck System (FNS) improves fixation stability, but some fracture morphologies may require supplementary fixation.
Objective: To evaluate whether adding an extra cannulated screw to FNS, placed according to fracture morphology, enhances stability and clinical outcomes compared to FNS alone.
Methods: We prospectively studied 10 patients under 50 years with displaced femoral neck fractures treated using FNS plus an additional screw placed in a direction tailored to fracture type. Outcomes included radiographic union time, femoral neck shortening, Harris Hip Score (HHS), and complications over 12 months.
Results: Mean time to union was 13.6 ± 1.51 weeks. Femoral neck shortening averaged 3.1 ± 1.2 mm. Mean HHS at 12 months was 89 ± 5. One patient required revision for delayed union; no avascular necrosis cases occurred. Outcomes compare favorably with existing data on FNS alone.
Conclusion: Augmentation of FNS with an additional screw, placed based on fracture morphology, may improve fixation stability and functional outcomes in femoral neck fractures. Larger studies are warranted.
