Outcome and Safety of Femoral Neck System (FNS) In the Treatment of Femoral Neck Fracture: A Prospective Study

Background: Femoral neck fractures are common injuries associated with significant morbidity and functional impairment. Multiple treatment modalities exist, including cannulated cancellous screws (CCS), dynamic hip screw (DHS), hemiarthroplasty, total hip replacement, and the recently introduced Femoral Neck System (FNS). The objective is to evaluate the clinical outcomes and safety of the Femoral Neck System (FNS) in the management of femoral neck fractures. Material and Methods: This prospective study was conducted in the Department of Orthopedics at Government Medical College, Srinagar. A total of thirty patients presenting with femoral neck fractures were included in the study. All patients underwent thorough clinical and radiological evaluation at presentation and during follow-up. Key outcome parameters assessed included operative time, fracture union rate, and procedure-related complications. Functional outcomes were evaluated using the Harris Hip Score. Patients were followed for 6 months to assess radiological healing and functional recovery. Results: The mean age was 44 years (range: 18–60 years). The average operative time ranged from 35 to 60 minutes. Mean radiological union was achieved at 12–15 weeks. Union was observed in 28 patients (93.33%). Nonunion occurred in 2 patients (6.66%). One case of avascular necrosis required total hip replacement. Functional outcomes improved significantly, with the mean Harris Hip Score rising from 78.8 to 92.3. Conclusion: FNS is a minimally invasive, biomechanically stable fixation method with high union rates and low complication rates, making it a promising option for femoral neck fractures.
