Early Outcome of Intracapsular Fracture Neck of Femur Managed with Femoral Neck System Versus Cannulated Cancellous Screws: A Prospective Comparative Study.

Introduction: CCS fixation is considered a gold standard for stabilization of displaced intracapsular fracture neck of the femur (DICNF). Recently, a minimally invasive implant has been developed for these fractures called the Femoral Neck System (FNS). Currently, there is no comparative prospective study to assess the superiority of one over the other. Thus, this study was conducted to compare the functional and radiological outcomes of DICNF managed with FNS and CCS in adults. Materials and Methods: A prospective comparative study was performed in patients between 18 and 60 years of age with DICNF managed with FNS or CCS. Thirty-four patients ( Results: The mean Harris hip score in the CCS subgroup was 72.82 ± 29.34 compared to 88.82 ± 23.58 in the FNS subgroup, which was statistically significant. Intraoperative duration in the CCS group was 53.41 ± 18.94 min and in the FNS group was 38.12 ± 6.81 min, Conclusion: At 12 months of follow-up, the mean HHS was 88.82 in the FNS subgroup and 72.82 in the CCS subgroup where the difference was statistically significant. The mean operating time in the FNS subgroup was 38.12 min, and in the CCS subgroup, it was 53.41 min where the difference was statistically significant. 94.1% of cases in FNS and 88.2% of cases in the CCS group attained union at 12 month follow-up. However, the difference between 2 subgroups was not statistically significant.
