Background: The optimal method for internal fixation of femoral neck fractures in younger individuals remains a subject of debate. This meta-analysis systematically evaluates and compares the clinical outcomes of the femoral neck system (FNS) versus cannulated compression screws (CCS) in this demographic. Methods: A comprehensive search of the Cochrane Library, PubMed, Web of Science, and Embase databases was conducted from their inception until March 2024 to identify cohort studies comparing FNS (n=265) and CCS (n=326) in individuals aged 14-65 years with femoral neck fractures. The quality of the studies was assessed using the Newcastle-Ottawa Scale, and data were analyzed using RevMan 5.4, employing standard mean differences (SMD), weighted mean differences (WMD), and 95% confidence intervals (CI). Results: Nine high-quality studies encompassing 591 patients were included in the analysis. Compared to CCS, FNS significantly reduced healing time (SMD=16.30, 95% CI 3.79-28.82, P<0.001), decreased intraoperative fluoroscopy usage (WMD=-8.14, 95% CI -9.82 to -6.46, P<0.001), improved the final Harris score (WMD=-3.43, 95% CI -4.08 to -2.77, P<0.001), and lowered complication rates (relative risk [RR]=1.05, 95% CI 0.92-1.19, P=0.50). However, FNS was associated with a longer incision (WMD=0.84, P<0.001) and increased blood loss (WMD=16.30, P=0.01). No significant differences were observed in operation time (P=0.19), length of hospital stay (P=0.52), or excellent-to-good rate (P=0.50).Conclusions: The Femoral Neck System (FNS) may present potential benefits in specific outcomes, notably in terms of expedited healing and enhanced functional rehabilitation. The results of this study advocate for the consideration of FNS as a preferred treatment option for active populations, where the reduction of radiation exposure and the optimization of long-term outcomes are prioritized, notwithstanding its marginally greater invasiveness.
