Objectives In order to compare the short-term clinical effects differences between the femoral neck system (FNS) internal fixation and total hip arthroplasty(THA) on unstable femoral neck fractures.Methods A retrospective analysis was conducted on 37 cases of unstable femoral neck fracture admitted to our hospital from July 1, 2020 to June 30, 2023. The cases were divided into an FNS group (21 cases) and a THA group (16 cases) based on surgical methods. And a comparative analysis was performed between the cohorts regarding demographic characteristics (sex, age), perioperative parameters (length of hospital stay, surgical duration, intraoperative blood loss), and postoperative functional outcomes (Visual Analog Pain Score and Harris Hip Score assessments).The operative time，length of hospital stay and intraoperative blood loss in FNS group were significantly lower than those in THA group, and the time of weight bearing on the ground was significantly longer than that in THA group (P < 0.01). The comparative analysis revealed comparable outcomes in postoperative pain intensity (VAS) and functional recovery (HHS) between the cohorts, with both parameters demonstrating statistically equivalent values (P > 0.05).For unstable femoral neck fractures, FNS and THA were equally effective. Although shortening and necrosis were observed in the FNS group, no statistically significant difference in postoperative complications was found between the two groups. The operative time of FNS was shorter, with less intraoperative bleeding. However, the earlier weight-bearing time of THA was more conducive to the recovery of limb function.
