Abstract:
Objective:To compare the short-term outcomes of femoral neck system (FNS) and dynamic hip screw (DHS) in the treatment of femoral neck fractures.Methods:A retrospective analysis was performed of the 105 patients with fresh femoral neck fracture who had been treated by FNS fixation from September 2019 to October 2020 or by DHS fixation from January 2018 to October 2020 at Department of Orthopaedics, The Third Hospital Affiliated to Peking University. In the FNS group of 54 cases, there were 18 males and 36 females with a mean age of (60.7±15.2) years; in the DHS group of 51 cases, there were 14 males and 37 females with a mean age of (63.3±13.2) years. The 2 groups were compared in terms of hospital stay, operation time, intraoperative blood loss, incision length, intraoperative fluoroscopy frequency, qualify of reduction, and femoral neck shortening length, Harris hip score and complications at the last follow-up.Results:The 2 groups were comparable due to insignificant differences in their preoperative general data or follow-up time ( P>0.05). In the FNS group, the median operation time [45.0 (40.0, 59.0) min], intraoperative blood loss [30.0 (20.0, 50.0) mL], incision length [4.0 (4.0, 5.0) cm], intraoperative fluoroscopy frequency [10.5 (9.0, 12.0) times] and hospital stay [2.0 (2.0, 4.0) d] were significantly superior to those in the DHS group [72.0 (55.0, 89.0) min, 50.0 (30.0, 50.0) mL, 7.0 (6.0, 8.0) cm, 18.0 (15.0, 19.0) times, and 3.0 (3.0, 6.0) d] (all P<0.05). There were no statistical differences between the 2 groups in quality of reduction, length of femoral neck shortening, failure rate of internal fixation or Harris hip score at the last follow-up ( P>0.05). There were no such surgical complications as deep infection or femoral head necrosis in either of the 2 groups. Conclusions:In the fixation of femoral neck fractures, both FNS and DHS may lead to fine short-term outcomes. However, compared with DHS, FNS exhibits advantages of simplicity, minimal invasion, less surgical trauma and intraoperative fluoroscopy frequency, and reduced operation time and hospital stay.
