The comparison of femoral neck system and cancellous screws internal fixation for femoral neck fracture

Background: The clinical efficacy of cancellous screws (CS) and femoral neck system (FNS) internal fixation in the treatment of femoral neck fracture (FNF) was compared in this research.Methods: Ninety-six patients with FNF were enrolled in this study. There were 47 cases in FNS group and 49 cases in CS group. The data of operation time, intraoperative bleeding, bed days and complication were recorded. Patients' joint function was evaluated by Harris score. At the last follow-up, the cost-effectiveness analysis of the two methods was analyzed according to the total cost of patients and hip function.Results: The intraoperative blood loss of the patients in FNS group was significantly higher than that in the CS group, but the length of hospitalization was significantly lower. There was no significant difference in the incidence of complications between FNS and CS. The joint function of FNS group was significantly better than that of CS group at 3 months after operation. There was no significant difference in Harris score between the two groups at the last follow-up. The overall medical cost of FNS group in 1 year is high. Cost-effectiveness analysis showed that compared with CS group, FNS group needs to pay 5761.1 yuan more for each additional Harris score.Conclusion: FNS and CS internal fixation can achieve satisfactory clinical results in the treatment of FNF. FNS treatment is helpful to the early functional recovery of patients, but the overall medical cost is high.
