Abstract:
Objective:To investigate the efficacy of proximal femoral intramedullary nail antirotation fixation in the treatment of intertrochanteric fracture of the femur and its effects on Harris hip scores.Methods:Sixty-eight patients with intertrochanteric fracture of the femur who received treatment in Cixi People's Hospital from April 2018 to October 2019 were included in this study. They were randomly assigned to receive dynamic hip screw fixation (control group, n = 34) or proximal femoral intramedullary nail antirotation fixation (observation group, n = 34). Clinical efficacy, Harris score, surgical indicators, and the incidence of complications were compared between the two groups. Results:The response rate was significantly higher in the observation group than in the control group [94.12% (32/34) vs. 76.47% (26/34), χ2 = 5.81, P < 0.05]. The excellent and good rate of hip function as evaluated by Harris hip scores was significantly higher in the observation group than in the control group [91.18% (31/34) vs. 73.53% (25/34), χ2 = 6.05, P < 0.05]. The operative time, blood loss, incision length, and fracture healing time in the observation group were (51.66 ± 10.52) minutes, (120.26 ± 12.29) mL, (8.09 ± 2.62) cm, and (9.86 ± 2.67) weeks respectively, and those in the control group were (78.32 ± 12.23) minutes, (238.45 ± 17.85) mL, (12.95 ± 3.29) cm, and (13.65 ± 3.46) weeks, respectively. There were significant differences in these indices between the two groups ( t = 14.55, 14.03, 14.85, 14.60, all P < 0.05). The incidence of complications was significantly lower in the observation group than in the control group [5.88% (2/34) vs. 23.53% (8/34), χ2 = 6.51, P < 0.05]. Conclusion:Proximal femoral intramedullary nail antirotation fixation is superior to dynamic hip screw fixation in the treatment of intertrochanteric fracture of the femur. The former increases Harris hip score, decreases the incidence of complications, and is of great clinical innovation.
