Abstract [Abstract]Objective To compare the clinical effect of dynamic hip screw (DHS),proximal femoral locking plate(LPFP),Proximal femoral anti-rotation intramedullary nail(PFNA)in the treatment of intertrochanteric fracture of the femur in the elderly.Methods All of 120 elderly patients with intertrochanteric fracture of femur admitted to our hospital from January 2017 to September 2018 were selected as the research objects.According to random ranking method,they were divided into the DHS group,LPFP group and PFNA group,40 cases in each group.The operation time,intraoperative bleeding volume,hospital stay and weight-bearing time,the incidence of complications,Harris hip function score before operation and at 2 weeks and 1 month after operation were compared among the three groups.Results The operation time,hospitalization time and weight-bearing time of the PFNA group were shorter than those of the DHS and LPFP group,and the intraoperative bleeding volume was less than that of the DHS and LPFP group,and the differences were statistically significant(P<0.001).There was no significant difference in the total incidence of complications among the three groups(P>0.05).The Harris hip function score of the three groups at 2 weeks and 1 month after operation was higher than those before operation,and the differences were statistically significant(P<0.05).The Harris hip function scores of the PFNA group at 2 weeks and 1 month after operation were significantly higher than those of the DHS and LPFP group,and the differences were statistically significant(P<0.001).Conclusion For patients with intertrochanteric fracture of femur,PFNA treatment can effectively reduce intraoperative bleeding volume and shorten the operation time,and the patients can move to the ground earlier,and the recovery effect of hip joint is good,the recovery time is short,and complications are not easy to occur after operation.It has better therapeutic effect.

Key words： Proximal femoral anti-rotation intramedullary nail Intertrochanteric fracture of femur in the elderly Randomized controlled analysis Dynamic hip screw Proximal femoral locking plate
