Abstract: Objective To compare the effects of proximal femoral nail anti-rotation (PFNA) and dynamic hip screw (DHS) internal fixation in treating senile intertrochanteric fractures.Methods From January 2014 to March 2016,100 elderly patients with intertrochanteric fracture in the Second People's Hospital of Yaodu District were selected and randomly divided into two groups according to the digital table,with 50 patients in each group.The PFNA group and DHS group were treated with PFNA and DHS internal fixation,respectively.The curative effect,fracture healing,complications and hip function scores were compared between the two groups.Results The treatment excellent rate of the PFNA group (92％) was significantly higher than 76％ of the DHS group (x2 =4.762,P ＜ 0.05).The fracture healing time of the PFNA group was (15.37 ± 6.29) weeks,which was significantly shorter than (23.64 ± 8.17)weeks of the DHS group (t =5.671,P ＜ 0.05).The incidence rate of complications of the PFNA group (6％) was significantly lower than 22％ of the DHS group (x2 =5.316,P ＜ 0.05);.After surgery,the Harri hip scores of the PFNA group and DHS group were significantly higher than those before surgery (t =11.330,5.788,all P ＜ 0.05),and the Harri hip score of the PFNA group after surgery was higher than that of the DHS group (t =5.147,P ＜ 0.05).Conclusion Compared with DHS,the clinical effect of PFNA internal fixation in the treatment of elderly patients with femoral intertrochanteric fractures is more significant.
