Abstract:
Objective To compare the clinical effect of proximal femoral nail anti-rotation(PFNA) and dynamic hip screw(DHS) internal fixation in the treatment of femoral intertrochanteric fracture.Methods 80 patients with femoral intertrochanteric fracture were selected as research subjects.They were divided into PFNA group and DHS group by random number table,40 cases in each group.The operation time,intraoperative blood loss,postoperative wound drainage,postoperative weight-bearing time,healing time,complication rate,Harris hip function score between two groups were compared.Results The operation time of the PFNA group was lower than that of DHS group(t=22.66,P＜0.05),the amount of bleeding in operation was less than that in the DHS group(t=54.85,P＜0.05),the postoperative wound drainage volume was less than that of the DHS group(t=16.85,P＜0.05),the weight-bearing time after operation was shorter than that in the DHS group(t=20.18,P＜0.05),and the healing time was shorter than that in the DHS group(t=22.00,P＜0.05).The excellence rate of Harris hip function score in the PFNA group was 95.00％,which was significantly higher than 80.00％ in the DHS group,the difference was statistically significant(χ2=4.11,P＜0.05).The incidence rate of complication of the PFNA group was 7.50％,which was significantly lower than 25.00％ of the DHS group(χ2=4.50,P＜0.05).Conclusion Compared with DHS,PFNA internal fixation has the advantages of less operation time,less intraoperative blood loss,shorter healing time and low complication rate in the treatment of femoral intertrochanteric fracture.It is worthy to be promoted clinically.
