Clinical effect of proximal femoral nail anlirotafion fixation in the treatment of intertrochanteric fractures

Objective To investigate the superiority of proximal femoral nail anlirotafion(PFNA) fixation in the treatment of intertrochanteric fractures. Methods 106 patients with intertrochanteric fracture were included in the study.According to different intemal fixation methods, they were divided into PFNA group and 2 dynamic hip screw(DHS) group, 53 cases in each group.The intraoperative conditions, the postoperative Harris score and the incidence of complications of the two groups were observed and compared. Results The length of incision in the PFNA group was significantly shorter than that in the DHS group[(4.50±1.35)cm vs.(12.63±2.50)cm], the operative time in the PFNA group was significantly shorter than that in theDHS group[(68.50±10.22)min vs.(102.36±17.55)min], the amount of blood loss in the PFNA group was significantly less than that in the DHS group[(152.40±35.08)mL vs.(298.33±70.11)mL], there were statistically significant differences between the two groups(t=20.832, 12.138, 13.551, all P 0.05). The excellent and good rate of Harris score in the PFNA group was slightly higher than that in theDHS group(94.34% vs.86.79%), the incidence rate of postoperative complications in the PFNA group was slightly less than that in the DHS group(5.66% vs.9.43%), but there were no statistically significant differences between the two groups(χ2=1.767, 0.541, all P>0.05). Conclusion PFNA internal fixation has characteristics of less surgical trauma, less bleeding, shorter operation time and less complications.It is easy to fracture healing and functional recovery of bone and joint.
