Abstract: Objective To compare the effect of PFNA and DHS on the treatment of senile patients with femoral intertrochanteric fracture.Methods 89 senile patients with femoral in-tertrochanteric fracture were divided into two groups.42 patients were treated with PFNA and 47 patients were treated with DHS.Incision length,amount of bleeding,operation time,postoperative functional recovery and intraoperative complications were compared between two groups.Results The incision length,intraoperative bleeding volume,the time of fracture healing and surgical time as well as postoperative functional recovery in the PFNA group were significantly better than those in the DHS group.Conclusion Application of PFNA in the treatment of senile patients with femoral intertrochanteric fracture is simple,and it has advantages such as fewer traumas and bleed-ing,shorter operation time and desired effect,which is especially helpful for senile patients with in-tertrochanteric fracture.
