Objective  To analyze effect of percutaneous anti-rotation of the proximal femoral nail(PFNA) internal fixation on hip joint function and quality of life in elderly patients with intertrochanteric fracture.

  Methods  A total of 92 patients with femoral intertrochanteric fracture admitted to our hospital were enrolled in the study, and were divided into two groups by different surgeries. The patients in the control group(n=46) were treated with internal fixation of dynamic hip screw (DHS), and those in the experimental group(n=46) were treated with percutaneous PFNA. The excellent rate of hip function and surgical index were compared between the two groups. Quality scores of two groups before and after 3-month treatment during 3-month follow-up was compared.

  Results  The excellent rate of hip function in the experimental group was significantly higher than that in the control group (95.65% vs. 69.57%, P<0.05). The operation, the time of bed-off, the length of hospital stay and the length of the incision were significantly shorter in the experimental group than in the control group(P<0.05). The quality of life score of the experimental group after 3 months of treatment were significantly higher than that in the control group(P<0.05).

  Conclusion  Percutaneous PFNA internal fixation has higher excellent rate, can promote the early postoperative bed-off activity, and improve quality of life and prognosis for elderly patients with femoral intertrochanteric fractures.
