Abstract：Objective To explore the clinical effect of total hip arthroplasty (THA) or fixation renovation for failed internal fixation of proximal femoral nail anti-rotation(PFNA) in unstable intertrochanteric fracture.Methods From Apr.2013 to Jul.2015,twenty-five patients were treated with THA or fixation renovation after failed fixation of PFNA.There were 10 males and 15 females,with age ranging from 38-78 years (average,60.8 years).The average interval to second operation was 7.5 weeks (range,4-16 weeks).Twenty patients accepted THA and 5 patients took fixation renovation.All of them obtained more than one year follow-up.Results Only two patients had complications,who recovered well after treatment.Compared with preoperative condition,postoperative Harris hip score was improved significantly ((33.4±12.5)points vs.(85.6±9.2)points,t=16.81,P＜0.05),postoperative quality of life score was improved significantly ((65.2±10.2)points vs.(87.4±7.4) points,t=8.40,P＜0.05),and postoperative VAS score decreased significantly ((7.4±2.5)points vs.(4.0±2.2)points,t=5.11,P＜0.05).Conclusion THA or fixation renovation is effective salvage procedure after failed internal fixation of PFNA in unstable intertrochanteric fracture.
