Objective To investigate the clinical effect of long proximal Asia femoral nail antrotation（ Ⅱ）（ PFNA-Ⅱ） in proximal-middle long-segment complicated femoral fractures. Methods 26 cases were treated with PFNA-Ⅱ,the clinical effects were evaluated according to Harris criteria and radiological examinations. Results All patients were followed up for 6 ~ 18 months. The operating time of all cases was 40 ~ 90（58 ± 13. 6） minutes,and the mean blood loss during surgery was 50 ~ 160（77. 8 ± 25. 6） ml. No serious complications and aggravation occurred during perioprative period. According to Harris criteria,the clinical results were excellent in 17 cases,good in 6 and fair in3. No caxa vara,infection,cut out or breakage of the implants,secondary fractures or DVT occurred. Conclusions Long PFNA-Ⅱ is better suited for the proximal femur of Asian patients. Long PFNA-Ⅱ is an effective and minimally invasive method for proximal-middle long-segment complicated femoral fractures,which is better method with high fixation strength,early functional recovery,a high rate of bone union,compatible biomechanics characteristics and less complications.
