Objective To explore the clinical curative effect of locking titanium plate combined with mini-mally invasive percutaneous plate osteosynthesis ( MIPPO) technology in the treatment of intertrochanteric fracture . Methods 21 patients with intertrochanteric fracture were treated with locking titanium plate combined with MIPPO technology.Male in 8 cases,female in 13 cases,age was 61 -82 years old,average 72.1 years.They were typed according to the Evans standard and the curative effects were evaluated according to the improved Harris standard . Results The follow-up time was 12-35 months (average 22.5 months),after two months,one case died because of acute myocardial infarction ,the other patients were bony healing .The Harris scoring was 88.35 points at the time of the last follow-up(63 -95 points),including excellent in 14 cases,good in 4 cases,fair in 1 case and poor in 1 case,the excellent rate was 90％.Conclusion Locking titanium plate combined with MIPPO technology in the treatment of intertrochanteric fracture has advantage of minimal invasion ,reliable fixation,high rate of fracture heal-ing,it allows early hip joint exercise without weight to achieve an ideal treatment effect .
