Objective To explore the efficacy of the treatment of unstable intertrochanteric fracture of aging people using hip arthroplasty by comparison with the use of DHS internal fixation.Methods Retrospective analysis was performed that 62 patients were involved including 24 cases of male and female 37 cases:aged 70 to 92,an average of (78.81 ±4.92) years,on the left side of the 43 cases,19 cases on the right side and 17 cases of DHS internal fixation,45 cases joint replacement during May 2010 to July 2012.Results All cases were followed up more than 1 year.Statistical analysis of observation indexes of two groups were made including the length of hospital stay,operation time,intraoperative blood loss,postoperative bed time and postoperative complications.The results show that the hip arthroplasty group was significantly superior tothe DHS internal fixation group (P ＜ 0.05).Conclusion Artificial hip replacement for treatment of unstable intertrochanteric fracture of senior person has obvious advantages.

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 .
