RESUMO
Objective To discuss surgical method and clinical curative effect of the headless compression cannulated screw percutaneous minimally invasive treatment of Evans -JensenⅠ,type Ⅱ of intertrochanteric fracture. Methods The clinical data of 21 cases of Jensen Evans and type II femoral intertrochanteric fractures who were treated by headless compression cannulated screw minimally invasive treatment were retrospectively annalyzed.In all patients,male in 6 cases,female in 13 cases;63 -86 years old,average 71.79 years.According to the Evans -Jensen norm and curative effect evaluation according to the improved Harris standard.Results Follow -up time was 6 -18 months (mean 12.15 months),two of them respectively in the six months after death from acute myocardial infarc-tion (ami)and 11 months of cor pulmonale,the rest of 17 cases of bony healing.Harris,the average score (67 -95points)at the time of the last follow -up,including 14 cases of optimal good in 2 cases,fair 1,poor in 1 case,was 88.89%.Conclusion Headless compression cannulated screw percutaneous minimally invasive treatment of Evans-Jensen Ⅰ,type Ⅱ intertrochanteric fractures has the advantangtages of minimally invasive,reliable fixation,high rate of fracture healing,allowing early hip not functional exercise load conditions and obtaining ideal therapeutic effect.
