There were 26 males and 20 females with the mean age of 39. 5 years old （ 19 - 55 years old）. All were new fracture cases, in which 16 were Garden Ⅱ , 18 were Garden Ⅲ, 12 were Garden Ⅳ. Results The follow up of the patients lasted for 1 - 5 years （ averagely 2. 4 years）. The average time of fracture union was 6.3 months fractures of all patients were reunion without screw＇s looseness and break. There were 19 cases with excellent effect and 22 cases with good effect. Excellent and good rate of hip joint＇s function was 89. 1%. and 1 patient experienced avascular necrosis of femoral head. The rate of good function of hip joint was 89. 1%.
