Due to the instability of intertrochanteric fractures in elderly patients, various methods of reduction and fixation were introduced to obtain stable reduction and solid union, But there have been many controversies regarding advantages between anatomical reduction group and non-anatomical reduction group. The authors analyzed the 68 unstable intertrochanteric fractures out of total 94 cases of intertrochanteric fractures treated from Jan. 1988 to Jan. 1994 with mean follow-up 17 months and evaluated the radiologic and clinical results between those two groups. The results were obtained as follows: 1. The most common cause was low energy injury and according to the Tronzo classification, the type III was most common in 54 cases (79.4%). 2. The average union time was 14.0wks (84%), the union rate was low in the medialized reduction group(A-P) and anterior displaced reduction group(A-P), anterior displaced and anatomical reduction groups(Lateral). 3. The compression length more than 10mm of lag screw was deep in medialized reduction group(A-P), another displaced and anatomical reduction groups(Lateral). 4. The average length of lag screw sliding was 9.2mm and depth sliding of 6.8mm (74%) was occurred within immediate postoperative 1 month.
