OBJECTIVE: To investigate the complications of surgical treatments for femoral intertrochateric @entity174 using @entity572 ( @entity572 ). METHODS: From Jan. 2002 to Dec. 2007, sixty-nine @entity1 with intertrochanteric @entity174 were treated by @entity572 fixation included 27 males and 42 females,with an average age of 72.9 years ranging from 53 to 96 years. According to Evans classification there were 10 cases in type I ,21 in type II, 22 in type III, and 16 in type IV, of which 51 @entity1 (73.9%) suffered from @entity66 preoperatively. RESULTS: Fifty-seven @entity1 were followed up for 8 to 70 months (41 months on average). Four @entity1 died, 17 cases occurrenced systematic complications postoperatively. Internal fixation related complications occurred in 12 @entity1 . There were 8 cases with mechanical failure of @entity572 including 4 of screw loosen,3 of cutting-out of device through femoral head and neck and 1 of plate breakage. Five @entity1 had a @entity3192 , and delayed union occurred in 4 @entity1 . CONCLUSION: Unstable @entity174 pattern produced high percentage of mechanical failure. In such cases @entity572 should not be the first choice for treatment. The appropriate treatment should be in relation to pre-operative @entity174 stability and @entity170 .
