We consecutively treated 45 femoral trochanteric fractures in 45 patients (18 men, 27 women) with the adjusting sliding (AS) hip screw between February 2002 and July 2003. The mean age for them was 79.7 years (range, 46-96 years), and the follow-up period was 4 months (range, 2-12 months). According to Evans classification, 20 cases were the stable type, and 25 were the unstable type. To assess the utility of the AS hip screw on both types, we reviewed ability gait, surgical complications, and radiological findings. The pretrauma ability gait was maintained in 80% of the stable type 16 of 20 cases and in 76% of the unstable type 19 of 25 cases, respectively. There were no surgical complications such as cutting out, breakage implant, or infection in any case. The radiological examination revealed that all of the fractures had good bony fusion. These results indicate that the AS hip screw yielded desirable outcomes in both types. The good results were attributed to the firm reduction achieved at operation, and the design of the plate which allowed manipulation even after insertion of the lag screw into the femoral head.
