Subtrochanter Fractures of the Femur-Results of Treatment with Dynamic Hip Screw Devices
並列摘要
From July 1984 to Dec 1993, 145 patients with 146 subtrochanteric fractures were treated with dynamic hip screw devices. This injury was the result of high-energy trauma in 80.0% of cases. Most cases were treated with dynamic hip screw devices alone, and also with adjuvant bone graft in six cases. There were 1 case of wound infection, 1 case of fat embolism and 2 cases of pneumonia. Two patients died during hospitalization,and three died before fracture union.There were 140 cases followed up for periods ranging from periods ranging from 8-96 months. The average time for union was 5.7 months (range: 3.5-10 months). Nonunion was found in 10 cases, and implant failure in 8. These complications are common in type Ⅳ and ШA fractures. The union rate was 87.2%. These results suggest that the dynamic hip screw device is one of appropriate methods of treatment in cases of subtrochanteric fracture, and that special attention should be given to types Ⅳ and ШA fractures.
