BACKGROUND: Pathologic fractures of long bones are common complications of the metastatic disease; however, the influence of the primary tumor, the stage of metastatic disease, different surgical techniques, and the postoperative mobility on the postoperative survival has not been clearly defined. The aim of this retrospective study was to evaluate outcome after surgical treatment for pathologic femur fractures. PATIENTS AND METHODS: A consecutive series of 142 patients with metastatic fractures of femur were retrospectively studied. The operative treatment was based on intramedullary fixation (n = 94), gliding screws (n = 15), other extramedullary fixation devices (n = 7), and arthroplasty (n = 23). RESULTS: Seventeen percent and 6% of the patients survived 1 year and 2 years, respectively, postoperatively. Postoperative survival was higher in patients with pathologic femur fractures because of breast carcinoma than in patients with other primary tumors. The rate of complications for patients with intramedullary stabilization, gliding screw fixation, and endoprosthetic replacement was 3.2%, 20%, and 8.6%, respectively. CONCLUSION: Although many studies describe the endoprosthetic replacement as the safer method to treat pathologic femur fractures, our data showed that intramedullary stabilization and endoprosthetic replacement to be safe, and equivalent alternatives to treat complete pathologic fractures of the femur in patients with advanced metastatic disease.
