Abstract
BACKGROUND: Surgical decision-making can be challenging when treating patients with osseous metastases. Numerous factors, including expected duration of survival, must be considered to ensure optimal operative stabilization of the affected bone. However, life expectancy of patients with metastatic carcinoma is often difficult to estimate. The goal of our study was to assess the associations of various clinical and demographic factors with survival time after intramedullary nail fixation of impending or completed pathologic femur fractures. METHODS: One hundred thirty-eight consecutive patients treated with intramedullary nail fixation for impending or completed pathologic femur fractures between 2005 and 2017 were included in this study. Factors related to patient survival were assessed with Cox multivariate survival analysis. For all analyses, p < 0.05 was considered significant. RESULTS: The median overall postoperative survival time was 8.4 months. Lower hemoglobin concentration (p = 0.001), lower albumin concentration (p = 0.002), and having a group 2 primary cancer (p = 0.001) were associated with shorter survival on multivariate analysis. When considering the subgroup of 88 prophylactically stabilized patients, lower hemoglobin concentration (p = 0.005), lower albumin concentration (p = 0.015), and having a group 2 primary cancer (p = 0.037) were predictive of shorter survival. CONCLUSION: Several factors are associated with shorter survival after intramedullary nail fixation of pathologic femur fractures. These factors should be considered by orthopedic surgeons when educating patients and determining appropriate treatment.
