Abstract

Metastatic bony disease is a significant health issue, with approximately 700,000 new cases annually that tend to metastasize to bones. The proximal femur in the appendicular skeleton is commonly affected. Our study aimed to investigate mortality rates and hospital stay duration in patients with pathologic proximal femur fractures treated with either intramedullary nailing or arthroplasty within the Veterans Health Administration system. In total, 679 patients (265 arthroplasty, 414 intramedullary nails) were identified through ICD-9 and CPT codes from 30 September 2010 to 1 October 2015. Hospital stays were similar for both groups (arthroplasty: 10.5 days, intramedullary nails: 11 days, p = 0.1). Mortality was associated with increased age and Gagne comorbidity scores (p < 0.001). Arthroplasty showed a survival benefit in the log-rank test (p = 0.018), and this difference persisted in the multivariate analysis after adjusting for age and comorbidities, with a hazard ratio of 1.3. Our study reported evidence that arthroplasty is associated with increased patient survival even when accounting for age and comorbidities in treating metastatic disease of the proximal femur.
