Mortality and Financial Burden of Periprosthetic Fractures of the Femur

Abstract

This study examines patient factors to identify risks of 12-month mortality following periprosthetic femur fractures. Hospital charges were analyzed to quantify the financial burden for treatment modalities. Data were retrospectively analyzed from a prospective database at a university hospital setting. One-hundred and thirteen patients with a periprosthetic fracture of the proximal or distal femur were identified. Risk factors for 12-month mortality were analyzed, and financial data were compared between the various treatment modalities. In all, 14% of patients died (16 of 113) within 3 months and the 1-year mortality was 17.7% (20 of 113). Patients who died within 1 year had higher hospital charges (US$33 880 ± 25 051 vs US$22 886 ± 16 841; P = .01) and were older (87.6 ± 8.5 vs 81.5 ± 8.6; P = .004). Logistic regression analysis revealed age was the only significant predictor of 1-year mortality (P = .029, odds ratio 1.1). Analysis of financial data revealed 4 distinct groups (P
