Abstract: Objectives: Assess mortality and complications in patients with chronic kidney disease (CKD) after fixation of lower extremity fractures. Design: Retrospective cohort. Setting: Single academic level 1 trauma center. Patients: Four hundred seventy-six patients with CKD and operative lower extremity fractures (pelvis to ankle). Intervention: Patients were grouped according to preoperative glomerular filtration rate (GFR) per the National Kidney Foundation Guidelines. Patients with moderate-to-severe CKD and end stage renal disease (ESRD) were compared with those with predisease state CKD. Outcome Measurements: Mortality and complication rates at time points up to 2 years or until death. Results: Patients with predisease state CKD were significantly less likely to have a complication within 2 years than patients with ESRD but not patients with moderate-to-severe CKD. One-year and 2-year mortality rate were significantly higher in the moderate-to-severe CKD (36.1%) and ESRD (49.0%) groups than in the predisease state CKD group. Compared to the patients with predisease state CKD, patients with moderate-to-severe CKD and ESRD both had increased odds of 1-year mortality, 2-year mortality, and a complication at 2 years after operative fixation of a lower extremity fracture. Patients with ESRD also had increased odds of 30-day and 90-day mortality compared with patients with predisease state CKD. Conclusions: Compared to patients with predisease state CKD, patients with moderate-to-severe CKD and ESRD had increased odds of 1-year mortality and 2-year mortality, as well as a complication at 2 years. Patients with ESRD had increased odds of 30-day and 90-day mortality compared with patients with predisease state CKD. Two-year mortality rate was 49% in the ESRD group. Level of Evidence: Therapeutic level III.
