Risk factors for complications within 30 days of operatively fixed periprosthetic femur fractures. J Clin Orthop Trauma. 2022;31:101925.

Methods: A retrospective cohort study of 231 patients with a periprosthetic femur fracture was conducted at an Academic, Level 1 Trauma Center. The main outcome measurement of interest was complications, as defined by the ACS-NSQIP, within 30 days of surgery. Results: 56 patients had 96 complications. Bivariate analyses revealed ASA score, preoperative ambulatory status, length of stay, discharge disposition, time from admission to surgery, length of surgery, perioperative change in hemoglobin, Charlson comorbidity index, cerebral vascular accident/transient ischemic attack, chronic obstructive pulmonary disease, diabetes mellitus, and receipt of a blood transfusion were associated with development of a complication (p < 0.1). Multivariate logistic regression showed length of stay (OR 1.11, 95% CI 1.03-1.19; p = 0.006), receipt of a blood transfusion (OR 2.48, 95% CI 1.14-5.42; p = 0.02), and diabetes mellitus (OR 2.17, 95% CI 1.03-4.56; p = 0.04) remained independently predictive of complication. Conclusions: Length of stay, receipt of a blood transfusion, and diabetes were associated with increased perioperative risk for developing a complication following operative treatment of periprosthetic femur fractures. Methods to decrease length of stay or transfusion rates may mitigate complication risk in these patients.en-USPublisher PolicyPeriprosthetic fractureFemurTransfusionComplicationArticle
